Had the o2 Exec for 5-weeks or so, so outside the replace with new period.
Only noticed last night that there is a worrying bulge appearing in the case. It's on the surround of the keyboard, just above the left-hand softkey, to the right of the Xda Exec label, and dead in-line with the USB port. The bulge is about .75mm high, rises sharply at the left-end then falls gradually to a slight dip adjacent to the right-hand soft-key. It looks like something has expanded underneath the panel (over heating?) pushing the surface upwards. Has anyone else had this happen?
Might be pure coincidence, but my PDA is normally charged via USB, however this last week I've left it connected to the mains supply overnight - screen closed. The level difference is quite obvious to your finger when you press the soft-key, but because I don't use them, I've only just noticed it.
I always leave mine connected overnight, for the past 5 dats since I got mine. I did not notice any bulging.
Did you check te battery?
I had one of my phones suddenly develop a similar bulge, and it turned out that the battery overnight had expanded to twice the original width.
The battery (and the phone alas) was dead after that though.

Yes, I just checked it right now. As I had said I kept it plugged-in every night for 12 hours for 5 days since I got my EXEC. No bulges. It is only today that I am keeping it unplug and see how the battery last.

Have removed the battery and checked inside. Nothing appears distorted within the battery or compartment, no smell of overheating, etc.
Looking further it appears the bulge is just to the right of a screw holding the case halves together. Similarly, the dip near the right-hand softkey is at another screw location. So perhaps there was something (cable?) trapped when the case halves were originally assembled, and that I hadn't noticed the bulge until now.
Looks as though I'll have to answer the question: "Do you feel lucky, Punk?" and try opening the case up .
Er, anyone got any 'How to do it tips'? Hope they haven't hidden more screws under labels.
Do NOT open it up. You may well invalidate your warranty.
Contact your supplier and explain.
They will replace it or arrange for repair under warranty.
The 14 day return period does not invalidate your statutory rights of 28 days and then 1 subsequent year of trouble free operation.

My supplier is o2! They tell me that I will only ever get back a repaired/used unit. With this one exception the current unit is in as-new condition, no scratches or marks of any sort. A colleage has already gone through this. Despite complaints, he has received two "repaired" units, both badly scratched (including the screen) or dented, one caught fire the day it arrived, the other continually hangs even with no additional software installed.
Thank you all the same, but having the correct tools and anti-static environment, I would prefer my own repair!

Send it back to the manufactuer.

Doubt that's going to get me anywhere, since any contract I have is with the supplier not the manufacturer. Although the supplier could refer the matter to the manufacturer, the manufacturer has no legal responsibility to even talk to me, let alone repair or replace since they didn't sell me the product, o2 did!
I'm wondering if what you're seeing may be normal. Looking at my I-Mate Jasjar I'm seeing a similar thing. I can see it if I put the keyboard just below eye level and look across the top of the keyboard toward the back of the unit.
In my case, I have a slight dip just above my right softkey and also a bit of a bulge that goes all the way across from the middle of the left soft key to the dip above the right soft key. I'm not sure mine rises quite as sharply as you describe, nor does it seem to be quite as high, but it's definitely there. I had never noticed it before, but to me it looks like it's meant to be there.

Just had a (very close) look and mine shows similar bulges/dips in the case where you describe. No way I'd have noticed it without your description so maybe mine isn't as bad as yours. You really have to get the light right to see the unevenness in the case.
I don't see the problem though if your machine is working. :? Why risk invalidating the warranty by disturbing the case screws?

More of a problem when nobody else appeared to have the bulge, and after my colleague's Exec took up smoking.
Anyway, others might like to know that the case bottom is held on by more than the four visible screws in the battery compartment.

Hi all,
I need help,suggestions,anything with an issue I've had for a while. Since the time I started loading WM6 the screen has been randomly fading to white. I have LSVW latest rom 22/4 SE and 1.40.10 radio and 1.40oli although it doesn't matter what rom you load. I tried going back to WM5 and its better but now still fades to white as well.
on advise from oli and legolas I purchased a new battery but still have the same issue.
I have dropped my phone once which resulted in a crack to the right of the DEL/CR keys so could it be a HW issue and if you think so is it one I could open up the phone and fix?
Any and all help appreciated
IN FACT IF SOMEONE CAN RESOLVE THE ISSUE I WILL DONATE SOME CASH TO THEM!
test
Im updating to
LVSW 4-23 Full, Radio 1.40.30.00, SPL 2.10.Oli, IPL 1.04
seeing if any difference comes out.
This is not the first time this issue has been reported:
http://forum.xda-developers.com/archive/index.php/t-301003.html
The conclusion is that it's hardware related. It may be as simple as one of the internal ribbon connectors having a less than firm connection. It may be brought on my anything from physical movement or pressure to internal pressure if the device gats warm. However, it is possible that there is a failing component. IMHO, a case of take it for replacement/repair or first check connectors if your brave and not worried about a warranty.

HHmmm interesting thread .. the only issue i have out of that is the fade to white one.
Maybe Hardware .. i got the phone off ebay and now it has a crack in it .. so i dare say it isnt under warranty any more. (even though its a max of 6 months old).
It may also be software. I experienced the WSOD on my JASJAM when playing with the GPS-related DLL's. Once this problem appeared when switching on the camera. The screen would turn white and soft reset would not fix this, only power off/on would sort it out. Seems that the drivers do not reset (some of) the hardware to a known state on boot.
Had EXACTLY the same problem. Hoped it would be a software problem. Hard-reset a few times to no avail. Upgraded to a couple of the WM6 ROMs. No change. I did notice that when it was cool it tended not to happen, but after being on the phone a couple minutes or using the PDA for a while, it would do it AGAIN.
One weird thing I noticed was that if I did a Soft-reset and held down the Left Soft-key, I could "force" it to fade to white on start-up! VERY WEIRD.
I finally bit the bullet, and sent it back to Telstra to get it sorted. Didn't want to void warranty myself.
It has been just over 2 weeks since I sent it off, and They have sent this reply...

So, I guess it IS a hardware problem. But then again, that kind of reply, sounds a bit "dodgy" as it doesn't seem to "technical" does it?
Hope this helps.

Their reply was not very technical - does not surprise me however. The people who repair these devices are usually faced with some component/connection/screen or a m/board that needs replaced. They often fail to take account of something as basic as the case pressing on the screen or other components - particularly when device is warm. So they replace the component they think is faulty and then discover the problem is still there. With this issue in particular I think that there are no faulty components just the case is a fraction of a millimetre too tight for the internal components and hence swapping out parts can have no effect. With this fault I advise people to go for a replacement not a repair if possible.
NB: This issue should not be confused with white screen that may appear after installing particular software or when an application crashes, or when the flashing of a new ROM goes wrong! The hardware issue arises most commonly when the device gets warm or put another way goes white after maybe 10 minutes of use and will continue to go white even after hard reset.
Mike
I have this same problem! =(
My phone screen recently (4-5 days ago) started to go white. I never saw this happen with my own eyes but when i picked up my phone and its sleeping i push the power button to get to an all white screen. I can hear noises when i touch the screen but no image other than white. I can solve this by removing the battery and putting it back in, then my scren works fine....its not verry often just like 1-3 times a day.
I want to try a hard reset but have a question first: My phone is unlocked by the ebay guy i got it from, will a hard reset lock my phone back to Cingular?
Next i want to try upgrading my ROM and Radio and anything else...im looking in the wiki for instructions on how to do this. Any help? What else shouls i upgrade?
Ive only had my Hermes for around 2 months so im new to much of this.
THanks!
I recently purchased a Used Imate Jasjam (Ex Telstra Australia) with this issue.
I pulled the unit apart, and reseated and pressed the Power and LCD Display Data Cables... attempting to ensure they were firmly fastened.
I then upgraded to LVSW's Latest WM6 Release.
I have had the Phone go to White once in that timeframe since. I brought it back by pressing the power button of, then one again.
I don't feel that it's really a "100%" Faulty Part... Because it works fine othertimes. It almost seems as if connections or a Data Cable has an Issue.
I'm intending tonight and using the Phone over the weekend to see if the issue continues to occur.
BAD NEWS!!
Well, got my phone back after a bit over 3 weeks I think? I kept ringing the repair center and emailing. Finally they said it was ready, and was sent back to the shop I bought it from. Rang the shop "no it's not here yet, we will ring you"... now the repair centre to the shop is a 20 min drive... on the 3rd, I rang again at 1pm and "no it's not here yet, we will ring you when it arrives." At this point I was really getting p*ed off. So I went to the shop, and demanded, and guess what was AT the Shop?!?!?!
Anyway, after 1 friggin day, I have lost the Red & Green phone buttons! As of tonight the whole bottom section no longer work, and the screen has gone white again.
The repair report listed 3 things replaced...one was a "bezel" another was a "poly" something. I will get the report a list the replaced bits if anyone likes, but their descriptions are kind of strange if ya ask me.
Anyway, I have to send the phone back for repairs again, which could take another 3 weeks +, which I think is completely PATHETIC OF TELSTRA, especially for the fact they dont give the same phone or even similar to "loan" while I wait for my defective $1300 phone to get "repaired"... (more like 'fiddled with' & "yeah, she'll be right mate"...
GRRRRR!!!!
My girlfriends phone was having the same problem. Try popping out your SD card and putting the phone into/out of sleep and see if that brings back a visible screen. Thats how we determined her situation was a hardware problem and not a problem with the rom.

Yes, sadly this is kind of predictable as I said in an earlier post in this thread:
http://forum.xda-developers.com/showpost.php?p=1233420&postcount=7
This is why, as I said, get a replacement not a repair if possible. My view is that the individual components are fine but connectors come loose or the heat generated causes pressure to be put on the screen etc So it's a problem with some cases and how the innards in some cases get squeezed. So off course changing the top poly board, connectors, bezel gasket, may by pot luck make a difference but is just as likely to make no difference at all.

Status Report:
After having my phone playing Video's Through the Night (My Way of a "Stress Test" to Generate Heat) I woke up the find the screen to be "almost completely" White.
Usually its gone completely, however in this instance I was able to see the icons through the whitewash.
I put the phone into sleep and back out and the Display is fine again.
Being that these phones are much easier to pull apart and put back together than my old JasJar I might to do some further experimentation.
I think the issue will have something to do with either one of the following
- Heat
- Pressure on the LCD from Parts Around it
- Faulty Ribbon or Power Leads to the LCD
My suggestions
- In the Case of Heat... I'll run the Same Test, with the Phone Directly in front of a small airconditioning unit I have.
- In the Case of Pressure, I'm going to look and see if I can place some extra Insulation Tape or Similar on the Phone to relieve this
- I wish I could find somewhere to buy the Replacement Ribbon Cables but I don't know where I can get them in Australia... any ideas?

We wait to see. Mind you one guy on these boards found he could get half an hour from his device if he put it in the freezer for a while - so I'm not sure that air-con will be strong enough!!!
Mike
Well Results.....
After pulling apart the unit and reconnected, I think I found my cause to simply be excess pressure.
I've removed the "Black Plastic" Micro SD Card from its Blanking Plate.
Since I've done this... not one White Screen Whatsoever.
I don't use an SD Card, so the issue is resolved for me, however it is very interesting.
Could be Pressure or Heat (Small Hole Might Increase Airflow/Allow for Greater Dissapation or something)
Hi folks,
i've also small experience with this "white screen" issue and just wanted to inform you about it.
I got the device from my former boss who did already complain about this "white screen" issue on his O² XDA trion with original ROM. (honestly i did not really believe him due to my experience with couple of other devices so after i got the device i was just wondering - ok back to the facts).
I installed on Friday the Windows Mobile VI Pro - BLACK 2.5 Release and until today it was running (as far as i remember expect one time) nearly perfect w/o white screens. About 45min ago, i flashed the device with BLACK 3.0 Release and got until now about 5-10 times a white screen.
I assume this is not a hardware ONLY issue but indeed very strange.
I'll go back to 2.5 and will look forward if i get again the white screen or it'll be ok.
Cheers so far

You are right to ask the question "is it hardware or software".
1
We know a white screens can arise if folk duff up flashing a new ROM.
2
We know there is a hardware caused white screen that comes and goes often when device gets warm.
3
But there maybe white screens caused by some kinds of crashing software or a buggy ROM etc
Crucially in terms of finding a cure will be distiguishing between these.
2 for most people is easy - take it back and get a replacement.
1 is a matter for the ROM upgrading and fixing boards
3 is a case of trying different ROMs testing 3 party software by selective installation until the problem starts or stops.
In your case I am worried that this is a number 2 device as it did sometimes get the problem before you flashed the ROM and now it's worse. It may only be worse because this particular ROM is generating more heat and consequently more white screens. (see explanations elsewhere).
I suppose if it's an occasional problem you might live with it but otherwise it's replacement at best and repair as a rather dodgy alternative.
Mike
Hey Mike,
well, before flashing the device with a custom ROM, in my opinion it was really difficult to use it.
By flashing it with V 2.5, it was very good usable and with V 3.0 it returned to become more unusable. Nevertheless, i upgraded 10min ago with HARD-SPL-V7 and it's running fine now (i've been wating with downgrading to V 2.5. If it returns to become unstable, i will downgrade to V 2.5 again.
I'll keep you informed.
yes for this particular "white screen" issue it will be useful to hear how things go - thanks
Mike
White screen - in my case definitely a hardware issue
Hi folks,
i was testing and playing around with my Hermes and today i found the problem (very funny because now i can't reproduce it anymore but just read ahead).
Today i was playing around and after pressing by accident on the case of the Hermes, the screen appeared disappeared and changed into white.
Please download the video i recorded from the attached link - you'll see that it was able to reproduce it by tapping on the case:
http://asuka.descipe.de/dphome/test/HTC_Hermes_White_Screen_issue.mp4
Please use VLC or MPC (additional codecs required) to watch the movie.
Honestly i'm not sure if this can be reproduced by anyone but this makes the whole situation much more clear.
Any feedback is welcome.
Cheers
I had recently purchased this phone off of ebay when one of the screen alignment issues cropped up a few weeks later. Mine was the phantom tap in the upper right hand corner. If you do have this symptom do not bother with the business card trick or jam shims between the screen and the housing. I tried all that. Unfortunately AT&T would not grant me an exception to the non transfreable warranty - never hurts to ask - so I opened her up. The problem is definitly a mainboard issue. This is an interesting read http://forum.xda-developers.com/showthread.php?t=320775 For me, cooling the processor area when the sympoms were present made the phantom tapping stop. Unfortunately when testing this further, I misaligned the battery pack - doh! -this will kill the mainboard. I get a red light charging with no battery installed but otherwise it's unresponsive (and yes I've tried it all). As it was never going to work propery anyhow, I'll chalk it up to another unreliable batch of Hermes. This was a HT648.
So I'm going to part it out. The housing is in excellent shape. The screen+digitizer is in very good shape with 6 <1mm marks(4 in the perimiter and a 4mm airline scratch. Most of these occured trying to shim or gasket remove for the phantom tap issue.
Any part I can take off I'm selling. Just PM me.
I'm already, perhaps foolishly, in the market for another 8525, perhaps the at&t labeld ones have it all worked out....I refuse to do a 2 yr commitment with at&t, saving that for the 8925.
I have read many threads and forums about the problem of the Hermes becoming white. The soft reset in this case does not help.
I found the explanation in my case and I am not able to fix it quickly, without opening the device to screw the connector.
The problem is only due to the temperature of the device. When the temp is to hot, the screen is white, in my case, it typically happens when it stays in my pocket et I moving too much throug the office ;-)
Solution, simply open the keyboard and gently blow in the thin area between the two parts of the device.. in my case, the screen comes back in 2-3 seconds.
Enjoy !

To be honest, I have this problem on my 838 (wizard) previously.
I have found someone (engineer who I need to pay) help me to check.
It is actually the connection cable between the keyboard and screen start breaking.
This makes the connection poor.
End up, my wizard cannot be repaired and I have borrow my freinds hermes to use in the mean time.
I suggest you pay special attention to it.
I suppecm that you blow it is actually helping the connection of that cable.
huh
are you guys serious in what you're talking about?
blow in between the two parts of the device when it's hot to get the connection of the cable back?
are you sure you are talking about a mobile phone and not about a compressor?
thanks for your feedback. I am convince that in my case, the gentle blow does not move the connecting cable.
Additionaly, the tipical symptom reported in various thread is that the soft reset does not help, while letting it apart for 15 minutes does help. It can confirm that the simple temperature idea is fine.
Again, it works for me, it can help others, and sorry for the others that won't find a solution with mine!
actually, i am neutal to this topic.
But just want to share my experience.
In my case, my cable is aging. Initially, it can help with slide the keyboard open and close.
End up the engineer told me that cannot be repaired deal to no parts. he examined it using a microsope watching the cable.
no need to take it too series.
It is a cable connection issue, it is caused by either dropping or opening and closing the device numerous times. It can be fixed the part cost around $20 kinda hard to find but can be found if you search enought. I can repair the device if your interested either pm me or you can contact me at

when this happened to my hermes last August i found slightly unscrewing the two screws on the back of the screen fixed it & not had a problem since
didnt know what the white screen was 'till i got it right after the external volume crapped out, so tired of tinkering with hermes, going Kaiser
As a science experiment I have bought a number of hermes on ebay- it is a cable connection issue or worn cable in the 4 I have played with - all fixed by cleaning and reinstalling cable/connection or replacing the cable assembly. I cant say this is the only bug but 4 outy of 4 inducates a trend to me
John
Oh my gosh, topic starter, that is the same exact issue that I frequently have with my 8525. I eventually found out that if I leave it in direct sunlight, put it in my pocket for too long, or in anyway expose it to relative heat, then it would turn white.
That's a nice "fix" you have there hahah. As for me, I just let it cool down by placing it in a cool and shaded place, works like a charm after a few minutes.
Anyone with a WHITE screen MUST READ this!!!
To bring credit to what I say below, I haved had tinkering experience with electronics for the past 10 years, not to mention that I am currently a 3rd year electronics engineering student.
I currently have 4 hermes units.
When I first had the white screen prolem on my first hermes about a year ago (may be 8-10 months?) my research on the net revealed that the problem is apparently the connector on the button pad board (part number 50H000380-30M-A). After serious tinkering and tweaking I finally got the (extremely sensitive) connector connected up so that the white screen issue actually dissapeared. However, since the connection was so delicate and so sensitive, I had to fix it in place with a hot glue. Hot glue actually added some thickness to it; given that there isn't much tolerance between the top of the connector and the cover, I needed to scrape away some plastic without putting a hole in it so it can accommodate the extra thickness, this is also required for the sliding function to be smooth.
However, right now I have 4 hermes, and I am faced with the same issue. On two units I have the white screen problem. After some intuitive testing I have found that the problem is not with the flex cable, nor with the connector on the flex cable, nor the connector on the button pad board. The problem is with the actual button pad board itself, as it contains fair bit of circuitry on board.
This is how I came to the conclusion. Since the white screen can be fixed with sensitive alignment of the connecor on the board, I wondered if it will display anything with that D-pad (button pad board) disconnected. On trial, it didn't display anything on both a functional unit and a unit with a white screen issue. From this I made the assumtion that the LCD initialisation sequence is contained on the button pad board (part number 50H000380-30M-A).
Having made this assumption, I thought since the symptoms of having it disconnected on a functional unit is the same with a unit that has the white screen symptom, I wondered if it will fix the white screen problem if I changed over the button pad board. On trial, I found that the white screen problem was a thing of the past. So, I don't know what on the button pad board actually causes the white screen, but it is DEFINITELY the board it self and not the connector.
PS: I don't know the proper names of the components but by the button pad board I am talking about is the board that lies under the front buttons of the unit that has the call, end call, start, ok...etc buttons.
uengin, u totally had make ur homework regarding the white-screen-issue.
Anyway, for me, I face the exact problem too. And my way is much simpler. When ever I face the white-screen problem (this cause by the high temperature, coz I notice it only happen when I put my 838 on my pocket while walking during sunny day), I simply turn off the screen for a while (by lightly pressing the power button), like 3-5 second, then turn on the screen back. And, voila~ it back to normal.
i get a white screen when i press on the plastic casing on the lower right side of the screen, above the right bar button. no temperature involved here. sending the hermes to sleep and waking it up restores the normal screen.

There's actually a BGA chip in that vicinity on the button pad circuit board. It may or may not be that chip thats causing the issues, but I find it higly likely it is...

would you recommend to handle the hermes with great care? eg. not putting it in my trouser pocket because oft the pressure?

I doubt its a "loose" solder joint. It could be a dry joint. But then again you never know. However, the symptoms with the heating and cooling mentioned in the thread it could be one of the several devices on the button pad board failing due to heat.
As a general rule of thumb, definitely electronic devices of this calibre should be dealt with a level of care indeed.

uengin, u totally had make ur homework regarding the white-screen-issue.
Anyway, for me, I face the exact problem too. And my way is much simpler. When ever I face the white-screen problem (this cause by the high temperature, coz I notice it only happen when I put my 838 on my pocket while walking during sunny day), I simply turn off the screen for a while (by lightly pressing the power button), like 3-5 second, then turn on the screen back. And, voila~ it back to normal.

Same for me which seems software issue but how to solve it
I'm having white screen problem too. I highly doubt it has anything to do with a cable because:
1) I almost never use keyboard, aka don't slide open the phone
2) lately white screen often happens when I touch a screen.
3) several times white screen got fixed by holding the phone next to aircondition outlet.
4) white screen recently started at the same time I've noticed that the battery started dying, it doesn't last as long as before. Before this battery I had another one, similar, and also never had white screen while that battery was new.
To conclude all this, at least in my case is more likely it's a battery issue and/or overheat. Tomorrow I'll use the original battery (I've replaced it with 3k mAh 2 years ago) this should proof me right or wrong.
My white screen issues started after a waist-high drop onto concrete, accompanied by the D-Pad and the surrounding buttons not working. In order to get the white screen to go away and the buttons to work again, I have a simple 2-step process:
Put the Hermes to sleep
Press hard right above the D-Pad/below the screen
When I wake the device up, it works just fine!
Interesting Find......
I just noticed something about my white screens.
IF the poweron led does NOT turn on then I get white screen when turning on my hermes.
If the poweron led turns ON(lights up) when turning my phone on then it won't white screen on me.
guys - severe problem here
had my 8525 for 2 years or so and have had it insured thank goodness - two trips to the shop have been done already, one for the RED LED problem that i thought ruined my device.
now out of the blue yesterday the phone started shutting off on its own. seemingly randomly, at no specific times, it will just turn off, as if i held the power button down for 5 secs and hit ok.
it will only come back on if i hit the soft reset button or hold the power button and then it reboots. it is making life very frustrating as i'm missing calls and messages often because i have to constantly watch for the green LED to be on to know that the phone is still working
i have three accumulated three batteries over the years so i know thats not the problem, it occurs with all three.
anyone suggest anything before i send it back in? not excited to pay another deductible as i've already doubled the price i paid for the phone in insurance fees!!
My advice would be to do a complete backup, and then hard-reset. Assuming that the issue disappears after the HR, then restore from your backup. Hopefully, you will not restore the issue as well. If you do, then HR again, and DON'T restore from the backup ... install everything fresh.
HTH,

There have been a few reports that the battery contacts can become less firm against the battery - causing random switch offs. This was easily solved by having a thin strip of card between the battery and the casing on the side opposite the contacts. Thus pushing the battery a little more firmly against the contacts. (Also make sure the contacts are clean)
Something easy to try at least.
Remember to search - here's one example:

thought of that halfway through the day today when i was fidgeting with it and realized there was a little bit of play in the battery compartment. actually put a thin piece of paper on the opposite side of the contacts and the phone has stayed on for an hour so far!!! sure hope that was the fix - would make me pretty happy - keeping my fingers crossed!
i had done a hard reset last night hoping for a fix but to no avail. thanks for the suggestion though.
the weird part is no jarring or dropping took place so i am surprised this issue arose out of the blue??
thanks for the help - and i did search but will look more thoroughly in the future
Hope it works long term - I wonder if thin paper is enough, we'll see.
Sorry about the search comment
Cheers

Well, those spring contacts can get a bit tired and maybe a little oxidised and they loose the spring in their step - a bit like me really. I'm stuffing in the cream cakes however not slips of paper but I still randomly switch off from time to time, in fact more and more often!
haha - yea i suppose same goes for me!
however it stopped working =\ worked for about an hour and a half then i bent down to pick something up with phone in pocket and it died. seems like slightest movement would make a difference, but then later on it died at my desk again =\ thought i had found the culprit too
on the gold prongs, on the phone part, there is a tiny bit of evidence of melting on the black plasting holding the prongs. on either side of the black plastic where it meets the green board of the phones interior, there is a silver weld. on one side, it looks like the black plastic melted a bit and the silver weld is barely visible. the plastic is rough and not the same edge as the other side. that's the only noticeable difference
thought i had found a quick fix, but i suppose the last option is the old $50 deductible for the third time =\
Mmmm.. not good. However it seems it is a contact problem and there have been reports of that complete battery contact assembly coming off. Some have been successfully re-soldered, but in one case the contact was broken inside the mult-layered board.
I'm slightly puzzled about the melting - almost as if someone has previously been re-soldering it. (seems a little improbable that a poor contact at that ampage could cause enough heat to melt it - but I could be wrong)

mine was doing this and nothing fixed it apart from a reflash, its been working fine since i reflashed two days ago
hope this helps
I have been using AT&T 8525 for about 5 months now. Dropped it in office a week back and it was on an uncarpetted surface. No external damage but it powered off. I had to try for a while to power it on but eventually it did power on.
Since this event it just powers off on its own. Right now, even minor jerks cause it to shut down. When you pull the phone out of your pocket after a while, it has already shut down!!! Took it for repair to a local cell phone repair assuming it might have some connector damage but they could not figure out the problem. They opened it, cleaned the interiors (as it had dust build up) and according to them everything appeared normal.
What would you guys recommend? It is running Schaps 4.30. I see that HTC has a repair service in US.....had anyone tried that?
Sounds like battery might be a little bit loose... Jam something in behind the battery to make sure of constant connection... You're not the first with this complaint. The battey terminals may have been bent back just enough to cause this intermittant problem, especially when it gets jolted, the battery disconnects from the teminals causing an automatic shutdown due to no power.. Just thank god you didn't break the terminals off. Sometimes can be fixed but if the break is at board level, you may as well sell it off on ebay for parts because its just about impossible to fix then.
Cheers...
Very smart ultramag!! Your reply made me think what I did after it fell down. At that time I did think that the battery was loose as it was running when on active syn (powered by laptop) but not when I removed the cord. I did turn the terminals a bit and it powered on after few attempts (the drop must have given the circuitry some shock to recover after sometime).
I have jammed a paper on the side of the battery opposite the battery terminal. Will report back in a day or two if it still gives any problems. That should help others with the same problem.
Also this event has taught me that invisible shield (the plastic shield that we stick on) perhaps may not be the best protection. Case is a must to absorb the shock!
ok the problem still continues despite sticking a paper on the battery side (opp the terminal). I do believe that the battery was part of the problem. Before sticking in the paper, it used to give me a Red LED for few seconds when I attempted charging and then turned to amber. Now that problem is not there....it turns to amber right away on plugging in the device.
So part of the problem is addressed but the Hermes still powers down on its own when subject to minimum shock (in your pockets and you are walking around in the office or driving a car). What do you suggest? Should I send it in to HTC? Are they good about addressing repair issues?
... and yet I think it probably is the contacts as suggested above. It may be that it's a little more than just the contacts not pressing firmly on the battery though. There have been cases where a fall has actually broken/cracked the solder joints between the contacts and the board. A trickier thing to fix unless you have some skills in that direction.

AT&T powers off after drop - HTC's take on the situation
Ok so here is HTC's evaluation of the situation.
They want to change the main board (mother-board I guess). In addition, though the phone is just 4 months old (was purchased refurb from AT&T) and has barely any scratches, they would replace the casing, the keyboard and the structure that holds the keyboard and LCD. And they would ONLY charge me $272. Isn't that ridicuously amazing??
To me it seems they can't figure out what the hell is going on, so lets just go ahead and replace a bunch of things and one of them should be a hit.
I have asked them to send the phone back. Mike, do you think the main-board could be the issue? Any recommendations of who I could try for repair.....or what I should ask the repair guy to look into to find out if the main board is the issue or not?
Only $272??? Good God! That lot would cost you around $450 if it were fixed at HTC UK!!
If the drop caused cracking internally then that may be why they want to replace the rest. if there are known defects that are not repaired, they cannot guarantee the repair and so will not do it at all if you do not agree to the whole thing.
of course, you could be right and they have no clue and simply want to replace everything and hope something gets fixed....
Don't PPCtechs also do repairs on that side of the pond?
