I need help...
My T-Mobile MDA can power up but it will just stay on a white screen & after awhile, the backlight time-out & swtiches off.
Tapping the screen or the power button will bring it back on.
All the buttons seem to be responding & the system sound comes on when I press some buttons.
What might be wrong?
Several soft reset will not bring me to the standard screen.
Is it a hardware issue or software issue?
Please advice me what I should do to recover from this situation.
Thanks!

Update:
I finally performed a clean reset & the standard WM5 "tring" sound came on.
At least, the system board is working fine.
But nothing appeared on the screen except for the greyish-white background.
I also brought the MDA into the bootloader mode but I don't see the Tri-colour screen.
What should I do next?
I noticed from the MDA Service Manual that there's a flex board for connecting the screen/front panel buttons to the system board.
Could that be cause of my problem? Or is it the LCD screen giving me problem?
Please, anyone who has experience with this issue, I appreciate any help I can get.
TIA!!
Is your MDA out of warranty? Do you have insurance? If no and I were you I would probably take it apart and check for a loose or bad connection. You got the service manual you should be good to go.

bendog2784,
My MDA has no more warranty nor insurance.
I took the plunge & disassembled it.
I made sure all connections are clean & tight before reassembling the unit.
The screen still stayed greyish-white.
This morning, I screen suddenly turned on but for a brief moment.
It seems that when I slide out the screen (or slide out the keyboard), half way through when 2/3 of the k/b is exposed, the screen looks just as it should.
Beyond that it will blank out, kinda like a device having been put to hard reset from an operational state...except that the backlight stays on & then greyish lines start to appear.
So now, I'm not sure if it's the screen that's causing problem or the flex cable.
The flex cables are very hard to find where I'm & very costly too, judging from eBay auction listed.
Would appreciate any help to revive the screen of my MDA.
Thanks!

What happened to your LCD that prompted you to replace it?
Did it crack?
If mine was cracked & there were fragmented display showing through, I would have gotten a replacement LCD with no questions asked.
However, in my case, the LCD is not showing anything other than a greyish white shade no matter what I do to the hardware.
I'm not sure it is a LCD problem as I mentioned above that yesterday, I got it to work for a short period of time at a certain position.
That said, I can get a replacement LCD for my MDA for less than US$25 here.
If it is an intermittent problem (as you described) I'd check the flex cable again.
try to reseat the connector that goes to the LCD (the large one that is locked in place with orange tape and the little brown clip on the connector itself).

There are at least two multi connectors for the screen, one from digitizer and one to main board - so it's entirely possible screen is still receiving power but not signals from main board. That's not to rule out something more drastic but hopefully that's all it is.

Hi Mike.
This is my first post as I've so far managed to cure all my issues from just reading the forum. However, I am now having a similar problem with the white screen.
I have a cingular 8525. It fell, the following day the call and end buttons remained lit and wouldn't turn off, they also wouldn't work.
I soft rest, nothing, I then removed the battey and when I turned it back on, there was a white screen and the buttons below still don't work.
I have read the other posts on this issue, but I need help on exactly what kit to buy to reconnect the screen cable and instructions on how to do it as I've never taken apart a phone before, although I have dappled with other electronic devices.
Your help would be much appreciated, as I am in Jamaica and there are no technicians here who I trust to help.
Thanks in advance.

Ok so I have the fabled white screen issue on an 8525. When it first occurred I searched and read all the write ups, decided I had the ribbon cable issue. Took it apart and simply unplugged and replugged the ribbon cable with great results, no more white screen.
I repeated once when it came back after being bumped around, again with positive results...but this last(3rd)time instead of it working I now get white screen 95% of the time. I re-notched the sliders the first time, and last time.
During the 5% it works I noticed the charge light would correspond to it going white.This never happened before...
Example:
When OFF - Connect charger, Red light for 1 second, then nothing=White screen from power on
When OFF - Connect charger, Red light for 1 second, then orange charge indicator = normal startup
When ON and Working - Connect charger, no light, no charge - reboots to white screen
When ON and Working - Connect charger, orange charge indicator, reboots normally.
There is no heat or noticeable pressure on any parts, everything seems to fit normally.
It does boot normally with screen white.
Any ideas? I really don't want to give up on this thing, is there any hope? or just ebay it for parts?
Thanks
-Nick
same problems here, if someone could just tell me what parts to order, cause I have no warranty (ordered over ebay). I tried both the instruction that has chinese fonts on the page , and other from R&R, no luck, white screen all the way..
I had the WSOD and took it apart and reassembled a few time. The 3rd or 4th time the screem came back, but now it is shifter to the right around 1/4" or so. I mean there is just white along the left edge, then the normal screen/color starts and is cut off on the right.
Does anyone know how to correct that, is it related to the same flex cable or is there something else I disturbed?
mine will fade to white.. then i just push the power to put it in standby, then push power again to wake it back up and back to normal.. it rarely does it but still annoying...
If You Ordered From At&t
I had this problem about 2 weeks ago!!!!
I thought it was a fluke!
Anyway, walked over to 43rd and Lexington (NYC FOR THOSE WHO DON'T KNOW THAT MANHATTAN IS THE CENTER OF THE WORLD)
and they gave me the EXCHANGE HOTLINE for at&t.
I called them up, told them my screen is fading to WHITE and the lady sent me a new or referbished phone.. i dont even know.
Just so you know, i ordered my phone on AMAZON with a new activation. its covered under the MANUFACTURERS warentee for a full year from the date of purchase... so is the REPLACEMENT PHONE... but not from the date of replacement, just the date of purchase.
did anyone get deeper into this yet? I got a 8500 (need those without camera) from ebay USA, already with white screen. After reading here, that this is mostly an issue with connectors, I bought it, disassembled it and reassembled it, though still white. Should I give the contacts a treatment with contact-spray? (there's a tuner spray that doesn't leave residues) Or is there something broken within the ribbon cables? Seller said it has been dropped (but he also said, he didn't want to open it, while it clearly has been opened, one screw missing and warranty seal gone). It ssems to boot up normal otherwise, I hear a sound after the boot process, so probably this isn't a software issue?
Edit: another thing I noticed: When I run it without any keyboard connected at all, it's also white. I then connected the dpad again, and I could see a hint of the at&t logo in the lower part of the screen. When I pressed around on the back of the dpad a bit, all LEDs would go on/off... Sound to me like the dpad has gone bad, possible?
Edit II: Got it. Using a 20x eyeloupe I found that the PCB of the DPad is broken under the little chip on it. Now I just gotta find a dpad here in germany, but I assume those Hermes' are all equal...
hello
where can I get manual (if there is one) for disassembling hermes. link in wiki does not work.
thanks
this worked good for me

Anyone know if this applies to the 8125 as well? I've got a flickering white screen. I had dropped my phone a few weeks back and cracked the LCD. Replaced it with an OEM LCD - it worked fine for about 2 weeks and then just suddenly went all white. Phone still works, I can still get calls - just can't see who is calling.
I don't recall that the wizard had the same problem... Though from a logical point, it seems that there is an issue behind white screens and the thumbpad being responsible for it, so it may well be the same thing. Perhaps just disassemble the wizard (there should be a howto too) and check if theres a similar connection from mainboard to thumbpad circuit.
Is there a disassembling manual for a imate k-jam that anyone knows about?
Here's a website with a video manual i found useful...
http://viralelectronics.com/category/howto/page/2/
Figured out the problem...
The only reason I figured out the screen goes blank is because the motherboard loses connection with the screen when you slide the keyboard out...try this out and see if the screen comes back...
put the screen on sleep mode (no white screen)...then slide out the keyboard and tilt it a little hard after pressing on the screen and put the power on. if it doesnt work try again it might take some pressure and power to make it work...be careful not to put too much power but as far as I went, it's a very sturdy cell.
alternately, slide out the keyboard in sleep mode, and press all the buttons really hard and then try to press the power button (press more towards the space bar because that helps)...if any of this works and the screen comes back on even just for a second...follow the following
Go back to the person who gave the link to the site with opening the HTC instructions and follow through and clean the whole phone up from dirt around the screen and such...you dont need to put those rubber things or whatever it says to put on the screen...then when you are putting it back together, press hard on the wire connecting the touch screen to the motherboard. I suggest sealing it with a good tape...and then you are good to go! I did it but it had a few glitches...the screens contrast sometimes goes awry but it is still visible and responds to touch. Also, the physical buttons work as well!!
Good Luck and do it at your on risk.

I noticed a few days ago my 8525 screen went white, rebooted and it went away. Today it came back, but would only go away for a few seconds and then back to white. After reading some forums I decided to check the connector. I took the phone apart following this site as a guide. I removed the connector on the board side and cleaned the contacts with a qtip and denatured alcohol. Phone has been perfect for the last few hours, no more white screen of death. I didn't mess with the connector on the LCD side, just the board side. I'm a computer tech and I found it quite annoying to disassemble, but I managed without causing any damage, however, I'd rate the job at about a 8/10 as far as technical ability.

i agree that this is one of the first things to try in curing the white screen issue. Others may find their problem runs a little deeper and the contacts on the d/pad chip are broken. An improvised cure which may not be very permanent is to place a little padding on the surface of the chip as described here:
http://forum.xda-developers.com/showthread.php?t=321163
If you have appropriate heat gun equipment you can re-flow the solder on the d/pad daughter board - but remember to remove the sticky key pad layer or you'll cook it!!
I regret that I'm closing this thread because we have several "White Screen" threads and the questions and answers are being spread all over the place.

Dear friends
After opening my Hermes a few times I encountered the white screen, I disassembled and assembled again, the display was completely off. I thought the flex cable could be wrong. So, at first I tried to use a soldering gun to seal all solderings (Photo 1). This time the phone showed a part of display. Because, the symptom was not the same, I guest contact between the flex cable and the mainboard had problem. I used point of a knife (make it blunt first) move down to push contacts out (Photo 2). Then I assembled my phone, everything returned normal. (9h in the morning to 11h in evening to make my heart cheerful again ).
I write my experience here for someone who open their phone and encounter the symptom like me.
Good luck.
Sadly didn't work for me. Stil no backlight!

I had a problem with no backlight but fixed it when I replaced the flywheel. I was trying to update a replacement jasjam I'd bought off of ebay but when I replaced the new flywheel with the old the backlight wasn't displayed so I tried the old motherboard with the new flywheel and the backlight was on. I don't know how it affects the backlight but it did. If you can get your hands on a cheap bung phone or have a REALLY trusting friend then try that.
Cheers...

Sorry mate, what do you mean with the flywheel? English is not my mother language and what I have found in the net for that word does not mean anything to me. Can you provide me with a better explanation? I do have the same problem as the guy which writes above you.

The little wheel on the side of the Hermes. I replaced the board That has it on it and it fixed the backlight issue.
I need a replacement windows PDA phone for my lost wizard... and i have a friend willing to sell his 8525 for $50... the downside...
according to his is... his touch screen works half the time.... something about working on a full charge... or not working on a full charge... and when its halfway charged... it does the opposite... etc etc...
he said the screen lights up just does not respond to the touches under the above mentioned conditions.
i did a search over here and HOFO.... and have noticed alot of people have problems with the top right corner of the screen (portrait) being stuck and closing out apps.... or launching the start menu repetedly...
and there isnt really a fix?....
is 50$ still a good deal?.... will a replacement screen and digitizer fix it?.... which is around another $50 i believe?
or should i buy one from ebay... they are selling for around 170-200$ shipped.... or is this a problem that plagues all 8525 hermes eventually?.. and i shouldnt bother with this model... and go back to the wizard or get something else?
The Hermes is a really great phone (I passed on getting a Kaiser, as it didn't offer enough of an upgrade), but I don't know if I would personally buy one in that's having issues like that.
50 bucks isn't bad, though. I might bite for that price.
I've had no screen issues over the last 1 1/2 years. I just saw a used 8525 sell for $181 on ebay...it's a great scalable device!
Alright.. i got a hold of the phone.....
everything seems great.... touchscreen was working... but as soon as i went to charge the battery.... and took it off charge once it was filled up to 80%, the touch screen stopped responding...
and i also did a hard reset ... and the screen still isnt responding.... and i cant pass green setup screen that asks me to tap the screen to continue.
any way to bypass this screen?... i dont mind using the phone with only the buttons...
and do you think this is battery related?.... the prev. owner said something about... leaving the battery to cool over night... and pop it back in... and touchscreen should respond again....
any suggestions?... thank you.
Find the program "Remote Screen Alignment". If you can get the Hermes to screen alignment to work, you can save the settings to your pc then if you reflash an os or have to hard reset you don't need the touchscreen. Try taking the battery out overnight and see if you can do the alignment then. Once past the screen alignment you can operate the Hermes using the buttons BUT you need to first get past the alignment settings.
Alternatively, if you know someone with the same Hermes you can get the Alignment settings off their phone. You need the above app.

"please tap the screen to continue etc etc"
will that program help me get past that?....
and the battery is out of the case right now... and im in school..., hopefully by the time i get back home it should work.

well... i see that you live in the UK... it might not be favorable purchasing it from you...
and tihs ribbon cable that you speak of.... do i need one for the isntalation of the screen?... and the one you have isnt made for this phone right?
Alright guys... so pretty much what the previous owner says checks out..
the phones touchscreen started responding to touches on a cold battery that was sitting for a few hours....
as soon as i begin to charge and the batter warms up... or the phone warms up.. im not sure... the touchpad stops responding.
ANY SUGGESTIONS?...
is this an issue with the battery or the touchscreen?...
aside from that.... this phone is fantastic!
Hi there
I am in the UK, and the screen has in fact been removed from a cingular 8525 i cannabilised for the d-pad board, the screen works perfectly and the ribbon cable will of course fit your phone.
I am willing to ship to the USA, and in fact i regularly do, only recently i just sold a little rubber dust cap for the hermes on these forums and its on his way to him right now. if you can pay via paypal your more than welcome!
Not the battery. The battery only supplies power to the mainboard and through that to the lcd. If the battery was at fault then you wouldn't be able to start up. It sounds like you may have heat problems with either the lcd ribbon or with with the flex ribbon connecting the top part of your phone to the mainboard. If I was you I'd check out Mike Channon's site as he is the MASTER of Hermes hardware and if you don't find a solution you can PM him. Heres a link to his site - http://michael-channon.spaces.live.com/

id buy it and sell the parts on ebay
Ok I need help from the gods of xda
I dropped my tilt the other day. When I picked it up everything seemed fine, yet the screen was completely white. No signs of cracks or a broken lcd. So I've tried the following: Soft reset, Hard reset, took out the battery, took apart the phone and disconnected the lcd and then re connected it. Still the same problem. WHITE SCREEN!
I can still receive/make calls, when i touch the screen in places where i remember the menus to be it still responds due to the noise, also the open and close noise still sounds.
The phone was bought new on Ebay, so i don't have a warranty through them or AT&T. After much research I hear people saying the same has happened to their phones as well and that there is a ribbon or flex cable problem. Something about still giving power to the LCD but not data, thus the white screen.
Now what I dont understand is do I need a new LCD because it has that ribbon/flex cable on it???? (link)
or
Do I need this product?(link)
Both contain a "flex cable" so im confused and frustrated, someone please help! any ideas would help

I am curious about this as well. I have a friend who has a hermes and he mentioned to me that that his screen was starting to go white like explained here. I look at his phone and I also noticed that the bottom hardware keys were not working at all.
I am wondering if this same ribbon cable for the LCD would also be the same one for the bottom keypad and if I fix the screen the keys will become active again.
Anyone have any experience with this?

Tuck in for a long read and perhaps no single answer for all cases:
http://forum.xda-developers.com/showthread.php?t=303872
In short, yes the d/pad cable and LCD screen connections are linked which is why it is not uncommon for the white screen to show up when the d/pad is not working.
To the OP - I would just point out that if you get the white screen after a fall it may just be a loose connection at the d/pad and no need for new parts.

But let's not start discussing the white screen here, please use the first link I gave above if you need to post.
