White screen? - 8525, TyTN, MDA Vario II, JasJam General

I have an unlocked Cingluar 8525 (TyTn) I have had it for like 5 months now. Upgraded to WM6 as soon as I got in in July. Recently it has started slowing down and lagging a lot. So last night I restarted it cause it froze. When I did that it would freeze on the WM startup screen. So I rebooted while holding the 2 soft keys and then clicked yes to restore. That worked. Then today the phone fell off the arm rest of my couch onto carpet and I went to go send a message and it was all white. So I restarted and now everything is just a blank white screen, no startup logo or nothing. Has anyone had this problem before? I tried resetting it again and it didnt work. I have tried turning on with no sim card and same problem. Anyone know how to fix this?

It is all too common,
I've been told it is due to a loose connection between the ribbon that attaches the screen to the mother board.
I think its a design fault - the ribbon is linked to the two parts of the Hermes (screen and keyboard) and surely all that opening and closing is essentially moving something that is designed to be a static item. This I think weakens the ribbon connection, causing the white screen of death as I've nick named it.
Here is a link to dismantling the hermes to reconnect the ribbon.

Though you should know I attempted this tonight with very little success.
I still have the white screen issue. Its very frustrating that the reason I bought this phone (the slick keyboard action) is the reason I cant use it anymore.
Hope you have more luck that I did, Let me know...
PS - If you have never taken it apart before (I did to replace the screen) It should still be under warranty - or if yours is second hand - you could send it to apex laptops for repair.

Help! Stuck on Align Screen!

Guys, I hope you can help me!
I was using my Imate Jasjar when it was accidentally bumped by another person. the Jasjar fell but it wasn't that high and the floor was carpetted. However, I noticed that whenever i try to tap on the Start button on landscape mode, the calendar application opens up! And when I try to tap V-Bar on the other corner opposite the Start button, the Contacts application opens up. Basically, the soft keys on the bottom screen are the one opening up even if I'm tapping the ones on top! If I tap the bottom soft keys, I thought the Start button or my V-bar would come out but still the Calendar and Contacts applications were the ones that opened. Basically the everything on top cannot be tapped!
On Portrait mode, I can tap the start button but when the V-Bar was tapped it still opens the Contacts application.
I went to Settings then Screen to re-align the screen. I thought it would solve the problem but apparently it didn't! I was trapped in the Align Screen section giving me an endless loop to tap the 5 areas of the screen.
I now did a Hard Reset, and now I'm forever got stucked to the Align Screen part.
What am I supposed to do??? Please help!!!
Hi,
Seen the same problem... Try to guess the error margin of the alignment...
for example instead of tapping in the center of the cross try tapping on left or right... Since your screen isn't aligned you can't press on the center...
Now the problem is hardware, not the MB but the LCD...
After tou figure out the margin error, the Universal will resume and then you ca align the screen via Start->Settings->System, align screen
I'll try to know more about this problem asking my friend.
Best of luck
thanks for your reply!
i also believe that it has something to do with the LCD. there are no cracks whatsoever. problem with the aligning is i have to keep on guessing. and if ever i do align the screen successfully, i'm not sure if re-aligning the screen in Settings would solve the problem.
i would appreciate though if your friend or anybody else can shed light to a solution.
This is a simple problem to solve ;-)
When the allign screen is ON and you have to make the first tap on the crosshair (just before you start clicking away to allign your screen), twist your display from landscape to portrait mode...
Now continue to allign it as usual, and you should finish successfully!
Cheers,
San
unfortunately, after following your instructions, i still went on an endless loop on aligning the screen. i'll try to reflash the rom and see if it would work. i hope it does...
i updated my ROM. still stuck on the alignment screen!
any more ideas?
To be honest, sounds like your screen is broke. Even if you got it to align, I doubt it would be very usable. I think you are looking at repair - if there's no visible sign of damage, you might get away with a warranty repair.
Cheers,
Steve.
Hi
Few months back i've got exactly the same problems (odd LCD behavior, impossible alignment, etc...) with an HP4700. I went to the service center and they had to replace the LCD screen. They did not charge me and take it under warranty. In my case the unit did not drop and i made it clear to them. I would suggest you go back to the service center and forget about the drop in your problem description .
Cheers,
Bruno
I had the same thing happen on a HP 3700, I did not even drop it all i did was install the Quake game for it and after a few days the screen alignment went a bit out. It was usable but definately out by about 1 cm in each direction. The unit had not been dropped. I went into the allign screen utillity and ended up in the infinite loop. The only way to fix was a new screen. But unforunately it was no longer under warranty. The screen consists of 2 separate parts the lcd and the touch screen bit. In my case the lcd had no issues just the touch screen. Very annoying but there you go.
Search your soul and do what you feel comfortable with.
Good luck
Charlie
thanks for all your replies!
i've made several searches yesterday with similar problems (even if they're using different PPC models) and they all ended up sending back their units for repair. there's even one who posted in expansys with the same exact problem!
we'll be sending it back through expansys (we got the unit from them) and hopefully get it back before the end of the month. and yes, i won't tell them that it was dropped, he he :twisted: and they won't find evidence either on the outside because there are no physical damages. what a start of the new year for me <sigh>
right now i'm back using my XDA IIi.
thanks for all your support! this is my first thread/topic in this site and it's so unfortunate that it had to be sort of a negative one. looking forward to be active more here!
Hello there
This might help (I am currently wrking with 200 PDAs so have had this a few times)
THere may be a iece of dust/biscuit crumb etc, under the edge of the casing above the screen, try using a post it note or paper and go around the casing/edge of screen, this should clear the screen of anything that may be causing this problem.
THis worked for me on the majority of non-aligning screens
HTH
DB
My story was, one day when I needed to twist the screen, it was a bit stuck so I twisted a bit harder, yes it went back. Then few days later, the mis-alignment started and since then I have been keeping to do re-alignment my screen.
My screen is mis-aligned once every 2 or 3 days or even few minutes then I have to re-align by using WM5's alignment program. It sometimes takes me 2 or 3 times or even one time.
The most anoying thing is it keeps forget after aligned screen.
Now, certainty, I don't think it is a screen problem because after running alignment app, it correctly pointed into the right spot but then it forgot where the right position was.
I have done the upgraded ROM ( even tried Ivan AKU 3.2 ROM ) but problem still persisted.
I just tried clean up the edge of screen, finger cross, hope it fixes my problem.
Bad thing is, I bought my device from UK and I am living in Australia so therefore, my warranty is definately invalid. I don't want to spend 200 AUD for the new screen ( unless I am 100% sure that LCD is faulty ).
Anyone has any idea or even a better suggestion because I don't see many people having this problem.
I suspects that maybe the flex cable got ripped but not totally ripped. Don't know , please help me out on this one
Best regards
Anyone has any idea about my problem ??
One question :
I know that the flex cable has 2 connectors ( one is for LCD display and another is for LCD function ). Now does LCD function relate to the touch screen function ? and if one tiny wire of the function cable got cracked, but not totally cracked, will it affect the touch screen function ?
Other thing, does WM5 store any setting relating to screen alignment setting ? If yes, where is it ?
Thanks
Hi, from another forum, it only help to bypass the alignement loop:
"here you go theses are simple steps to bypass the touchscreen alignment.
Install you activesyn blah blah blah when it finds it go on my computer and go into your PDA device
go to windows startup and delete the Welcome file
after that give your PPC a soft reset and BAM u by passed the screen now get a free desktop program liek pocket controller from the internet it will automatically install on your pda and BAM you can control your pda add music and whatever
but now if you want to click stuff on the road get pen irazu just search on google and send it to your PDA then go to file explorer and double click it and you got a cute little mouse program that you can use like a stylus"
also try this little soft:

Hi godtakeit!
I've had the same problem a few weeks ago (and still having it from time to time) and for me a slight (very careful) bending of the screen makes it work again. It seems to me that there are connector behind or near the display which has some loose contacts.
Did you notice any other problems which came in conjuction with the alignment problem (e.g. speaker not working)?
.ox
Hi oxident
No, I don't have problem with speaker ( it was not working before but it is because of the jack plug problem - it solved ). Yeah, I did notice if I bend the screen carefully, the problem is gone. The funny thing is when I aligned the screen, it worked but if I closed it off and left it over night, it started again when I opened the lid.
You may right about the connector between LCD screen and mainboard. Well, I have no choice but openning the device and check it up.
Also, I read the thread somewhere in this forum and somebody advised this problem maybe relates to magnet around device. My brother aslo advised me that LCD charged and reserved negative electrons. Wierd but I am experiment it at the moment ( taking off battery and leave the device for a few days so that it can release the negative electrons ).
Hope it fixes
please help
i have an imate jas jam that i i got from my father he used it for like 3 years and it is pretty banged up so i cant use the warranty and repairs cost a lot, any who i got it yesterday and it was very slow so i reset the settings and now im stuck on the align screen it keeps going on for ever and ever if any one knows any thing plzzzz help

8525 Touchscreen Has Gone Crazy

Ok so my Cingular 8525 is basically unusable due to the touchscreen thinking it's getting taps in the upper right corner (upper left in landscape mode). This has the nice effect of closing programs down to the today screen in portrait mode or constantly popping up the start menu in landscape mode (about three times a second). Any ideas?
I tried soft resetting and also removing the battery for several minutes. Haven't tried a hard reset as I don't want to go through that except for a last resort. Tried wiping the screen with a soft cloth. There are no weird programs on the device except what everyone here uses.
I still have 5 days before the end of my 30 days return period with Cingular. If I bring it back will they just give me another one?

on your touchscreen problem.. i have seen this occur by someone improperly putting on a screen protector or maybe there is some dirt up there.. and if you take it back to the store they may give you a new one or make you call the warranty by mail line and get a replacement that way
..... or your OK button could be stuck down
I took a bottle of lens cleaner from my camera bag and thoroughly cleaned the screen. I ran my fingernails under the edge of the screen and really made sure no dirt was under there. Lo and behold, it seems to be working fine now. I browsed some RSS headlines for about 10 minutes with no problems.
Weird though, I have used an Ipaq 4705 WM5 pocket pc for two years now and really ran it through the ringer. It looks like it's been to war and back (which it has in a since) and never experienced errant screen taps. Oh well, still enjoying the 8525 (last phone was 2125).
Thanks so much!

Just a note of caution!!! This is related to the screen alignment issue i.e. the touch sensitive area of the screen continuing beneath the bezel and causing unwanted touches whether through dust or the sticky gasket in there.
May not return, or will be cured again by the "business card" fix / or as you did a firm clean to release the screen from touching the bezel.
But, it's a question for you, if you only have 5 days left under warranty. Most people with the SA problem find the first signs appear in the first couple of weeks. I would certainly put it through it's paces, open up a few applications leave wifi on so it heats up, surf web over wifi etc etc as the added bit of heat generated internally was a known factor in exacerbating the problem. If all stays well over next couple of days maybe it'll be OK.
Would be good to get urgent feedback from anyone with a newer Hermes who's had this issue and what happened.
Mike
Argh, it's back. OK, I'm certain it's a touchscreen problem and not a button sticking as holding down OK will not cause the start menu to pop up while an application is up and holding the windows key will not close an app. Also the problem is delayed if I hold the stylus down on the screen. It's just the upper right (portrait mode) of the screen that is getting the errant screen tap (about three or four times a second).
I've ran a business card through the edges and it doesn't help. I'm not going to take this thing apart. I did that several times with the 2125 to fix unresponsive keys and joystick but the problems always reappear. My one year old 2125 is barely functional now. My g/f would rather keep her crap LG flip phone then inhieret the 2125 after watching me battle it. That's pretty sad.
I'm going to try a hard reset (second one in three weeks) and if that doesn't help I'm returning it to Cingular and getting my money back. Then I'll either buy another one or a blackjack. I like the 3g and love this device. It's my third Windows Mobile 5.0 product. I don't like the sub-par build quality on my second HTC product now. I paid $599 plus tax for this phone at a local Cingular store (despite the web store saying $550).
My advice for what it's worth is take it back. This screen business has a habit of coming and going and it's entirely possible you hard reset and everything is fine and two weeks later it's back. Also would be better to return with the issue present (not that they wouldn't believe you -would they?)
On the whole though this problem is much more rare than it was, so if you do get the same device again hopefully you will be luckier. If you get directly from shop though check the firmness of the key board clicking into place that seems to still be fairly common problem.
Not the best start to the new year!!
Mike
Well I got desperate and hard reset... I could barely get past the screen alignment startup so needless to say that didn't fix things. Having gone this far and thoroughly pissed at having to reinstall everything I decided to loosen those screws on the back and run a card around the edges.
So far, it's working! I'm not content settling on this hack though so I'm bringing it back Tuesday and will update on my experience at the retail store (not looking forward to that).
Happy new year and thanks for all the super fast responses guys!

I was browsing the www the other day and saw a korean/ japanese site showing the inside of these precious devices, and (as pointed out above) how the seal/ gasket underneath the bezel is the root cause of our anguish.
There were some detailed pics of how you can DIY, and remove the gasket, but it's no where near me basic level of competency.
Why would they design a touch-screen to big for the device I wonder???
there is also the business card trick about sliding it underneath the edges to loosen the gasket... there is a whole thread on this screen alignment issue
what site shows how to fix the gasket?
There is a post about someone seeing a site showing how to fix the gasket proplem on the touch screen. Could I please get the URL??

Just got back in from my local Cingular store and actually had a pleasant, hassle-free experience exchanging my 8525 for a brand new one. I explained to the CSR the issue and she immediately understood the problem (must not be the first guy walking in there about this).
Unfortunately, she didn't have any in stock but merrily called around and found six others in stock at nearby stores. So off I went to the next store and had the old 8525 exchanged for a new one in less then ten minutes. The CSR didn't even bother to look at the old phone or check the accessories I returned with it.
The new 8525 is syncing up as I write this and immediately I notice some things are different. First of all, written on the side of the box is 12/26. So we know this phone is probably brand new. The keyboard does indeed click in and out more firmly then my old one. The USB cable plugs in tighter (a good thing, I was always getting USB connection problems), and lo and behold Windows Vista installed HTC sync drivers then Media Player automatically recognized the device (never did any of that on the old one).
I'm using the Windows Mobile Device Center Beta on Vista RTM and it just finished syncing without any problems. Moral of this story is if your 8525 is experiencing any problems at all and you are within 30 days, return it for a hassle free refund.
Good news and you're absolutely right about getting it back within warranty if there's a fault.
Great stuff!

Cingular 8525 touch screen no working
I am having a problem with the touch screen on my 8525. My phone was working fine then the then the screen stopped responding. I was able to navigate via keyboard but that was it. I did a soft reset and it did not help. I then did a hard reset and the screen went to the setup and wants to align the screen which obviously I cannot do.
The changes I have made the same day prior to it not working are as follows:
-Unlocked with Hermes SIM Unlock
-Installed latest Cingular ROM
-Installed fit4cat Hermes Tweaker v1.1a
The phone worked fine for about 12 hrs before the touch screen stopped working.
Any suggestions?
Hey there, I have had the problem before (about 3.5 weeks ago). I had to send it in for service (since I am not a Cingular customer anymore but use the 8525 with T-mobile).Good luck.

8525 White Screen of Death - Is there Hope?

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
http://inuchanbt.blog54.fc2.com/blog-entry-100.html
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.

fixed my wsod
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!!

"Half-bricked" trinity after lcd broke - bootloader still working

Hello,
I'm facing the following situation:
I droped my Trinity and the LCD broke on the left side pretty bad. It booted fine after that (the LCD was still visible on the right side) but after 10-15 seconds it just froze. The hardware buttons were not working, nor the touch commands. I could only rest the phone with the stylus.
I successfully replaced the LCD by myself and now I'm stuck with the freeze. I was hoping the freeze will disappear but I have the same symptoms as before.
I tried a hard-reset but after that the phone froze during the booting process with the logo on the screen.
I entered the bootloader and connected the phone to the PC. It worked just fine and the freeze didn't occur anymore. I uploaded a new ROM but again, during the booting process I got the goddamn freeze.
I was hoping that everything beside the LCD survived the crash but I'm starting to have second thoughts.
I would appreciate any advice or hints on how to find what could cause my problem.
Thanks
If its freezing up on you then I would imagine you've caused some hardware damage.
Like you, I would have hoped that replacing the broken LCD woudl fix it, but there's nothing to say you havent partially damaged or dislodged something else, especially if it was a high-impact drop...
PS
I wouldnt try doing any more uploads to it either if I were you. If it freezes up during one of those then you could end up trashing the program area of your device too!...
Hi guys,
I had quite the same problem, without braking the lcd but anyway it fellt from a airplane onboarding bridge :-( and then it has started to randomly freeze.
I think I may have found something. I've noticed that when I press strongly the battery it's not freezing anymore!
I've opened the phone and saw that under the little metalic protection's plate there were a contact plate between a little black component and this metallic protection'splate. I've cleaned it, apply some thermal past (like cooling artic) and the I've put a little sheet of paper between the plastic frame and the metallic protection's plate. I've all remounted.. And surprise!!! not one freeze since two day!!
I hope it will last.. but if yes this s F### great
ähm.. I release any kind of responsabilities concerning this action. I'm not a professional but as soon as it has work for me I wanted to share it ;-)
Seeeervus!!
Dodjob.

Help with diagnosing LCD problem

Do I blame the onboard video or the LCD itself for this problem? I've taken the phone apart and re-seated the motherboard connections, which was no help. If I connect using EveryWAN the phone appears to be working fine, in fact I flashed the T-Mobile ROM and than the Button ROM thinking it was a IPL/SPL issue. Even if I try to start in boot loader mode the screen still looks the same.
Just trying to decide If I need to replace the motherboard or the LCD.
Thanks,

Screen seems intact without any damage visible, no cracks or out?
Had this problem once with my old Universal, was the colour transfer wires that were loose, but pretty sure the Uni is totally different to our wizards.
Prehaps open her up and see if theres anything thats loose prehaps.
I had it opened and re-seated both the connecting cables, but no luck.
Ive had this problem with my wizard .. i couldnt find a solution. tho i didnt really try very hard. Basicaly just picked up another one on ebay for like £30 seemed cheaper than spending the time and effort fixing it. I think mine got progressivly worse. It used to do it occasionaly and now just it as soon as its switched on
i have a same sort of problem...
left of the screen fills with lines and the whole screen fades to white.
turning on and of the screen via power button takes it back to normal but then it happens again.
noticed it only happen in portrait so i have to set it to landscape all the time
for some rom and spl's it happens just a few times a day and others i cant use it in portrait.
If i find a solution it might be working for you to
Fading white screen of death
Could be the battery. Have you tried a new battery?
Solved.
The LCD itself was bad.
