Screen Turns White When Opening To KeyBoard - 8125, K-JAM, P4300, MDA Vario General

I have a MDA and i got it from a friend and used it find for about 2 months
and then outta no where the touch screen stop working but the screen would still display i tried reflashing it and i got nothing still non working touch screen then today i went to open it to type a text message and my screen goes completely white while in keyboard mode
anyone gotta idea whats wrong?

This is quite likely a loose hardware connection. There's a thread here somewhere with a link to the hardware manual. You need to take the unit apart and check all the connectors going to the screen.
The caveat to this is, if you've recently loaded any software, that should be the first suspect. Barring that, though, I'd fall back to the hardware fault.

alright yeah thats what one of my friends was saying
he has a mda also and he was like sounds like wires are coming lose
any ideas on where that thread is?

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

Crazy Tytn screen and button problem, please help

Hi all, this is my first post on this forum but I've been reading for a while to educate myself.
I've got a Herm200 that I've been trying to troubleshoot but to no avail. I'm fairly certain that it has a hardware problem but I haven't been able to isolate anything.
Here's whats happening:
Occasionally the screen will come out of stand-by all white. This will also happen randomly if i touch the screen to perform a command. While the screen is operating, sometimes the buttons on the face will stop working, however the buttons across both sides will continue working just fine.
When the screen turns all white a soft, hard, or stand-by cycle will not always bring it back to life. The fact that the hard reset wont always fix the problem makes me think it's a hardware issue since the phone will boot-up with the the all-white screen.
This is incredibly frustrating especially since HTC wont accept any warranty claims in the USA on the Tytn.
At first I thought this might be a problem with the ribon connection between the screen and the base but i haven't been able to confirm or discount anything at this point. I have yet to find a way to consistently reproduce or rectify the problem so it's very hard to troubleshoot.
I pretty much have to take a second phone with me everywhere right now just incase i need to make a call. Please help! Has anyone ever encountered such a problem?
Thank you in advance!

Hi. This sounds very similar to a problem that I experienced with a HERMES100. I bought the phone off someone on Ebay recently - someone had obviously scrambled the radio on it. I re-flashed it, and it sprang to life. However, after a couple of days, I experienced a problem where occasionally the LCD would stop refreshing, all the pixels faded away leaving only a white screen. Under these circumstances, some of the buttons on the phone stopped working. Turning phone on/off sometimes cured the problem, or it would require the occasional hard reset. This would happen once or twice a day and I suspect thats why someone tried to re-flash the phone.
In the end, out of curiosity I took the entire phone apart, put it all back together again and now there are no more problems!! Totally fixed!
My suspicion is that it was one of the ribbon cable push connectors on the mainboard - possibly not seated properly, or a bit of dirt contaminating the connection. Obviously when I took the phone apart I must have re-seated it.
If you are planning to take your phone apart, please exercise considerable care because some of the parts are very small and easily damaged. I would recommend buying a proper kit to take it apart. I bought mine for about £5 off ebay. Particularly useful are the plastic spoon "wedges" used to gently prise open the case after removing the screens. Don't use a screwdriver - you will scratch the case.
Good luck.
wow... that sounds like exactly what's going on here, I actually even tried to disassemble it lastnight but didnt have the right driver set. thank you for the advice!
I'll look for one of those sets but what would you search for if i needed to find it?
Thanks again, I just got a set off of Ebay. Hopefully it'll be here next week
With any luck it'll be a connection issue.
I have had the exact same problem. Because I got the Tytn through work I made our IT department handle the issue and I am currently waiting for a replacement and to find out what happened.
Yep, it looks like the problems the OP is having are very similar to the problems we've been having over in this thread:
http://forum.xda-developers.com/showthread.php?t=291027
I'm beginning to think it's a hardware problem as well but not entirely sure.
People in the above thread mentioned that using the scroll wheel a while then moving back to use the D pad fixed the problem (very briefly in my case.) Once I use the center D pad button again it locks the hardware buttons under the screen until I make my device sleep and resume.
Somtimes rather than making all the front hardware buttons unresponsive the issue is that once I use the Down Dpad button I can't use the up button. Pressing up will make it go down, as will pressing down (at least that's working ).
Regarding the white screen - this sometimes also occurs. I can force it to white screen by putting a little pressure on the silver panel surrounding the top, right and bottom of the screen (I have an imate jasjam). Randomly when there's no pressure on the rim and I wake it out of standby, it has a white screen that can only be fixed by turning the screen off and on again.
Finally, the LED indicator seems screwy. Sometimes it never flashes. Other times it flashes sporadically (uneven intervals - we're talking maybe a minute between one flash then seconds before another). When I charge it sometimes the LED doesn't come on but nevertheless it charges. Sometimes if the LED is on it never turns green to indicate a full charge. Yet other times it comes on orange, turns green, then never switches off!
Is it possible that
a) The hardware button problems.
b) The white screen problem.
c) The LED problem.
are all related to some kind of connection going loose? Why would the hardware button problem be temporarily fixable with use of the scroll wheel if this were the case?
The other thread has fallen silent. I'm hoping that some of the gurus in here can offer some input here, even if they don't know the answer but can formulate an opinion. I know very little about these devices.
Thanks in advance guys!
PS - don't really know if I should start another thread, I've posted here as it seems like very much the same issue.
Anybody any idea? advice?
I had a similar problem with my HERM100. I didn't mess around with it too much, I just had Cingular replace it out of warranty exchange (thank god those original ROMs are on the wiki ). I did notice however that after doing a master reset, the screen would function again although I haven't messed around with it too much. I got so frustrated with removing the battery for 5 minutes and STILL powering on with a white screen that I just threw it in my back seat until the new one arrived.
I don't have these screen issues. I only have hardware button problems. It's so damn frustrating! I already own a replacement.
I just received a call from my girlfriend. I wasn't able to answer the phone with the buttons, only with a screentap. I also wasn't able to close the call with the hardware button. Since the side buttons work, I went to settings -> phone, closed it, and there we go. The hardware buttons worked again.
Why the heck is this? I truly hope for some wizz out there with some advice, since HTC would only tell me to send it back after replacing it with a new TyTN with same issues.
Regards,
DM.

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 and the following day the call and end buttons remained lit and wouldn't turn off and they also wouldn't work.
I soft reset, nothing, I then removed the battery 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 dabbled 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.
Below are links to 2 kits I'm thinking of getting. Is either one better than the other?

Both kits look ok. PDA one tells you a little more but the basics appear to be in both.
I'm curious though you soft reset and took the battery out, but have you done a HARD reset? I would always try this first before dismantling.
Mike
In my case, they also are always lit up when the screen is also active.
And no matter what ROM version, they occasionally stop responding. Side buttons keep working.

I couldn't do a hard reset because the buttons weren't working.
I have made some progress with the phone now. Found a tech guy who looked at it for me. The white screen is gone, but the buttons still stop working from time to time.
All the connections seem ok.
Is there anything else that could cause the buttons to malfunction?

Nothing obvious.
Have you got applications installed that you have loaded - could be one thats playing up.
Have you now been able to do a hard reset?
If taking device apart and reassembling improved things it does suggest hardware though and might be worth double checking all those multi-connector blocks for good connections - i.e. take them out and in a few times to ensure any oxidation on contacts is removed.

If it wouldn't be a software issue, why is it, in my case, instantly resolved when going to settings -> phone with the side buttons?
i had this problem i took it to a guy who fixed the problem he said it was a very small tear in the flex cable which causes this white screen every now ant then and the buton problem , sorry to say its the cable problem and u need a very capable person to fix it or replace it with a new one . its very common problem baised on the guy who fixed it .

Exactly what is happening to me, no white screen issues, just screen taps and answering calls, I also have another problem where the PDA will not allow me to open anything, be it the start menu or contacts, it will open and quickly close again. I have had mine swapped through Telstra in Sydney, it worked fine for a while and then the same crap again. These problems started before I even touched the OS, so it must be a build problem. Maybe we should write a joint letter to HTC letting them know that there is a serious problem with their machine.
I have had the same problem, got my Tytn through work so we sent it back to the company that supplied it to us. Got it back yesterday and they had replaced the "switchboard". Not sure what it is but there was the problem. Had white screen and buttons not working.

Problamatic LCD screen on my Wing looking for help.

OK I have had my T-mobile Wing aka HTC Herald since last April.
Just a few days ago I encountered a problem with my lcd. And I would like your guys feedback if possible before I purchase an lcd replacement.
My problem is when I slide open the wing my screen starts to fade, (almost making it look like a negative from a picture) after that it starts to fade to different colors.
Now the problem persists when the phone is closed, however if I tap the top of my wing and hold it the screen becomes normal, but once I let go it starts to fade again.
I would like to know if any of you experienced this with ur phone and if a replacement lcd screen will fix the problem or am I sol?
If it helps im running my wing on Open Touch v6.0 WM 6.1 Build 20273.1.3.3
Thanks in advance.
LCD problems
Hello,
I too have some weird LCD problems and instead of creating a new thread I thought of posting in this one.
For the past few months, whenever I get a call or resume my phone from standby mode using the power button the entire screen goes white or sometimes it has green or blue colored lines all over them. I have to keep on pressing the power button few times to get proper display. Also whenever I open the qwerty keyboard the display goes blank. Since I am out of warranty Tmobile is not ready to replace the phone and I contacted the HTC customer service and they told that the display unit and some hardware stuff is gone and it needs to be replaced and will cost a minimum of 170$ and will increase if they had to replace some other hardware.
Please note that, my screen is NOT broken and the touch screen too works fine. Recently the display has gone completely blank or too faded even to see whats there in the screen I could barely see the today screen.
I searched and I did not find any similar issues that other folks have faced. Since the LCD and the touch screen is not broken replacing them is not going to fix the issue, correct? I was using open touch and recently I updated the latest official Tmobile release of ROM 6.26.xxx. I also tried the hard resets too.
Any other ideas/suggestions will be of great help for me. Thanks in advance.
I am having some similar problems as well, but my problem is much more severe. My screen is completely black and it just happened this past weekend. When i slide the phone the screen used to flicker but now it black as well. Phone works fine but is useless due to the fact the the screen is out. I remember seeing a program where you can interact with your phone via your pc when something was wrong w/ your screen (cracked, broken, etc.) I have searched the forum but to no avail. The program was very simple and effective. I plan on replacing my phone but would like to retrieve some info off the one I have. I just need that program! Anyone please HELP US!

Screen problem when opening (Wing)...

A friend of mine brought me his Wing to look at for him. If I turn on the phone on it boots up and the screen looks just fine. When I slide the screen opened to use the keyboard the screen freezes and when I close it again it gets all jumbled up. There are lines going through it and I can not make out anything. The phone isn't locking up at this point because I can press menu buttons and other hard buttons and see the screen react, I just can't tell what is happening.
I assume that this is a hardware problem. I was thinking that the cable that connects the screen may have been jarred loose or damaged in some way. If that is the case do you think that it would be as easy as opening it up and repositioning the cable? I don't have any experience with this phone specifically so I don't know if this is a common issue.
I was also wondering if it is possible that this is just a software issue. Maybe the function that rotates the screen for use with the keyboard is messing up and jumbling the horizontal and veritcal lines when going back and forth. I was thinking about doing a hard reset and seeing if this clears up anything. Any thoughts?
I appreciate any help. This forum has always been there when I needed help in the past. I'm sure somebody out there has much more experience and knowledge that I have and can lead me in the right direction.
Thanks for any and all help!!
Update...
So I went ahead and tried the hard reset first hoping that it might be a software issue. I am now at the screen that says "Tap screen to setup your Windows Mobile based device." No screen touches are being recognized. This seems to support my thoughts that there is a loose cable or bad connection. Agree?
I just slid the screen opened to see what would happen and it faded to white.
Yep, if my experience with the Wizard tells me anything, the flex cable from the main body of the phone to the screen is either loose or damaged somehow. Even a small nick or cut into the flex cable will cause it to stop working correctly. I would hunt up the Herald service manual and take your device apart and see what you can find.
Thanks ... I downloaded the service manual and plan on taking it apart. I have to make a run to the store though and buy a small enough Tork screw driver. T5 or T6 I believe.
Thanks again, I will post with my findings when I get going on it.
now what?
So ... I have the phone completely torn apart. I do not see any loose or damaged cables. It was dirty inside the phone but other than that everything looks just fine.
Does anybody have any advice as for things to look for, that might be causing this problem, while I have this thing torn apart?

odd backlight issue

I have a odd backlight issue going on with my G1 i took some pic and now the backlight won't come on no matter what setting I choose, if i slide open the screen and tap the backlight setting it comes on but it won't with the screen closed any thoughts? oh and when i open the screen I have to change the backlight setting in order for it come on
Question and hopefully someone has an idea could this be hardware and here is why I ask if I turn off the phone the backlight doesn't comeon at boot if i open the screen and boot the phone it does.
I am stuck and hate to set and dismantle the phone for no reason
did you drop it? a lot? lol not sure why that would happen unless the rom has a bug in it... what rom are you flashing? or is it stock tmobile firmware?
to be honest I don't remeber which rom I flashed it about a yr ago it has been working fine since I decided to dismantle the phone to check the ribbon cables as I noticed if i open the screen just a bit the screen works. however they were fine does anyone know how the screen switch on the G1 works i was thinking maybe it may be the problem as while i had it open I put power to it and played with the ribbon cable and it had no effect but moving the screen did.
Thanks,
yonu
P.S. sorry for long post
hmm. maybe a wire or sensor got unplugged or moved when you dismantled it... with out seeing it i cant really think of what could be the issue... i kno you tube has 100's of videos on taking apart the g1 lol maybe see if you skipped a step...?
Nope didn't skip a step I simply was hoping tat someone knew how the screen switch worked so I could try bypassing it as I think it is my problem
