Different screen going to white problem.... - 8525, TyTN, MDA Vario II, JasJam General

Alright, this problem is a bit different than what I have seen. The screen goes to white when the phone is closed, meaning the keyboard is not slid out. I tried the put a plastic piece under the D-pad trick, still a no go. Now whats weird is if you slide the keyboard open, everything works perfectly fine, the screen acts normal, but as soon as I slid the keyboard closed, the screen fades to white. If I slide it open again, it works normally without even having to do a hard reset. This time it seems to be the LCD since I tried it in another phone, and the same problem happened, so is does anyone know what part of the LCD would need to be fixed? Is the solder on the ribbon going from the digitizer to the LCD loose or is it something that I can't fix at all?

OK another thing I've found out is that it only happens with the AT&T WM6, when I have WM5 on the phone, the problem does not occur at all. If I turn the phone on in bootloader mode, the problem is not there at all either....anyone have any idea what it could be?

Tried LCD
LCD is not the issue I have replaced it. Still have white screen...
I'm thinking it might be the flex cable..

This isn't inconsistent with some of the other things I have read on this issue at all. You're saying you haven't read about it occurring in conjunction with sliding the keyboard in/out but others have definitely noted that this causes it to happen for them.
So I would look at fixing it the same way -- troubleshooting the d-pad cable. If you have already tried this, then double-check that what you changed hasn't fallen apart and also make sure you did exactly what others have said to try.

Any hardware experts here??

Hi,
I am still trying to resolve an on going screen problem.:-((
When I have my Universal opened up on my desk the volume and phone dialogs and occasionally the anolog/digital clock dialog keep on appearing and disappearing.
Some times it hardly happens at all and other times it is contant, to the point that the touchscreen won't respond to other input.
When in PDA mode I get a similar situation from the same edge of the screen, but this time the scroll bars go mad.
Previous posts here have suggested either grit in the edge of the screen or dirty contacts. I have pulled the screen apart and cleaned all the contacts as well as cleaned the edge of the screen and the case around the 'affected' area.
Since the problem seems to be down to one particular area of the screen - is it more likely to be pressure from the case or a connection issue.
I'm inclined to think it is pressure from the case, but don't know much about how the touch screen matrix works.
Any help with this would be appreciated - at the moment the screen problems are rending the device pretty unusable.
Surely someone here mush have some ideas, this is driving me mad.
Currently running with the back of the screen off and prodding and pocking at connections to see if it makes any difference, but doesn't seem to.
Next stop is to strip down the base to see if there are any issues with the connection of the screen cable on the main board.
The frustrating thing is that the problem seem to appear and disappear - sometimes it if fine and then other times the dialogs are appearing.
When I have the dialogs appearing I try opening and flipping the phone back and forth and sometimes it goes back to normal but more often than not it doesn't.
The first thing that I want to establish is what is likely to be causing the icon area screen to appear as though it is being pressed?
Cheers,
Julian
I'm definitely no hardware expert but my Universal showed a similar behaviour a few days ago and I'm quite sure it has something to do with the case and/or the cable(s) between the screen part and the main body of the device.
In my case, only a small part of the touchscreen (lower left corner) remains working and the speaker on the display side also refused to work anymore. I've applied some pressure on the edges of the display and the speaker "slowly" began to work again... and so the touchscreen did.
Good luck :?

Is your phone now working properly?
I have had the screen apart, but do major change. Next stop strip the whole thing down.
I'm starting to suspect the cable, but cannot see any obvious problem with it.
Yes, currently my phone works perfectly.
Did you check the connectors "inside" the display part of the phone (e.g. receiver, ...)?
.ox
Hi,
I have opened up the back of the screen and checked the connections of the ribon cable to either side of the screen and also checked the connection of the actual screen to the circuit board.
It would be useful to know a bit more about how the touch screen side of things work bearing in mind that only one corner of the touch screen is being affected.
I'm going to try to strip down the whole phone and check the connections on both ends of the cable between the screen and the main unit to see if that makes any difference.
Well, I have stripped down the phone and cleaned the connections on both ends of the cable between the screen and the main board and at first for a day or so the problem appeared to have gone away, but now it is back.
I am starting to suspect that it is a problem with the actual cable, possibly a loose connection in the wires - the connectors appear OK and problem appears and disappears when the screen is flipped.
I read here that you cannot buy the cables seperately - is this true?
The next option is to take the cable out and either check all the connections and repair it, however it is a random fault so difficult the trace.
The other option I have considered is to bind the cable tightly with PTFE pumbers tape which is thin enough not to cause any problems, the PTFE will bit will help when flipping the screen and binding it might (hopefully) ensure any loose connections don't remain loose.
Any other ideas from here?

Wing sliding keyboard problem

hey i was just wondering if someone could help me out here, ive searched around with no luck. I replaced my wing's housing because my old one was all scratched everything works fine but i have one problem when i slide out the keyboard the screen doesnt go to landscape mode and i have no idea whats broke checked all the cables and stuff and its all pluged in, the keyboard works just wont rotate the screen thanks
You can try a hard reset, which should cure any software problems.... but if you were messing with the phone and taking it apart in order to replace the housing ... it sounds like a hardware issue.
its defenitely hardware related just not sure what it could be not sure where the thing that operates the screen and turns it when the slide is open would even be
I had the same problem. Their is a little round magnet in the front housing that you forgot to swap from the old case. Its hard to notice but its in one of the corners in the screen side housing. its under the OK button, under the circuit board. on the actual sliding plastic housing. you'll see a small round recces thats where the magnet goes.
the wing has a Prossesser Of 200Mhz, so what that means is its pretty slow.. just uninstall unused programs and End programs that your not using. Its also possible that your firmware might not Support Sliding.

Touch Screen Not working.. plz help.

Hi mates yesterday i bought a used herm...with excellent condition. but when i opened any dialog. the window closed automatically. and the screen light remains always on. and touch is creating problems.
and after some time the touch screen totally stop working. i dont know what happened. al the buttons are working fine. i upgraded my t-mobile herm to its original t-mobile wm6 rom. and again the touch screen is not working. and the screen light always stay on..
so is this hardware or software problem.?
guide me if you have any clue about this..
according to my thinking.. i think some button is pressed continuesly.. but everything is working fine.. only the touch is not working.
broken digitizer for the touch screen, buy a replacement lcd/digitizer together and replace yourself, about $100Aud. Use Mike Channons site to download the service manual. Use the search function and type in "htc service manual hermes".
As for the light, you will have to use your buttons to navigate to settings>system>backlight>battery power and external power. you can select how long the backlight remains on for.
Cheers...
Hi mate thanks for your reply.. Actually the situation is that. the screen is working perfectly. all buttons are also working perfectly. but suddenly the touch feature stopped working.
that time i was just opening some menus and they closed automatically. it looks like that there is some button pressed. and the screen light never stops. it continuously remains on. all buttons are working perfectly and everything. on the touch feature is not working.
i upgraded my device with genuine shipped t-mobile wm6 rom and again it stopped at the starting screen where i have to click the screen and the device brings the window for stylus adjustment.
so i wanna ask that is this also possible that some touch drivers are corrupted or something like this.? or is this a hardware failure.?
Kind Regards
I had same problem, it was hardware. Thats why I said to change the lcd. It is theoretically possible to replace JUST the digitizer, BUT, it is a MAJOR hassle.
As for getting past the alignment stage, look up Remote Screen Alignment. Its a cab file that stores the alignment settings on your pc. You WILL have to have a friend that has the same phone so you can get their settings as you need to copy them to your pc first. You can then copy the settings to your phone so you can use it until you replace that pesky lcd...
Cheers.....
I had a similar problem with my hermes. After a lot of investigating, I found out that this is a heat related issue with the hermes. The unit will heat up an some connection somwhere gets messed up and continually registers ghost taps on the upper right corner of the screen, which causes the continual opening and closing of programs/task manager. This overloads the phone which then causes the screen to eventually become unresponsive due to excessive computing.
With my phone, it must be heat related because it will only occur during or after heavy use or overcharging. Other people have had this exact problem with the conclusion being overheating. The worse part is, there is apparently no way to fix this, replacing the screen doesn't change anything. setting your screen alignment very far left will fix the problem but then everything you tap needs to be compensated for.
Good luck, hate to be the harbinger of bad news, but it's better to know whats wrong and that you can't fix it then not know whats wrong and keep trying to fix it.
same problem here... only my hermes is overheating already after 5 minutes use...
in the morning it works and when i put it in front of the airconditioning the touchscreen also works...
somebody who has an idea where to look for a solution??

Click to expand...
Click to collapse
Some of the suggestions in the white screen thread/s might help. The problem is that those who have the heat related problem will find it very difficult to trace the actual fault. The heat may be causing miniscule expansions on the boards / components and connectors. The tiniest of cracks or poor connections can therefore break with the expansion.
Another theory is that rather than heat it might be a capacitor that is breaking down either over time or again through heating. Unless you are a skilled electronic engineer that is virtually impossible to check, particularly since schematics are not available.
You might just be lucky if you dismantled and re-assembled - it might just re-set a connector or adjust a board so it does not get affected in future. That would be very much a matter of luck and of course potentially the situation might be made worse!

Hi mates. I am back with some issue.. i moved my device to a repair center and he said that its a software issue. and he fixed my device without changing any rom.. i dont know how..
but again when i open some window like programs. the right scrollbar make a problem... when i move scrollbar it automatically press the top close button..i aligned my screen 3 times but same problem with right side scroll bar.
and after playing with it. the touch totally stopped.
now the thing is.all the buttons are working fine and everything is working fine. even sms and calls. but when i check sms and press my scroller button. it displays the right click menu instead of opening the sms. and the screen light is continuesly on. as something is pressed. so. i think this thing wil help. i am now trying this method to check my pc.

check this out as well.
i will send you details soon.
might just have something lodged between the case and screen.. also to get rid of the screen alignment, cable it up and delete welcome from the startup programs and then reset it.. should get you past it so at least you can use it until you repair your screen

In-Call: Screen turns off and unresponsive

Hi everyone,
I recently changed my HTC's Aria digitizer because it was cracked.
During the process everything went smoothly however after that I have discovered that when a person calls me or when I call someone the screen turns off and never gets back to normal if there is no other "stimulation" such as putting the phone to charge for example.
My guess was there was a problem with the sensor so under settings I chose to keep the screen awake at all times during a phone call, still, I am having the same problem.
The weird thing is that sometimes when I remove the battery cover everything works fine and the screen keeps on, but sometimes not, so its not a constant rule..
I may have messed up something during the replacement of the digitizer (its just the glass not the lcd) such as removing the sensor and not placing it back correctly but the thing is that I dont really know the components of this device so Im not sure what is what..
If anyone could help me to understand the problem a little bit I would really appreciate it.
Thanks in advanced..
Anyone? Please
The sensor is right above the AT&T logo. If the little rubber ring isn't perfectly aligned with the sensor, you will have this problem. My wife's phone has a similar problem and it is fixed (temporarily) by firmly pressing on that corner. The adhesive strips have failed and I am looking for a source besides "Repairs Universe".
Thanks a lot!
I will try to take apart my Aria again and see if I can align it correctly
thanks again
glad that i found this, having same issues with my wife's aria, will give it a shot

Digitizer suddenly broken?

Yesterday I was working on my HTC HD2, flashed WP7 Mango on it, and opened it again to align the plastic keys with the hardware keys undeneath. It didn’t really work out, so I carefully seperated the digitizer from the display to realign theglass abovethe keys. Now The keys work perfectly, but the screen doesn’t react anymore. I have no clue what could’ve went wrong, the digitzer flex cable is still perfect, aswell are the others which connect the screen to the motherboard. Anyone have a clue what could’ve went wrong? I hope it can get fixed easily
I’ll try to hold the ‘end call key’ while using the display. Seems like that will help to entight the connection.
Fix: So I took the Display out again and checked the connection of the digitizer at the back of the screen. It was loose. So i've put it in place and fixed the connection with some extra tape.
