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??

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

[Q] Urgent help needed please

i am a newbie to this site. I am using htc hd2 and it worked good until yesterday. suddenly today the touch screen is not responding but all the other buttons working good. i made a soft reset,hard reset but no use still touch not responding. Can anybody please give the solution for this. I am having some important information in the mobile and i hided with file hider software. now i am unable to open it. somebody respond please.

The digitizer is most likely dead. It's caused by the power/end button on the HD2. You can try push the call and end button at the same time while at the lock screen and see if it will give you any functionality. Seen that helped for somebody on here before. Only other ways are to take the phone apart or to replace the digitizer.

you press both call AND end call buttons at the same time

If you get some touch functionality back you may find using MyMobiler (link in Sig) helpful in operating your device & recovering/backing up important files.
MyMobiler allows you to navigate the device via PC/notebook mouse/touchpad & keyboard thus overcoming the problem of dead touch panel.

Yes no touch response is s common for faulty digitizers. Yes you can do it yourself ic you want, but be warned the HD2 is said to be a somewhat difficult to take apart and put back together unless you are just very apt at doing such things. You also need to know that you can get a digitizer and LCD combo for a somewhst dicent price. If you have the T-Mobile 1024 HD2 you will not have to solder your new digitizer to the mainboard. If you have the EU or any other HD2 you will have to solder the new digitizer to the mainboard.This might help you make your decision.

how much it costs to repair approx

$200 I think is the average, if you have the T-Mobile version & can handle dismantling electronics it is quite simple to do yourself but care, some luck & research is required.

[Q] [HELP] Hardware Buttons Pressing Eachother

I just got an HD2 so I could run mango.
Only one problem though.
The hardware buttons are pressing each other.
For example,most of the time when i press the back button ,it presses the power button instead. It's like the spring or whatever is pressing down both if them and hutting the power button first. It also happens a lot when I press the Windows button,which will press down the back button instead. It's definitely a hardware issue. Has anyone else had this issue? Does anyone have a possible fix?
Thank you!

Somehow, the flex assembly for the buttons became misaligned. You will have to take apart your hd2 to fix it..

Has anyone else had this problem and successfully fixed it?

I watched the disassembly video when I replaced the housing of my HD2, and you have to take it apart pretty much completley to reach the buttons.
The risk of damaging something is pretty high, isn't it?

You got your HD2 used? I would guess it's a sign of wear.
I'm experiencing the same problem, not most of the time, but sometimes.
Since I'm on Android I started using Button Savior some time ago, hopping I can preserve my buttons a little longer. Don't know if there's a similar app for WP7.
...but sooner or later it'll be time for a new device.

Yeah, you will have to buy new tape or use CA glue to seat the lcd/digitizer assembly back onto the chassis when you put it back together. The risk of damaging isn't that high if you be careful to not touch the button contacts (they will fall off but it can be fixed with tiny drops of super glue) and careful not to rip any flex cables.

[Q] HD2 Disassembly Errors

Hi,
I just recently disassembled my HTC HD2 to replace the digitizer + lens and now it works, but I believe I may have scratched the LCD during process because now there are scratches/blurring on the top right portion of the screen (as seen in this pic imgur.com/vYjbn)
I just want confirmation that it definitely is the LCD that's causing the issue as I'm about to order one to fix my mistake, or if it's some other component that I overlooked.
Also, the up volume button doesn't work but the down one does. I've tried probing it with tools (since I lost the yellow/black bumper thing), but it's unresponsive no matter what. Anything I can do about that?
Thanks in advance!

cracked LCD, new LCD needed ...
Yellow black popper cap is needed as that is the button ...

The bottom one works without a button however, when I probed it with a flathead. For some reason the top one doesn't work. I don't think not having the button is the sole reason, perhaps a link was broken or shorted.

Black part in cap is the contact pad to bridge the points on the button board, without the cap the button has no feel & no function. Never seen volume work when missing & I come across a few that have been missing or temporary missing during assembly.

[Q] Strange screen Problem HD2

Hi guys, first post. So heres the problem. My HD2 screen is not glued properly to the base of the phone and it has a little space between them at the bottom right corner ( next to the Power button), whenever i press the screen to close the gap the phone freezes, and i have to remove the batery. It is getting really annoying couse i cant even put the damn thing in my pocket without it freezing. The hardware keys dont even work i just have to restart it. So my question is does any1 know of this problem and can he/she offer a way out?
Sorry for my english. thanks in advance

Sounds like it been opened before & had not the best assembly.
Would imagine hardware button ribbon is torn or pulled out of socket hence no buttons.
freezing issue could be down to issue with digitizer ribbon or button ribbon or worse ?
Do you have any issues with screen touch & do you know full history of the handset.
If black Void sticker is missing from case screw near battery pins then you know it been opened & most repairs including so called specialists are poor from ones I've seen.

I know this is the last thing you want to hear but if it were my device I'd take it apart and redo the assembly myself. Theres plenty of how-to videos with detailed steps. Hope this helps.
