i am running on HD2O© WP7 8779 (TANGO). For some reasons, the touch screen randomly stop working. Usually it happens when i try unlocking the screen. I am not sure is it hardware problem, or is it software problem. Anyone got any suggestion on how i should approach this problem? Thanks.
If it's a hardware issue, it sounds like the digitizer is dying. That's a typical HD2 problem. The display's wire are underneath the power button. If a hard press on the buttons helps (well, sometimes), it's exactly the described problem. Unfortunately hard pressing damages the wires further. In any way you'd be in for a replacement display or device ...
BTW: Running WP7 you can remap the buttons to avoid using the (original) power button on the right (e.g. with Leo Advanced). If the damage is not too severe it could strech the lifetime of your device.
All by assuming it's a hardware issue (you can find out by running another os) ...

That's unfortunate. It sounds like the same problem I am experiencing. Thanks for the answer.
You're welcome. If the touch still works simply remap the buttons and avoid the button on the right. If it's already too late and you want to repair it by yourself search for tutorials, there are a few available - including videos.

Hey
Recently, I've got strange problems with my hardware keys on my (European) hd2. When I press the home or the back button, they work sometimes like the volume buttons. So the home button decreases the volume and the back increases it.
I'm using Artemis v43 with WinMo 6.5.5, but I had the same experience on all stock rom versions (that's why I got rid of them)!! Even if I m using Android the buttons are still weird. (In Androd it's extremly annoying due to the immensive use of the back button ).
Has anyone else the same experience and how did you solved this? Or should I send it to HTC to repair it?
Thanks for your help

maybe you had a short in your motherboard, i would recommend contacting HTC, as it is a hardware problem
Thanks.
Yeah, it really seems to behardware stuff. I'll contact HTC.
Yes I have a strange problem with my HD2. When I press the back key then screen going dead and there is no response. Display is ok. Everything are running and phone don't freeze but touch function losing. If I press the power/end key to sleep the phone and wake it up again then everything are normal. LCD responding my touches and sliding screens with no problem until I press the back key.
I tried several roms with full wipe (task29) also tried stock wm 6.5 but nothing changed.
If this is a hardware problem why only occurring when i press the back key? Because everything are ok until back key.
If this is a software problem why occurring after full wipe?
I am confused and need help.

Sure it is a hardware problem, well-known for HD2's architecture!
Back & End keys are right above/overhead touchscreen contacts on LCD: after some (many) pushes on those keys, touchscreen fails eventually for good!
You should think to replace your own...
Thanks for your reply. This is bad news for me because my phone doesn't have warranty. There are some touchscreens on ebay but i confused which one is suitable for me or best quality. Some seller says lcd + digitizer or some one says just digitizer. Which one i should buy? Just digitizer or with lcd?
Best regards...

If you DIY I would recommend you the combo(LCD+touchscreen), whatever version( but I suggest you the 300 version with a clip connector between touch and LCD): it is much easier for a rookie to replace whole combo, but take care, it's not that easy!
If you go to service shop, pick a good one(it is a tricky action even for a pro) and replace just touch, they should know what version to be.
Good luck!
it's the hardware problem, the only solution is going to the HTC's service center or buying a new lcd display and replace it by yourself
Can’t believe it. I just got the same problem since yesterday. When I press the back key the screen become unresponsive. The problem appears only after, but on every press of the back key. I really cannot find what cause this.
Is it really the case that I have to fix hardware problem or there is SW solution? Anyone with experience?

too bad it is hardware ... any suggestions for app I can use?
Even if problem is there with the hardware and button, drivers are OK.. So put android sd version and use software like zmooth or button savior for onscreen soft keys.. No more need for thehard buttons
Use miui rom android, you can set volume keys to switch on screen, no need for power on key
I have never used my hard back key in probably a year's time!

+1 on zmooth, been using like a year too and almost non use of hardware buttons
You need to open the phone and check the mini-flat of the hardware buttons, it is connected to a connector tries to lift the safety catch and push well helped by a small flat screwdriver.
here is a 'picture.
hello all im having a problem and wish to get some input on what the problem may be
my hd2 has been ****in up to say the least i installed a new miui rom on it after having touchscreen problems and the weird thing is i can get the touch screen to respond after holding the the green call button and the home button for one second making the flashlight turn on then holding the back and end buttons for one second waiting for the screen to turn off then turn back on
my question is does this have something to do with the kernel or power consumption it seems it might be the case but im no expert
what do you think?
Try to press once or twice the endcall (red) button. There is a common problem with the Leo's digitizer and it is located under the endcall button. So press it hard. It used to help me.
I suggest you to install button savior or any app with softkeys to preserve the physical buttons.
Greetz,
Dodi
damn that definitely helped it along
thanks
the problem still exist but at least i can use the phone
alas i think its time to move on
that sucks i really liked my phone
Not responding touch screen
Is the keypad fully connected with the touchscreen? Because my keypad flex cabel is broken, and my digitizer doesn't respond. Do i need to buy a new digitezer or just flex cabel? Can somebody help me? Thanks
i haven't checked the good thing is i have a spare digitizer but its a hassle still ill probably end up trying eventually
Hi,
After a night in a tent my HTC HD2 started to malfunction. When turning on the device I noticed it said ''safe mode'' (Android NAND (sensation rom)). At first I didn't think much of it, because I thought the device had turned of due to a dead battery. However after leaving it for a while to recharge I noticed that after each reboot it would return to safe mode. Then I noticed that the device kept showing that it was in vibration mode --> the volume down button is stuck(not physically though). Also the device kept popping up ''recent activities''... I'm under the impression that this is due to a malfunctioning call button, not a 100% sure though.
After I reflashed it to wm 6.5 the problem still prevails. However I was able to get a more detailed view of the issue:
The windows button lacks every response, the call button does not respond on touch but seems to randomely activate the call function. The home button functions poorly. However the back button, power on button and volume up button function correctly.
The volume down button seems dependent on the other buttons. When pushing one of the buttons below the screen the volume down button is activated and is stuck untill the screen is turned on and off. However the volume up button does not yield such a result. The volume down button still is responsive to touch though, as long as it is not stuck.
Any ideas how to solve this problem, or how to work around it? As a precaution I put the HD2 in a box with a moisture absorber.
Hi. I wish I could give you a better understand that what I can offer but what I think happened is you probably rolled onto your phone while sleeping.
This is not to say your problem could have came from something else but let me explain a little about safe mode.
Safe mode anyone can enter by pressing volume down and holding it while it boots up. It allows the developer a safe mode they can enter similiar to
why your computer has it installed on it. Normally pulling the battery and letting the phone reboot clears this out though. With that being said i think what
has happened is the volume button has stopped working as it should. There are several sites you can go to here on the web to send your phone out
to have it looked at and fixed. All in all it shouldn't be that costly and if your mechanically inclined and (careful) it shouldn't be to hard to do it yourself. I
would make sure you take very good notes/pictures in dismantling your phone because if you put it back together wrong you can make the problem worse.
Ebay, listing found here has the volume button and the tools necessary to open your phone and repair the volume key for around $7 usd.
Please make sure your phone model is supported and you have the know how to do this without making things a bigger issue. I would also
suggest to wait for more info because I could be wrong as well.
Thanks for your time, effort and information.
However I don't think it is a problem caused due to physical damage to the volume button. In addition the phone was in a 'sidepocket' of the tent, making it virtually impossible to roll onto it. Because the call button is malfunctioning as well I can imagine it being motherboard related, addmittedly I am not much of an electrician .
The issue has been partly resolved. Only one problem still exists. When I push the windows button it results in a volume up response. I performed a hard reset but the problem still persists, any ideas what could cause this?
Cheers
The hd2 high level of integration can not fall. Even without the screen broke, other things will break, so the sets of sets of silicone can not throw. Screen indeed not easy to break unless it fell out just in time to have something to knock to the screen.
Hi, with any android rom the screen works very bad when i touch the screen for select anything...
I need touch 2 o 3 times for select
With android 2.3.7 and 4.0...
Can you help me=?
Thanks a lot !
It's most probably a hardware issue. Does this happen in other OSes? Try the digitizer trick which basically means pressing down very hard on the power (end call) button and then waking the phone up with any other hardware key. If possible, you should use a power softkey as well to prevent the digitizer from wearing out.
