No response from screen after pressing the back key... - HD2 General

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.

weird hardware keys

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
Chabun
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.

[Q] Is there any way to flash the rom without volume buttons

Hi Friends,
My HD2 digitizer was broken when I got it and I decided to replace the digitizer by self. Everything went well, and when I assembled the phone back I noticed that I have damaged the side volume buttons they dont click at all.
so My question is there any other way to flash roms. I currently have a android Sense 3.0 rom loaded on to it. Please advise....
No you can't that
you could just search the forums. there were some threads about broken volume buttons and as far as i can remember solutions were found for your problem.
Any thread links???? please....
boot into recovery and the HOME & WINDOWS BUTTON act as a volume up or down,so u can select what u need using these buttons
Just the same way i had damaged the front hardware keys ribbon...so none of the front five keys work....any soluion for that??

hd2 touchscreen problem

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

[Q] touchscreen stops working after pressing power button

since yesterday, i have this nasty problem with my touchscreen. when i press the power button to wake the phone, or to get into the power-menu, the touchscreen stops working. this does no happen if i press any other button.
sometimes, i can use the phone again if i wait until the screen turns off and then wake it up by pressing any other button, but most of the time i need to pull out the battery and restart the phone. even when i pull out the battery, the screen won't work sometimes, and i have to restart the phone again.
when i first experienced this problem, i was using the nexushd2 v2.0 rom, i then updated to the v2.1, which didn't help. i tried reinstalling the rom, wiping the /data/ , the cache and the dalvik cache (multiple times) and eventually changed to the typhoon cm7 rom (with repartitioning and reinstalling the magldr), the problem is still there.
the phone did never get wet, fall down, or anything the like. pulling out the sd card makes no difference.
i hope someone can help me there
May be it´s a hardware problem, some HD2 have it.
You can test it, if you go back to windows.
its the good old digitizer its right under the power button press the end button hard and it should work again but if you press it again it will corrupt use softkey or remap your hardware buttons

Lol, I was about to do that
@OP, in future please use the search button before posting. There are far too many threads in this forum with exactly the same issue as Kamerius has just proved, so why couldn't you save both us and yourself some time and search first? Anyway, what you have is a digitizer issue, but a quick temporary solution is to simply press as hard as you physically can on the end call/power button. The screen should work after that. Use a button remapper or some sort of widget to enable you to use the phone without ever touching the end call button, and make sure to use other buttons to wake the screen.

i have the same problem with the endkey but with the rom in my sig
it actually has a softkey button that can be setup with a power softkey ..longpress on the softkey and it pulls up the power menu
just like it would do if you used the hardware power button
Yeah I thought there were softkey power buttons but I wasn't sure and I'm on my phone so couldn't be arsed to search

well, sorry dunno why i didn't search the forum before
pressing the power button hard worked , but i think i'll keep using soft buttons and wake the device pressing any other button (i don't think the brute force method is a good idea as i want to keep my phone some time longer )

[HELP] Screen works bad with any android ROM

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.
