HD2 New Weird Screen wont unlock issue - help

this is a new problem for me. I have been using the most recent Dutty ROM together with Mdeejay Android ROM without any problems. All of a sudden, when I try to unlock the screen after STANDBY, it just wont register my touch, as if I am not touching it. It boots up fine, and on the first unlock works fine, but when the screen lock goes on again (after every standby) it just wont unlock. So I am stuck (I use Exchange and our policy forces the lock after standby, so I have to use it - and its worked fine for ages).
If I boot into Android, it works fine, the unlock works fine, yet strangely when I try to shut the power down, THAT screen also doesnt register me touching it.
I have hard reset but even before I load an app or do anything, the problem exists.
I also reflashed a DUTTY ROM. Same problem.
I tried CHT lockscreen - same issue. After Standby, screen doesnt register my touch.
Anyone have any ideas?

Same problem for me.. Restoring a backup image after being forced to hard reset this morning and now suddenly my HD2 won't wake up after sleeping. Pressing my end key only lights up my buttons but I have to pull the battery to reset. I'm thinking it's related to me having CHT installed, yours however might be a different problem.

I had something similar. It was right after I had installed CHT 2.0 and was looking to make the top and bottom bars transparent. I found a cab that claimed it would do this and installed it. Sorry, I don't recall what cab it was and I have deleted it. When I rebooted Sense would hang and if it got into a lock it would only move the slider a little where it would stop. Luckily, I had done a backup that morning right after I installed CHT 2.0 with Sprite so I restored and all was well.
I don't know if this is of help but I figured I'd throw it out there.

it wakes up, but wont register when I try to swype the unlock screen.

Your lucky you get that far lol.. I don't get any waking up. Plus I now uninstalled S2U2 and still no change. Disabled all locks of any kind and still frozen with sleep of death with in 1 min of hitting power to sleep it. I REALLY don't want to to a hard reset and install everything from scatch.. UGH.

weird update...
It has something to do with which key i witch the device on with. If I use the phone key, I can swype the unlock. If I use the power key, it doesnt register.
Another related issue: when i hold the power key to switch off, it wont register me touching power off or reboot etc. so I have to take the battery out to switch off. Its the same in Android.
Anyone know? Hardware issue?

SOMEONE PLEASE HELP!!!!

It's a quite common digitizer problem lately... it seems the HD2's digitizer is failing on some units, possibly because of usage with android? my father's device acted the same way, only it sometimes did register touch and other times, not.
My device doesn't have these problems, yet. But seeing that a lot of people here are experiencing these issues, and with the notion that I use android pretty much all the time since I first booted my device, i'm pretty sure i'll experience it soon as well..
Make no confusion thou, the assumption that android effects the digitizer are purely my own thoughts on this matter, no such thing has been proven and the conclusion that android is effecting our HD2s is based purely on the statistics of touch screen failures in the last few months since android has been made publicly available in a working form.
EDIT:
Those seeking A solution, as far as I know, the only solution is sending your unit to HTC for repairs, you'll get it back with a note that says that they replaced your digitizer or your screen, at least these are the reports I heard from the other folks whom followed this procedure.
Good luck.

HTC HD2 Screen Lock
I have only used Android a few times on this 'phone and it has a standard HTC/O2 ROM installed so it must just be a problem with the top part of the digitiser. With android running the unlock is at the bottom and is unaffected.
Is there any way of testing the digitiser before deciding whether to get a repair sorted,

A friend was complaining to me about something like this since last week. I could not figure it out so I went ahead and installed Android cm7 and still have the same issue.
Until I read this post after searching through the forums all over Screen now unlocks perfectly fine but only using the green Phone icon. If I try to wake the screen with the red Power button, the screen is unresponsive.
Thanks for the info.

Already happened tome its a hardware issue can't be fixed so if you still have warranty on ur phone send it to htc for repairs b because it tends to get worse n worse soon other keys will start to give in I think that's one reason why most android phone been switching to capacitive buttons because hardware causes this sorta issues and send it in for repairs to get it fixed

the same issue with me , is there is any solution for that .

Wakeup the phone using the send button.it will work

[March 16][Q] HD2 Screen Unresponsive Digitizer - What do I do to fix this?

First of all, I have a screen lcd that is not broken. The screen, however, is not responding to my fingers/touch. I think it's the digitizer. The hardware buttons work fine though.
What do I do to fix this?
Do you think the digitizer connecter is loose or has dirt or even broken?
I have a T-Mobile US HD2 and I think I'm still under warranty but not sure.
Fix Attempts:
I have checked Clockwork Recover and selected advanced>key test
and I get key codes when I press the hardware buttons, but no code when
I touch the screen.
I have tried wiping the data/factory reset & wiping the cache partition
& wiping the Dalvik cache, but same problem.
I have tried flashing different android roms, but same problem.
I have magldr 1.13 and clockwork recovery v3.0.0.5.

Thanks for your help.

Seeing as you have the T-Mobile model of the HD2 you could buy you a small hex head screw driver and open up your phone to check the LCD/ digitizer ( Ithink they both have the sameribbon for the connection to the mainboard)ribbon connector as they just plug in on the T-Mobile HD2. This is a desision that is totally up to you though if you want to try this. But if you do still have a warranty I highly suggest you send it in to be repaired or replaced..

I double tao my end key and press again to wake phone from sleep and problem dissappears for a while not permenantly. Hope this helps

its something with the end key. mine is too not responding.

I've had all that problems
For few month my digitizer was not responding from time to time, but after few "power on" / "power off" it was ok.
After some time it stops working / responding permanently
I try everything !
I didn't had warranty any more so I give my hd2 to non-authorized service and they change only digitizer for 220 PLN ( Poland ) what is about 50 E
Now it's working great again.
If You want to change digitizer by yourself - don't try it - its very tricky and You are risking lcd damage. lcd with digitizer can be bought for 90 E - most safe solution for DIY way.

Afro.

People keep saying that the hang up key is the problem, to me is bs!!! (sorry im about to throw my hd2 real far from here) I dont know what is but it ain't the damn key, ive tried a lot of stuff without luck. Im about to buy the LCD/DIGI stuff, but stop with the hang up key stuff its wrong!

The reason why the end key thing works for some people is that the end key is pretty much like right on top of where the connection on the main board for the ribbon that goes to the digitizer and the LCD. So pressing it sometimes causes the degitizer to work again for a little while.

hey it worked for me! after reading a lot of threads, i bumped to this and tried it. But I guess this is just a temporary fix until I get hold of HTC to replace my digitizer or fix the lose connection inside. well I still have my DHD as a primary device. anyway thanks a bunch!

what i do and works allllll the time is if it turn the phone on and theres no response i double click it fast to turnn n turn on again and like nothing it works

Same here
I recently replaced mine because of the unresponsive screen. The problem was very specific though. If i tried to use the red (end-call) key or the back (left facing arrow) key to wake up the phone the screen turned on but i couldnt unlock it. But if i used either of the other three keys to wake it up it was fine. Also if i used the back key at any time during use the touch screen became unresponsive and i had to lock the phone and unlock it again (using one of the left 3 keys) for it to register touch. I dont know if its because, apparently, those two keys are over the digitizer connection or if its just because those keys were more worn out than the others. It seems the former is more likely. Just some specific info about my experience, hope this helps someone.
Also if you have the "screenoff" app and "button savior" app you can get away with using it like this for a while.

Exactly same problem.. Now it seems a lot of HD2's have this problem.

It's obvious now that the repetitive pressing of the buttons is causing digit. to fail... But I don't see why, when I took mine out... everything was fine (no physical damage), I had my friend look it over with a magnifier - he didn't see any cracks on the cables, everything was soldered in place...
btw... does anybody knows what is the purpose of that metal mesh thingy that is glued on the back of the LCD over the flex cable?

[Q] Touchscreen not responding

So for some reason, the last few days the touchscreen on my phone was being super slow, and id have to turn off the screen, then turn it back on multiple times and keep trying to slide it to unlock. I dont know how this started. Ive been using the NexusHD2-Gingerbread V2.9.
Ive tried other ROMs and restored previous backups and nothing is working. The screen is still not responsive. Ive never had this happen before and not sure what else to do. Its just stuck on the lock screen but everything is unresponsive....any ideas???

Unfortunately, your touchscreen digitizer is dying. This is related to the hardkey malfunction. The only thing you can so now is flash back to stock WM Tom and send it back for repair. The phone's touchscreen need to be replaced.
Good luck,

Yeah thats what ive been reading, and right after i started this thread i was reading on another and read that you can fix it if you hold the power button down firmly (apparently the digitzier is right behind it)....that worked for me.
I think too much flashing and changing ROMS using the power button didnt help hehehe

Try using zMooth or Button Savior. This help your hardkey a lot. Since I have zMooth and Button Savior install on my phone, I no longer have to use the hardkey.

{edit}
!!!!! FIND SOLUTION !!!!!
The digitiZer is under the hangup button. press the button bit hard till it nudges the digitiser a little. it worked for me.
(found it from : http://www.htcphones.net/htc-hd2-problems-with-touchscreen/ )
I'm so cool now!!

I have been living on this solution for almost 2 months now.
However I can't take it anymore not because I am lazy!
but because when sometimes you need to make a quick call or grab that
camera instantly I tend to waste a good 5 minutes trying to make that hardpress on the end key work with the digitizer cable.
My question is, would changing the digitizer work? or is it something else?
Ever noticed that T-Mobile HD2 has soldered digitizer connection to the LCD vs. flex-cable socket in standard Leo?

Help! Cannot unlock screen, touch function not working.

Has anyone of you guys encountered the same issue with your HTC HD2? Care to share the fix you did? Would this mean bye-bye to my HD2 already?

If a clean install (task 29) doesn't help, then I guess you have no other option than sending it for reparation.

It seems like there is a limited life span on the touchscreen. Mine died in October, and I had to buy a replacement because nothing I did fixed the problem.

I had the same issue as you, but in my example touchscreen is slowly dying. For example I can't wake up the phone pressing right (red) button. So I learned that using any other button will not cause freeze of screen. I also discovered that if you gently slap your phone on hand, magically screen starts responding. Weird, but it's ‘working’ like this since 5 months so far.

I just encountered this problem with my HD2 as well. It seems that this is a fairly common issue. Apparently the digitizer for the touchscreen is located directly beneath the red power button and has a tendency to lose its connection.
For me, holding the red power button down with some force for about 5 seconds fixed the issue. Is this temporary? Perhaps, but it has worked just fine for a few days now. Try that out.

Can't Unlock the Phone..
I am having the same problem..I can't unlock the phone..No matter what android Rom I installed.I tried to removed the lock screen and the touch stopped working..But when the phone restarts and you put you pin etc,I can use the phone normally..but when it goes black and trying to turn it on again nothing works on the screen..
Though the hard buttom works..Home screen etc..but can't get the touch to work after the screen goes black!

It's not rom related
I have installed WM6.5 (Stock), Android GB, Android ICS, Android JB But the problem appears to be the same in all
when I press Red button touch doesn't work any more
I would go with digitizer theory
BUT my question is this:
is it gonna get worse? cause for now as long as i avoid Red button everything is OK :good:
and I love my HD2 but if getting worse is possible I have to get rid of it :crying:

Well i had the same problem.now my phone has been to the service centre for reparing

Funny (or sad) thing is we don't have an official service center here
so only option is to replace it or sell it as the way it is

Try this:
Lock the screen normally, screen turns off. (Power button)
To turn it on again by pressing any other screen buttons other than the power button. (DONT USE THE POWER BUTTON TO DO THIS)
I found that if I do it this way, the screen runs normal.

Your device is most likely facing the infamous end button/digitizer dilemma. Since you said it happens after waking up the device from standby (using the power button, right?). As far as I know there is no fix other than a replacement. I don't really remember which part required replacement (digitiser or buttons strip), but I'm sure the only permanent fix was a replacement (until the replacement fails, lol).

If it is just the power button, you could use another button to wake up the phone using button remapper or similar app.
Also, use softkeys for back button, since the digitiser cable runs below these two buttons.

New digitizer is way forward & they like $10USD these days
Like mentioned above you may get some use if avoid pressing buttons but if intend on keeping device for a while repair is worth while.
