Dead Touchscreen

Good afternoon,
Just wondering if anyone could give me a hand here. I have the Hermes in the guise of a MDA Vario II. On Thursday, I was using a Wi-Fi connection and the handset got really hot and since then the touch screen has been unresponsive. Since then I've noticed that one of the soft-keys looked as though they were stuck on (changed colour as though they were in being pressed), so I clicked the hard key underneath it which stopped the soft key from being as though it were pressed but that didn't fix the matter of the dead touchscreen.
I've also tried cooling the handset down and then trying to use it, but that doesn't fix the matter.
I've tried reflashing the ROM (Black 3.0.1) on the device, but I get stuck at the calibrating the touchscreen step as the touchscreen doesn't work. I can bypass the first tap screen command though, by pressing the power button to put the device into sleep mode and then pressing the power button again to get it out of sleep mode. This also happened when I flashed Black 2.5. The weird thing is that my phone will still ring even when stuck at the calibrating screen step but it won't show the caller; it just makes the ringing noise.
I've got to admit that I'm running out options fast. I don't want to open the device up unless it's unavoidable. I've alread had a look over some of the other issues with touchscreens but I can't find a resolution.

I think you are snookered here. Warranty fix may be problematic with all that flashing. You could open up (warranty voiding) to see if a connector has worked loose, but that is very much pot luck. Repair job at full cost - possibly very costly!! (and not guaranteed to be working when you get it back - often they replace the LCD screen that may in fact not be broken!)
Won't go into details of the screen issue - you'll have read them all anyway.

Thanks Mike,
I've got it back to the T-Mobile Hungary ROM now (but it still won't get past the screen calibration). I've been talking to T-Mobile to a seperate issue with the handset and they've said that they'll exchange it, so it looks like I could be sorted. My main concern is that they might query why it's got a Hungarian ROM on it; although I'm hoping that they'll see the splash screens and get stuck at the screen calibration so it won't be an issue.

HTC HD power off problems

Hello,
I have a problem with my HTC HD. From time to time it shuts down without any reason. When I press the power button I can see the Windows Mobile starting...
Did any body else had this problem?
Is there a solution for this?
Thank you

perhaps your battery is not positioned properly or sitting a bit loose? Try a post-it (or something else thin) on the back of the battery cover..

Mine shuts down and won't turn back on without a reset every time I'm in an area with no signal, it basically stays off while I'm at work.

if you keep getting these kinds of nondescript errors and it survives a hardboot, basically there are three options left:
1) try to flash a different firmware or
2) take it back to the store (flash back first)
3) hope like hlll some guru here gets an eyefull of your problem and knows a quickfix (slim chance seeing the number of daily new posts here and the typical guru tendency towards development as opposed to a supportdesk)
I'd set my hopes on 1) or 2). Good luck however you choose.
Cheers,
Rick

Guys,
I'm having quite the same problem: the touch HD keeps turning on and off automatically, as if the power button is pressed (but its not).
Moreover, the power button just don't work. I press it and nothing happened.
I have master reseted the phone and also have changed its ROM, but the problem stills.
Unfortunatelly I'm start thinking that its a hardware problem.
I guess that a solution shoul be reassing the power button, disabling it. Is there any app through which I can reassing the power button?

Have you solved the problem? I have a similar prob, my power button doesn't seem to work when i press it, and if i soft reset (through HD Tweak) when it boots I get a warning message saying " Warning your device will power off and you'll lose your data, Yes No".
It's like the button is half pressed all the time.
Couldn't find any info on hard key remapping either.

I used to have a similar problem but it was with the screen....
The screen used to turn off suddenly without a reason but the phone is turned on and I keep receiving calls. After returing back to my Supplier in Egypt they replaced it with a new one after testing it for three days.
I'm using the new one sine 20th of December 2008 and nothing happened again

Well if you guys are in the US (or have HSDPA/UMTS disabled) then re-enable them (that should hopefully get rid of the restarts in low-to-no-signal areas).
Hope it helps

It's a known issue. Sometimes a long press of the end-call button will bring up the display, but that's rare. It normally needs a soft-reset/battery out to reboot the phone.
It's obviously a software issue as the buttons light up when you press them, then turn off when they time-out, and then light up when pressed again, so the OS is still running happily in the background.

during my search and tries for applications and tweaks for the device, i remember i saw something that assign a display wake up on the long end press, and something that wake up on shaking the device, is there any confirmation if these tools solve this issue?

Nope - try them. You could be the hero that confirms it

Today was my turn to have that issue. Unfortunately :-(
I 've been looking for an answer, but there is no solution. Just a thread that talk about that the issue is caused by SD-card, corrupt files, formatting issue...
Please, do we have any solution for that issue? it started this morning and I have it 4 times today.

hmm. happened to me today. don't know what caused it.

I had this problem today as well for the first time. I thought it was to do with having the animated weather wallpaper and having rain. Today for the first time I had it predicting rain and my Leo kept saying "Loading touch sense" when coming out of lock. It's never done that before.
Then after an hour of lock it refused to wake, despite the physical keys lighting up.

I had this problem also today as well for the first time! But twice, so basically the first time and second time
First time phone wouldn't go on, touching the screen, hitting the spot where the lockslider was (in the dark), pressing short or pressing long on hard-buttons. The phone didn't respond at all.
Second time the hard-keys would light up, but phone refused to wake.

I had this problem.
Solution: Download an app called MemMaid and use the settings in post #75:
forum.xda-developers.com/showthread.php?t=596484&highlight=settings&page=8

For me it was the Disable Auto Device Lock.cab (in combination with windows exchange server) that caused the frequent HD2-doesn't-wake-up problem.
I uninstalled it and it is working fine again.
Have a look here, the exact same problem was discussed :
http://forum.xda-developers.com/showthread.php?p=5386344#post5386344

Aaargh. Just happened to me again. So that's twice today.Locked it with Opera open. Went to toilet. Came back and Leo wouldn't come back. Again the physical keys were lighting, but the screen stayed dark.
I'm running standard ROM that came with phone, 1.48.405.2 and then official hot fixes on top. Only using apps that came with the phone too.
Not done any tweaking besides cosmetic through the standard phone options.

guys let's try to focus here, we all have/had this issue. So let's try to remember what's the last things we dis so we can find the common cause so we can identify it.
Well I said in my post above, I read (don't remember where! ) that the problem is related to the microSD card.
Was logical for me, because I kept copying, deleting, copying tow large files large files in parallel, I mean I stressed my microSD. By the way it's the one provided by HD2 with the copilot in it.
What I've done, is that removed the microSD for a while and there were no freeing again for like 4 hours, and it was with screen off for like 1 hour and half, come back from the fitness, and it's ok.
Once back home, I backed up all my MicroSD to my computer, then formatted it with HD2. After that I copied back all my data to my micrSD. So far so good.
hint: what's the official SD Card Storage Cards hotfix from HTC for?

Strangest touch screen loss problem! + SOD / QUICK WAKE UP TEST WITH YES/SEND KEY.

17/9/2010 EDIT: With a lot of feedback from this thread and other threads, it has come out that, waking up the phone with the YES/CALL/SEND green button is BETTER than waking up with the NO/END/POWER red button for SOD reasons.
----
Hello guys,
You probably know I am actively in the Android HD2 porting community.
I am having the strangest touch screen problem. I am really experienced into winmo and android stuff. Please read carefully.There is a surprise at the end.
BOTH under Android AND Winmo my touchscreen works just fine after bootup.
It first started like this:
At first my touchscreen stopped responding when I hold no button to make a reboot/power off. I thought it was from the usual Android touch screen freeze related to g sensor. Then I realized that it was the same in Winmo! Holding no button ALSO caused touch screen to die even under winmo.
Then it started loosing touch after sleeping. My touch is ALWAYS working when I boot winmo OR android and works for hours if not put to sleep. But it stops working after putting it to sleep.
Frustrated,
I restored with spb backup. Didn't work.
I reflashed my winmo rom. Didn't work.
I made a hard reset. Didn't work.
I removed sd card. Didn't work.
I removed sim card. Didn't work.
I changed the date. Didn't work. (this was a strange fix for some blackberries)
I flashed original 1.66 Turkish rom, 2.07 original old radio, even original 1.42 SPL which makes this hd2 fully stock the day I bought it. Even made another hard reset. Still didn't work!
By this time it's obvious this is a hardware problem and needs warranty.
OK
THEN I FOUND THE STRANGEST THING:
If I wake up the phone with ANY hard button other than the NO/HANGUP button touch screen WORKS!!! (Yes/Send button under Android)
BELIEVE ME, I HAVE TRIED FLASHING REFLASHING RESETTING AND TESTED 100 TIMES and YES it is ALWAYS the same. This is not a random thing.
If I wake up my phone with No button under ANDROID OR WINMO, my touch doesn't work. But if I wake up with back button windows button home button yes button, the phone wakes up properly AND touch works. Android of course doesn't work with the original radio, so I wasn't launching Android with the last test.
HOW IS THIS POSSIBLE AT ALL?? It looks like hardware fault, but touch loss IS related to NO button!
I will send my phone to warranty anyway but it will happen after the holiday (not before mid september)
IF ANYONE have an issue like this, PLEASE post.
I just want to make sure this issue isn't related to Android porting. If it is, this might be an important info. Maybe it may help devs fixing the general touch screen and wake up problems. Also everybody TRY waking up Android with the yes/send button to see if it helps with your wake up or sod issues and provide feedback. Also it may help with the phone not responding after hangup in Android. There is something hardware going at the background with the no/hangup button. I know this issue is hardware fault but still may shed light to our problems with touch screen and wake up issues. Maybe there is something hardware or firmware inside the phone waking up the digitizer. I know that hangup/no/end button is internally different than the other buttons, something like it shares the power button function that is usually on the top of the device with other htc devices. (Mine is a european hd2 and the hangup button is not red) I also wasn't using an overclocking kernel.
Please think twice before posting, and don't post anything useless. I am absolutely no noob, you can search my previous 200+ posts. I wouldn't post anything unless I am definitely sure. And I have a feeling that this thread has the potential to help or make something come out. If it doesn't, no harm done.

since most of the time inwinmo or android the no or yes button pop up generally on the same side in both os's and , taking in consideraton it might be a hardware issue , i would say you issue might be a harsware issue undr the screen when you touch no...wild guess

I was the same problem.... but it is even worst for me now...
Before, at least work touch others buttons... now my touchscreen DON'T WORK. :-(
I suppose that it's a hardware problem :-(

BIt strange this one to be honest I think it may just be your device as there are now hundreds of users of android on the hd2 and this is extremely rare. Hopefully a dev will look into and find a possible solution but I doubt it. If I was you I would put it back to stock and send it off to HTC for a new one. Even if a dev manages to find the problem you will have a new or as new hd2

I have been trying and I must say that I sort of do share your experience. The most left button (referred to as yes) awakes the phone just right as where the most left (No) takes its time to start the phone. I haven't had any noticable touch issues that could be related to these hard buttons yet.. (I think)
But I do think you have a point.

Interesting, I had something similar. I was using elegancia rom v1 for the longest time, with all my android builds, no problems. Then I went to chunkydroid rom, and had a few issues, with multiple android installs (one of which was my original that was working before.)
Then I rebooted into chunkydroid, (windows), and had the same issue. It was strange. I tried a few other roms, same problem. Turned off the phone, next day, reflashed chunky again, and hyperdroid 1.1, no issues since. (Only difference, which I don't know if it's related, but again, might help, is that I was overclocking. I have since not let anything go above 998 in setcpu, and even removed all builds that were overclocking. I though it might have had something to do with it (and the phone wasn't warm at all.)
I have not been able to duplicate the problem since though (even with overclocking just to see). So I'm pretty stumped. I'm sure the devs will work it out.

I have taken to pressing the yes/send key to wake up my phone as it seems more consistent than pressing the end key. My theory is that multiple wake up/sleep messages are being sent on the end key and the system gets confused. Some sort of debounce might help.
Just my thoughts.
Running shui8 realstock rmnet with micyprima r9.

It seems waking up the phone with the Yes/Send button somehow seems better with current builds and kernels.
I am asking everybody reading this thread to try waking up their Android devices with the yes/send key and share their experience if it is making their Android wake up quicker with less SODs.
Note: I am still using yes key wake up as a workaround for my hardware touchscreen fault. Still absolutely works everytime. I found out that if I accidentally try to wake up with the no/hangup key I need to wait about 10-15 seconds before yes/send key does its magic again.

well, i tried there is absolutely no difference between any hard button. if i have sod, none of them solves... actually its not sod i think, when you try to put standby and wake up several times quickly, screen stops responding for a while. you need to wait at least 15 seconds between each standby and wake up. can i fix this? or this is the sod?

Waking up with the yes/send button would not make any difference if your phone can wake up good with the no/hangup button already. But we are trying to find out if yes/send button wakes up better in long term usage. (no/hangup button sometimes can't wake up and that is the sod refers to)

SOD happened to me few times too with the NO/Hangup button and if/when that happens, if you press NO/Hangup button for long(for the menu with the turn off the phone,reboot,plane mode,...etc options) screen comes back BUT sometimes it locks the screen brightness to lowest possible setting(with %0 actually it doesn't completely turns off as you know).
Other than that "bug" NO/Hangup button works fine for me but as the OP, YES button is more stable and no SODs happen with the YES button...
Btw there is no difference for me YES button vs NO/Hangup button by means of quickness... Both works the same speed unless of course there is no SOD with the NO/Hangup button...
Just wanted to share my experience...

This thread is awesome
Thanks for this thread. I have been trying to use any android build for at least a full day with no success. Ive used different winmo roms and radios such as chucky and miri roms. I still ran into sod's. After waking with the yes/button i have had no sod issues since then, Once again awesommmmmmmme thread.

After some time my digitizer died almost completely. (Issue became worse) It is currently being handled under warranty. (digitizer is replaced)
But at least with a lot of feedback from this thread and other threads, it has come out that, waking up the phone with the YES/CALL/SEND green button is BETTER than waking up with the NO/END/POWER red button for SOD reasons.

any solution to this issue yet because i just started having this exact same problem w/ my HD2 yesterday before that it was perfectly normal and all the suddon the Power/END/NO button wake up cause the screen to not respond to the touch at all however wake up w/ home,back,menu,call button the touch screen works is back to normal
still can't figure out if its a hardware or software problem cause i also tried flashing bunch of roms/radios/and android roms as well and even went back to stock rom in hope for a solution

waking with green is about 2s faster for me.

Same thing happens to me before 2 days.I tried many hard resets,roms,radios and my screen didnt work.I couldnt even login in wm.
My screen was completely dead.The last thing i did,before my screen goes unresponsive was to push no/hangup button in android to open it
At first also i thought it was a g-sensor issue,but then realise that it was much more than it.
Until the moment i read this thread
The way it worked for me
I open the device with no button of course,made a soft reset from red hole and i wait until the device goes to standy itself.Then i open it from send button and voila touch is back !!!!
Strange thing but it works.Thank you very much you are a genius

sure the touch comes back when it wakes up using all other buttons except the power/end button so why is that all the sudden the power/end button causes the screen to go unresponsive
like for say when i hold the power/end key to open the pHONES OPTIONS in windows or android once the PHONES OPTIONS shows up and i try to click on power off or reboot on the screen the touch doesn't respond so the only way to reset or power off the device completely is the either use the reset button in the back or pull the battery out
i'm going to be sending it under warrenty/insurance to t-mobile and hopefully get a replacement cause i'm so use to the power/end button to wake up my device...

Guys be extremely carefull when using hard buttons in android.Finally my problem with screen is not the end button but the back arrow button.This button is necessary for using android and i have pushed it many many times the last months as i am using android.Νοw every time i pushed it my touchscreen stops responding.Τhe last time i pushed it my screen stopped responding(i thought for ever) and didnt knew the exactly reason that this happens.Because i didnt want to send the device to htc (firstly i must send it to expansys in france and they will send it to htc) and take it back at christmas i decided to go to a local mobile service.I wasnot mind for warranty cause i wouldnt be able to live 4 weeks without hd2.I was ready to give 600euros to buy desire hd
Result from service
At firstly he said to me that hd2 have no touchscreen problem and it works ok
I paid 20euros for opening the device and took it back.At first 5 minutes my screen stopped responding again and didnt knew the reason.For my good luck i leave the device untouched 10 minutes and the screen come back again.Then i used it and the time i pushed the back button the screen stopped working,fortunatelly for little seconds.Now i know.My screen stop responding when i push back button.So i change the keylayout to my android build and now i push send key instead of back and volume up key for menu and volume down for power on-off and hd2 works perfect after 24 hours without touching the back button
Also in monday i will go to service again to fix the button problem

Same issue with me
Exactly same issue with me. I have been using Winmo and Android on and off in my HD2. couple of weeks back, touch didnt respond after waking up the device from standby by pushing endkey.
tried everything - flash/stock rom/removed SD card/ hard reset/clear storage/custom rom/ battery pull out etc...
touch worked suddenly and only when i slightly touch the end key instead of pushing it fully, the start menu opened..this happened for few days and when ever i push the end key...screen goes unresponsive. all other hardware buttons are working fine and if at all i push end key the issue starts.
unfortunately my friend pushed the end key once and the screen never responded after this....now am using my old p3450 htc touch...
i think if we change the AP BOARD (Flex ribbon-keyboard chip) everything will go back to normal coz its not the problem with digitizer or the lcd of the software for sure.
trying to order one in ebay, we can change this ourselves...no need to send it to service centers and waste money on it.
if any of you have done this already...let me know if it worked for you.

guys dont know if it is allready known but there is a app called sidebar style swkey
http://forum.xda-developers.com/showthread.php?p=9726110#post9726110 which puts software buttons in the screen.This app is definitely button saver

Strange Touchscreen NAND Issues

ok, I have a strange issue that I can not seem to find the answer to. Whenever my phone locks after not being used etc. When I wake it up, the touchscreen will not let me unlock. It takes me close to 50 attempts to do so. However once I actually am successful in getting it unlocked. The touchscreen works flawlessly. I have tried several different builds, all of them I have the same issue. I have done Task29 and started fresh on that front each time. I tried a couple different radios. Any suggestions?

**** man i got the same problem! i tried hard reset, rom updates, other buils but it wont go away!
plz someone help us!

Hi,I'm using BOYPPC-SHIFTPDA GINGER 2.3.3 RAM_V5 works great so far the best that I tried.After u flash android it's recommended to wait few mins until it loads everything then do a shut down - not a restart.then again u wait few mins and u do a second shut down. after that the os should work fine ,at least for me works great. if that doesn't help ,try to reinstall everything from the start..hspl radio etc.

You could just turn off the lockscreen? Get 'NoLock' from the market. That should do the business if you want.

I've got the same problem since 5 days, It started when I started using WIFI and turning off my 3G ..

you have the same problem my hd2 has....it is a hardware issue. the screen becomes unresponsive. if you still have warranty send it in for a repair. if not... repair it yourself. it's not that hard. the screen wire is probably just loose.
follow this video to take apart your hd2.

Sounds like a similar problem that I'm experiencing. If I wake the lockscreen with the send key instead, it works. When I boot I get exactly one shot with the end key then it locks up again. I'm able to use it with the send key, but concerned it might get worse. If anyone finds the solution please post.

I actually for the first time had this, and I know this is going to get flamed but its not the Screen thats the problem. And I think (BIG IF) that the dreaded unresponsive screen issue that we keep reading about Majority of them I think is not the screen.
I have 2 HD2s and both have worked flawlessly without any problems, but today I was playing with my test phone that doesnt get used that much and I noticed after installing a new rom that my screen after I played with it for a bit went black (sleep) and when I woke it up it wouldnt respond, first thing that crossed my mind is I just lost my digitizier, and started wondering okay why, I went as far to re-flash WinMo stock HD2 rom, same issue, so I decided its time to find out exactly whats causing this, and I found it. I wasnt going to make a post again cause I figured people would be "Not another thread about this" but I know whats causing the screen issue, at least this is my suspicision and I have temporarily fixed mine.
The problem is HARDWARE, The Culprit: THE END KEY (Red Button)! The Answer to "How or Why": The "End" key is used to turn the phone on and off or to put it in sleep mode, it is the most used key out of all 5 keys, it is used probably 7x more then all the rest, Its used for just about everything, now how does this cause the unresponsive screen? Easy, the phone lock or sleep is associated with this key, Its the only way to make the screen go off other then waiting for the time out period. Because by habit we mostly hit the end key to turn the screen off the phone automatically associates this with locking the phone, once that happens the screen becomes unresponsive because of several reasons: 1) The contact under the actual key has dirt which causes the button to stick in the down position, 2) the contact is bent which the "end" key is pressing down on the contact which is making contact with the board and causing it to be unresponsive, 3) The contact is worn. This is the reason why if you press the end key a few times (anywhere between 2-10) and then try the screen responds, this is cause your "unsticking" the key which then lets the screen respond.
Most of us when we hit the end key press to the far right to avoid hitting the back key (The button with the left arrow) which causes the end button to lean toward the right. But you can wake the phone up with the other 4 keys to the lock screen which will allow you to unlock the phone. As a temporary fix for myself, on my test phone I now make sure to press on the left side of the key to prevent this from happening, since its a test phone I'm not worried, but the real solution is to take the phone apart and clean the underside of the end button, and the actual contact with alcohol to remove the build up of dirt and whatever else. And also if the contact frame is bent to GENTLY bend the right side back up alittle to stop it from happening, or sending it to htc and letting them fix it.
We have to RE-TRAIN ourselves to start using the other keys to wake the phone up and not rely on the end key so much.
Hope this helps anyone finally why we have this problem. And if it works for you then hit the Thanks button
