Touch screen not responding - HD2 General

When my HD2 returns from standby (switched on by the right hand button) the touchscreen is sometimes unresponsive. At first this just seemed like a short delay so I ignored it but this week it has refused to allow me to unlock it. The screen seems to be frozen.
I have tried turning the HD2 of and on - not completely off as I can't get to this function without being able to use the screen - and if I do this enough the screen will suddenly become responsive. The problem even survives a soft reset.
Yesterday, I decided to do a hard reset thinking I have done one reg tweak too many. After that the screen seemed fine and I could return the HD2 from stand by okay by sliding the 'lock' button. This morning the problem has reappeared and I again find that the screen will not respond to touch but then suddenly seems to work.
Anyone had the same problem or have any suggestions?
Thanks

I have the same problem as you on my brand new HD2. Did you allread have a solution for that?

folks, do report your issues here .. i have a feeling that this is a known hardware issue by HTC and they are just keeping veru quiet about this.

funny screen problem?

Hi everyone,
I'm experiencing a very weird problem, with my Trinity (actually a p3600i).
When I'm using my thumb or fingers to type on any SIP, sometimes the start button is pressed even though I'm no where near the start button!
I'm not sure if it's happened when NOT using SIP.
I've noticed that it only happens when using my thumb/fingers. If I use my nails to type the problem never happens. Same when using the stylus, no problems...
Anyone know what is going on here? It can be very annoying sometimes.
Thanks for reading!
OK I just made it happen when just in the today screen.
Doesn't just happen when using any SIP...
Happens when I'm tapping in the bottom left region of the screen in portrait mode.
you are not alone
have the same problem, occurs couple of times a day, and as you noticed when using fingers. we are not the only ones, many (really!) trininty users report the same problem. finally it may result in widely known problem related to flickering start menu button and irreactive touchscreen.
i noticed one more thing: when you disable sound for screen taps from sounds and notifications menu the erratic reactoin seems to go away, not completely, though because i still manage to cause false start menu activation by chaotic screen tapping in phone mode.
read this topic, sorry to disappoint you but imho this is our nearest future

looks like i will need to send it to them for repairs
and nothing ever returns back the same, when it goes to get repaired

Hanging at "Align Screen" screen? :(

Hi all,
Like many people's, my Hermes (T-Mobile Vario II) suffers from screen misalignment issue, and needs re-aligning almost daily. I've done all the mods but to no avail. It is out of warranty so I can't send it back.
Recently, when I try to align the screen (by pressing Confirm button + Message button, or by going to Settings > System > Screen), it just hangs in the "Align Screen" screen - it does not respond when I tap on the target cross.
Only a soft reset can take me out of the screen.
I am using Schap's January 2008 version.
Any idea why please?
But screen now is misaligned really badly and I can't re-align it...
Thanks.
EDIT:
But it doesn't happen every time. Very occasionally it would work...

Answer is easy... Schaps roms have "Ftouchflo" installed. It is nearly sure it is activated on your phone. In this case, the alignment utility is NOT usable. And the pda can stay with a non reactive touch screen till next reset.
Desactivate touchflo by using the touchflo configuration tool followed by a soft reset. So you will be able to use screen alignment.
Just tried and yes! Thats it!
Thanks a lot matey!
You are welcome
Perhaps this should have it's own thread but it is very similar.
My tytn (WM6) has suddenly developed a strange problem. When I go to align the screen, the crosses appear as normal and when I point to them, it appears to be working. Except... After pointing to the last cross, the whole thing starts again, and this happens continuously!
This started when I applied a screen protector and tried to align the screen through it. It was working fine before then. I have taken the screen protector off again, but there is no change.
As I've spent the whole day installing cab files and getting it as I like it, syncing etc. too, I really don't want to have to hard reset it again.
Any other ideas?
That usually means more than 1 point is touching the screen.
That's what I thought but I've cleaned the screen and done the business card trick all round the edges. I can't see where it could be touching...
Any other ideas or suggestions that may help?
I couldn't find a touchflo "disable" button anywhere on my Hermes, but I did go into "Remove Programs" and uninstalled the HTC Cube application, then did a stylus soft reset, then aligned the screen with no problem.

strange keyboard problem

I experienced something strange with my Qtek 9100 today. when i turned on my phone, all the keys including the call and the 'hang up'-button where backlighted. the keys did not respond as they should, and pressing the d-pad center would either open the start menu or initialize the screen calibration. if i opened the Notes app and created a new note, the note was filled with single letters like the L, the H or the Y. none of the keys seemed to be working when i pressed them.
i've experienced this once before, and the only thing in common is that i had my phone in a thight pocket for several hours. last thime i solved the problem by hibernate the unit and pressing all the keys, and turn it on again. this time it wasn't that easy, but i managed to get it working again at last.
but why is this happending?
PS: i've tried soft reset and taking out the battery, and that didn't help.
Please help me and my phone

[Q] Touchscreen works only until screen is turned off for first time

Hello all,
I have a problem with my HD2's touchscreen. I've had the phone for awhile now and never had any problems. I've been using android from Sd for awhie and recently switched to NAND android.
I go to bed with a working phone and when I wake up, the touchscreen doesn't work. After trying to use it all day, it occasionly works. When I receive a call or text, the screen works just fine. I am abe to use it until the screen turns off then no more. This happens for each call or text. It also works just fine at first boot(until the screen is turned off.
Thinking that this was a software problem, I tried flashing different android builds, with the EXACT same results. I then wondered if it was a problem with MAGLDER, so I flashed back to a STOCK TMOUS rom, and stock SP, radio etc.
Even after going back to COMPLETELY stock, it now does the same thing in WINMO. Works just find at first boot until screen goes off, and works when I get calls and texts.
I'm now thinking that this is a hardware/digitizer problem, it just seems weird to me that it works 100% until the screen goes off and then not at all.
Anybody have any idea's or insights?
Thanks!
i've read a few similar threads (please search for them!) that indicate one possible cause...
your buttons strips at the bottom may be messing with the touch screen connections. i remember reading in one thread that the dude found a strong relationship between use of the on/off/endcall button and touchscreen failures.
you say it works...:
1. ...until the screen powers off
2. also works when you get an sms or call
in case (1), you have to press the endcall button to "wake" the device...so maybe the button puts just enough pressure to screw up the screen.
in case (2), the device wakes up automatically, so you never pressed the button that might cause the screen to screw up.
try to narrow it down like i've described. maybe your buttons are causing the problem. good luck!
Thanks for replying!
I did see the thread you were talking about though it did not seem to match my problems. However, today as I was working and pulling my phone out, It has started to look like that is the case. As of this afternoon, as long as I press any of the buttons other then the power/end call button to turn on the screen, the tuchscreen works just fine. When waking up the screen with the power/end call button, it does not work at all.
Yesterday and this morning, it didn't matter what button I pushed to wake up the screen, it was totally unresponsive.
So it looks like using the power/end cal button presses on my digitizer and causes problems.
And it's back to not working at all when I use any of the buttons, lol. Guess it's time to start looking into a new digitizer.

Screen blank on power on

I've had a problem with my E900 since I got it with regards to the screen. I was hoping Mango might fix it but it doesn't seem to have.
Sometimes if I press the power button the screen backlight comes on (i.e. screen goes from off state to powered) but there is nothing on the screen. No amount of button pressing will cause the screen to show anything.
If this happens I have to turn the device off again (backlight then goes off) and try again. Sometimes it can take 2-3 times before it turns on successfully with the lock screen.
I also have this if an incoming call attempts to wake the phone and also alarms too.
Does anyone else have this issue?
I confirm this one popping sometimes. Not that often that it becomes annoying, but nevertheless.
Did you find a solution to this problem? I am experiencing it too and it is very annoying!
I've recently inherited one as well (E900 that is).
The one I have has been dropped, the backlight powers, but no drawing on the screen.
I've disassembled and re plugged everything (bugger stripping down!) but still no luck. I've done a VolUp+Down+Cam+power hard reset, and when I plug into PC Zune says setup needs completing (so it has reformatted) but still no luck.
I cant see anything fried, and no damaged ribbons as far as I can see, any ideas?
I sold the phone a while ago, and never solved the problem. I think it's a firmware issue.

hi.
What do you mean "somethimes if I press power button"?
Is it pressed with purpose to lock the phone, press it to turn off phone (background slider shows to power off - on Mango and beyond version) or press it accidentally?
Cheers.
So, I did a phone reset. Unfortunately the issue is still present!
Sometimes when I press the power button to unlock the phone the screen is lit, but stays blank i.e. no lockscreen wallpaper, no nothing. The same happens sometimes when I get a phone call - the phone rings and vibrates, the screen is lit but stays blank.
When this happens I have to press the power button to put the phone into sleep mode and press it again to wake it up.
What I found is, when the issue occurs the screen is actually responsive. For example I can slid up and unlock the phone then I hear the unlock "pop" sound. It's just that nothing is drawn on it!
I was wondering if anyone else experienced the same behavior and found a resolution. Also I am not sure if this is a software or a hardware problem. If I could confirm it was a hardware problem I would call LG and have the phone repaired or replaced.
i have exactly the same issue as you, it gets really annoying.
i heard from someone online that the only way to resolve it is to replace the motherboard

I am pretty certain this is a hardware issue. I am calling LG tomorrow and hopefully they'll take the phone for repair/replacement.
I sent my phone for repair. Today I got it back, and guess what?!
The issue is still present! It seems, they "couldn't reproduce" or something.
What should I do now?
EDIT: If anyone is interested, here is a video I just captured which clearly demonstrates the problem. http://youtu.be/38kF9RYs_bU
I'm sending the phone back for repair tomorrow with this video attached.
Hey, might not be an issue at all, but in the video, I saw that the two times you were able to get it to go blank you had your finger on or near the proximity sensor. I wonder if there is something that could be the trigger.
Just wondering if you can duplicated it or cause it only when you have the proximity sensor blocked, or if it truely is random.
You are right, it might has something to do with the proximity/light sensor.
On the other hand, this issue occurs even on incoming calls when the phone is placed on a table, screen up and nothing around the sensor.
Today, I visited my local carrier shop and left the phone for repair again. They told me, since this is a second claim they'll run it through the process faster, so I expect to get it back next week.
Will post an update.
UPDATE: My phone was replaced. Yesterday I got a brand new unit, yeah! It was stock wp 7.0. I plugged in my sim and used the phone the whole day, no sign of blank screen issues. Last nigh I installed all the updates (total 5 I think) up to OS 7.10.8107.79, FW 1.0.16.10. Guess what?! Same issue!
I am crushed
