Touch screen not working on HTC TP2

So the touchscreen no longer works on my phone. So that pretty much means i can't unlock my phone, which means i can't shut it down, which means it's useless.
During startup, i got the very generic services.exe error, which leads me to believe that since there was an error with the exe, the service used to poll the touchscreen isn't running.
So before you ask:
- I have power cycled the phone several times (still same result of nothing
working)
- Windows Mobile upgraded to Verizon's release of WM 6.5
- I have not installed any new software in over a month
- It has never gotten water on it
- I have hacked the registry, about 6 months ago when i got the phone
- I did mess up one of the registry keys, replaced the key name with a
't' and couldn't remember what it originally was, but the phone hasn't
acted up. Can't remember what the location of key is either, but i
was trying to remove the vibration whenever you touched the
screen. There are two locations for it, and i eventually found the
proper one though.
So if anyone has any ideas short of hard-resetting the phone, please let me know. Is there any sw that can run my phone via the computer?
Thanks

Touch screen not working
I have to got the same issue, ever tryed hard rest.
flashed new rom. still nothing...

Solution
Okay, I've just had this problem with an HTC Touch, and I think this works with any HTC that has a "digitizer" rather than an all-in-one touchscreen (I think newer phones have digitisers).
I'm not sure if this will always work, but I've just done it - sometimes the inactive touch screen is "broken" because the layers are stuck together (so the phone can't tell where the touch is, hence unresponsive). With mine, I looked at the screen side on and could see a kind of "oily" patch in the light.
The solution is to get masking/gaffa tape - the very sticky brown one. Stick it down on the screen/digitizer and then keep pulling it off - this pulls the layers from each other. I kept repeating this lots before it worked - and in the end I pulled the top layer completely off (I think you should pull from the top of the phone, as the layers need to be attached at the bottom of the screen/digitizer). Once it pulled away, I gently lay it back down (after panicking!!) and hey presto it started working again.
Good luck!

I have the same problem, oily stuff migrating from a corner inward....
And you're suggesting we do what now? I'm not following this.....

He suggests you put masking tape onto your screen, to pull the stuck layers apart. If this doesn't work, you can always replace the digitizer.

I've done the same, just to thank you.
had this problem this se xperia x2

Unbelievable...this just worked for me too! I gave up on this phone 6 months ago...now back to flashing ROMS, yeah!
Thanks a lot!

It is now!
Thank You! And I didn't even have the proper tape, just some cheap sellotape...did the trick though!
Thanks again, You Rock Dude!
Very Much Appreciated!
(And a Big Thanks to Andrew for the heads up!)

If I had read this 3 weeks ago i wouldn't have wasted 35$ on a new screen.
It gets worse, the new screen doesn't work. But this 1cent fix DOES.
The new screen was never calibrate-able.

I have exactly the same problem! The touchscreen of my xperia mini is not responding at all!
Can you please be more precise? What do you mean "pull off the layer of the screen?" Do I need to disassemble the phone and mess with the hardware? That sounds pretty scary!!!

I think he had some sort of a screen protector that was interfering with the screen...
You can try to run your fingernail along the edge of the screen - between the bezel and the actual touchscreen. Quite often something stuck in there is causing the touchscreen problem (or there is a deeper hardware issue and the touchscreen is just not functional).

I'm in the same boat. Normally I wouldn't be afraid of a little digitizer replacement. But on the TP2 it looks like every single bolt and screw needs to be replaced and in the only video I could find about it, the guy broke the lcd in the process.

Hoolexer
W0W.... You are awsome,,, Now I can sleep at night. Thank You So Much

salterlee you are a genius. I just had this same problem. I putted some masking tape to the screen, didn't had to pull the front layer out, and it worked wonderfully.

A little suction goes a long way!!

Same thing here.
I used a suction cup from my bathroom mirror that held a razor or something and made sure it was decently moist so once i stuck it to the screen i could slide it up and down the entire surface and worked like a charm..... no tape to throw away.
thanks for the inspiration cause i was gonna make this touch into a throw.

Display only on one side of screen?

Hi
First time poster here but long time lurker. My friend has tried to replace the screen on his HTC One X (LCD and Digitizer) and has turned it back on and the screen now only works on the left hand side only.
See photo he took attached.
He has asked me to take a look as I fixed my DesireZ screen before, but no idea how the HTC One X goes together. I had a look at some YouTube tutorials and it seems similar, but I'm unsure whats broke, as it appears that half the screen is working, so therefore I guess its the LCD rather than the digitizer? or is it something completely different or a loose connection?
Anyone any ideas?
Thanks in advance!

It looks like the LCD connection is messed up. Try swiping on the side of the screen that is black, if it responds then the digitizer is fine.

Thanks
He said when he presses on black screen it still responds, so is it just LCD that needs replacing?

Great, thanks

Had a look at the phone today, LCD is broke but also the clip which holds the LCD ribbon in place. Anyone any ideas if this is a part I can buy?

Screen problem

Hi everybody I have a question regarding a screen problem I have.
Like I mentioned in an earlier post I accidentally spilt a lot of pure alcohol(the kind you use to disinfect a wound or something) on my HOX.
After a while the phone screen showed some strange grey shape on the lower right part of the screen and a bright white long shape looking like water jumping from a fountain on the left side starting from the bottom of the screen extending to almost the middle of the screen.After turning it off for 8-10 hours they grey shape dissapeared and the white remains and it doesnt look like it will ever go.
Strangely enough the HOX has no problem everything is working but I noticed that some apps are working somehow over the white shape covering it and some others like facebook seem to be under it making it visible.
I made some screen shots to show you the problem but stangely enough this white shape is not shown at all in the screen shots!!!!
Can anyone tell me where this thing might be?
LCD? Digitizer? elsewhere?
HTC funny enough suggested a factory reset to solve this and if that doesnt work(like there is a chance that it will...) to just send it to service.
I plan to play dumb to service hopping to fix this under my warranty as the phone has absolutely no scratch or anything anywhere as I never even dropped it once.
Do you think they can somehow find out what happened of maybe they will fix it under warranty?
Thanks a lot for your time reading this and I d love to have your opinions

Any photo?
Perhaps some alcohol got stuck between the lcd and glass...

Looks like overheating damage by a component beneath the screen, possibly something reacting to/affected by the alcohol.

When you say beneath the screen do you mean beneath the LCD as well or just beneath the glass?
I am just thinking that if its beneath the LCD it would probably not show plus the phone would have some kind of functional problem(it works just fine) wouldnt it?

Beneath the screen assembly. It looks like (possibly) some component or board has caused damage to or affected the digitizer, as your actual display seems ok.

So the service corrective action will be a screen assembly replacement or you think that something more will be needed?
Also if the digitizer was damaged wouldnt the phone use be affected?Cause the device has not been affected in anyway.
Everything works like it used to before this damage.

Send it of for repair, youll have to pay of course, how much tdo you like your phone?, that's the question.

I like my HOX very much otherwise why would I pay 428 euro to buy it?
Of course what makes the HOX stand out of the samrtphone crowd is the amazing display so of course I want it fixed.
I will try to cheat saying I know nothing about it(the phone doesnt even has a scratch) hoping waranty to cover this but if this doesnt work I ll have to pay 196 euro for screen replacement.
Although appart from that mark nothing else is affected I am worried that perhaps a screen replacement might not be enough if the digitizer is affected by something beneath it.
Do you think that a screen replacement will be enough to solve this problem?

HTC will give you the digitizer and LCD, especially if you end up paying, which will then get you a new bezel and unibody all still tapped up in protective coat, I've had it done for my phone, 160gbp.I even think you get the Onex+ version screen, gorilla glass 2.Could be wrong

[Q] Touch screen madness

In the past month or so my Dinc2's touch screen has become increasingly erratic. I don't think it's the screen itself, because anytime problems arise, a quick off and on of the display will fix things. However, the problems seem to be centered on the bottom section of the screen...weird.
The problems I'm talking about are unregistered presses, pressing one place and something happening in another place, presses happening without any contact at all, etc. For example, sometimes I won't be able to drag to unlock, but when I turn the screen off and on, it'll work.
I'm thinking (hoping) it's a software thing. I'm running CyanogenMod-7.2.0-vivow. Are there updates to this ROM? Should I just try another ROM?

Looks to me like a faulty digitiser. But try wiping and refalshing. It won't hurt. Good luck.

After wiping, should I flash a fresh version of the ROM or restore a backup?

try wiping and flashing without restoring. start fresh. if it works, then you can look int restoring.

Didn't work. Any other ideas? Not sure what this digitiser thing that you're talking about is...
EDIT: Ahh...it's hardware. Well, crap. Is there a cheap way out of this mess?
I found an "HTC Droid Incredible 2 Tough Screen Digitizer Replacement." $24.99. Is this the solution?

If you truly believe it's the digitizer, then yes, that's the way to go. I warn you though, the digitizer is glued to the LCD so you need patience, a light hand, and a blow dryer with low heat setting. I replaced one myself and managed to make a small spot on the LCD where I must have accidentally flexed it a little.
Back on topic, I believe I'm having the same issue with an Original Incredible. I turned on a developer option that registers screen presses as dots on the screen and I have two, almost constant, finger presses in the upper left middle of my screen. I'm thinking it's the digitizer, solely because the presses also occur in my TWRP recovery. Lucky for me, the digitizer is only attached to the front housing of the Incredible, so I just have to purchase a whole new front housing with digitizer attached. Best of luck on replacing the digitizer if you go that route, but you may as well want to invest in the whole screen + digitizer package if you can afford to.

Thanks for the info! Is it relatively easy to turn on the option that shows screen presses?

[Q] Screen artifacts

Hope t his is the right place to post this. Just replaced the glass on my TM217A and now have "blobs" on the display. What did I do wrong? Any way to fix it? They are on the LCD panel itself, noticed them when I turned the tablet on after remove the old glass and before installing the new.

it looks like you bent/deformed the part,
you mean the digitizer right ?
as to fixing it, you may have to get another replacement.
those bubbles are probably sealed in now. you could try remove the part gently
and clearing away the adhesive to let the air [which is what it looks like] escape,
and try again.
