Touch screen not working on HTC TP2 - Touch Pro2, Tilt 2 Windows Mobile General

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.

Hardware problem (buttons), please help.

over the past few weeks some of the buttons (namely left soft key, up and left) have stopped working, i've tried numerous roms just incase but it's definatley a hardware issue, now, i've dismanted the phone using the diamantos guide to see if anything jumps out at me, gave the phone a damn good cleaning whilst i had the chance, put it back together....but nothing, everything seems to be in order, all components in their rightful place but i still cant work it out, does anyone know if this is a common problem or if theres a fix as i've been unsuccessful in my searches.
actually, i just found the solution and it worked a treat, thanks anyway people.
btw, if anyone would like to know what i did then i'll be more than happy to share the solution.

please share your solution with us, I have the exact same problem
ok, no problem, heres what i did.
before you start please be aware that this is a very delicate procedure and you should take care as this may naff up your beloved trinity.
ok, i first disassembled my trinity using the dimantos guide located here http://forum.xda-developers.com/showthread.php?t=311463,
now, when you get to the keyboard / button pcb take it out if, you look closely you'll notice theres a thin adhesive plastic cover covering the metalic buttons, very very carefull peel this back (i used a sharp knife to get to it), making sure not to completely remove it, try to only expose the underneath of the buttons in question, you'll see that the buttons come away with the plasic leaving the underneath exposed, now, using a cotton bud and some lightly applied alcohol clean the contacts then when all is done, replace the plastic and make sure its firmly pressed back down you may notice it making a different, kind of sharper clicking noise when depressed than before meaning its worked, repeat for all buttons.
i think whats going on here is the gum or glue from the plastic film has "leaked" if you will, onto the plates meaning theres no contact from the buttons, this would also account for the very slight change in sound when you now press the button.
i found this info here http://forum.xda-developers.com/archive/index.php/t-289737.html
i have the same problem with the front hardware keys. They last around 1 year, i had them changed under warranty the first time but now they are failing again.
Thank you! now i just have check for tools and some courage because i fear damaging my good old trinity.

....hi to all dear friends!!after half an year of very hard work my trinity has the same problem....only central botton working but,the superior two,works if I do an hard reset!very strange!changing a lot of different roms,from w 5 to w 6.5 the problems doesn't solve...!
- I'd like to make your same operation but I'd like to know first if you too have they working on hard reset before trying....
thanks a lot and merry christmas!
yes, even after a hard reset they work for me, its as if it was brand new, bare in mind you may have a different problem so if your gonna try this, TAKE YOUR TIME.

I tried doing this but found no plastic cover above the metallic buttons. Maybe it's because mine went for repair with this problem before, dunno.
I don't think i can mess with the metallic part so i guess i'm stuck with this unless i buy a new keyboard.
it's more of a very very thin laminate, like sticky back plastic than a cover, it should definately be there unless they replaced the PCB with a different model, otherwise the metalic buttons would just fall away. Again, they may have used a different version of the PCB. You can actually buy the PCB and replace it yourself. (here http://cnn.cn/shop/p3600dopod-d810-keypad-p-1825.html )

TP2 Screen not responding

Hey Gang!!
My Tilt2 (TP2) was acting sluggish the other day and then the touch screen would not respond to anything.
I did a soft reset ... didn't work or solve it ... so I just went ahead and did a hard reset. Even after doing that I have no response from the screen.
The screen shows up everything .. I can view the time, people calling me but it just won't pick up any touch activity at all.
Has anyone ran into this ? or what would you suggest.
Just need some help !!
Thanks !!
TarkuS
I just got the same problem. Wich rom are you using?
Just what came with it from AT&T ... factory settings back on it now.
6.5 winmo
had never put a different ROM on it.
Your digitizer may be dead and in need of a replacement
I just got done searching something's from google and other people who have had the same problem and tried one thing.
The outer rim where the chrome area is , they said to clean or see if there is crap/crud in between the screen and the chrome area.
I did that and it seems to be working ok right now. Just have to be careful. I used my thumb nail to slide in between that area but you might want to use something thinner to be on the safe side.
Thanks, that worked for me also. bit strange solution but isf it works...
the crud you collected must have been pressing the digitizer down in multiple spots or even just ONE spot which led it to think there was already a "touch" on it.. hence not working when you would touch it else where.....
There's been issue's with cases doing that where they are too tight and the screen is picking up that pressure as a 'press'... it's odd you guys have collected that much stuff to make the screen act funny though... messy pockets for sure!

TP2 screen not responding.
Thank you. Cleaning around chrome area worked, but I lifted the plastic contact a bit, so future users of this method should be careful. The contact lifted above the buttons on the bottom of screen, so I will have to be cautious not to get dirt in further.

Touch screen has stopped!!!! Help!!!

My phone has been going great and giving no issues. Byt the other evening suddenly the toicuh screen stopped being responsive!!! Totally randomly. No drop or spil or anythign like that, no new software or roms recently.
When you open it the keyboard still lights up, and after a hard reset, you can navigate a bit using the keys. But ZERO response from the screen!!!
As i say, this is even with a hard reset!!! I also tried using masking tip to pressure the screen in case somethign was stuck.
Ok it mighty be the digitiser, or a loose connection. Im hoping not.
Has anyone experienced this or similar and is tehre anythign else i can try before i take the plunge and get someone to look at it??? (its out of warranty unfort)
Ouch
Sorry to hear. It happened to me months back. It started with very uncalibrated clicks... making corner clicking impossible to compensate for.
I've recompensated, but that didn't last long - and it eventually degraded to no touch screen. With insurance, I did get a refurbish for my woes.
I flashed Stock ROM and relocked. No luck.
I'd still back up everything.
Reformat SD card.
Reflash stock ROM
Relock the device - all to see if it helps.
I did have a similar recent problem - but in this case it's because I was using a clip on hard case front that must've been putting pressure on the touch screen.
Hopefully one of these helps you out. Good luck
When my screen stopped responding it was due to a more physical thing.
I read this somewhere and tried it, worked instantly!
You have to get your finger nail under the screen (try pushing your nail into the edge of the screen from the side) and lift the screen up a bit.
This worked for me. If you think its a physical and not software issue give it a shot.
I have had the same problem.
I bought new touch screen on ebay (about $15) and after replacement the device works well.
stop everything !!!!!
if you have Google G Mail set up on your phone remove it and it will fix it's self
somthing google / G mail is doing the tilt 2 doesn't like
causing the "Sleep Of Death"
Hi guys
I have tried all the above
Last resort is i got sprite backyup to work
BUT HOW THE HELL DO YOU HIT "NEXT" OR "OK" FROM THE KEYBOARD AS SCREEN DOESNT WORK????

Below is one more post on this topic from another forum:

It's actually very simple to fix - slide a finger nail under the plastic by the speaker and gently pry the digitizer up. Then, put it back. You dont need to remove it totally from the phone. It will flex back to its flat shape as soon as the glue releases. As soon as you stick it back down, the touch screen will work again.

[Q] screen stopped responding - bad digitizer?

For the last day or so the touchscreen on my Tilt 2 will not respond. I thought Sense was hanging due to text messages so I deleted all of them this morning. That didn't help and neither did multiple reboots so I finally did a hard reset. Now I am really hosed since I can't get through the initial setup. Sounds like the digitizer may have bit it?
I am not at home to flash an official ROM right now but I will try that tomorrow. Other than that does anyone have any other ideas? I am paying for the warranty and insurance so I think I can get it swapped if I have to. Are they still sending out Rhodiums or do they have another device to send in its place now?
Okay, I just flashed the latest official ROM downloaded from HTC. Screen still isn't working. :-( Guess it's time to contact Asurion.
my tilt2 is also doing this, it stopped working about a week or two ago, then started working a few hours later. lately it will work sporadically and most the time not how it is supposed to. i have simplicity. i also have the insurance and i think mine is still under warranty, will i need to put the original sense back on it b4 i send it back in? also, on another note, sometimes when i plug it in to charge it the orange light doesn't come on indicating it is charging, i have to hold the power button for a few seconds. it started around the same time, are these issues related.
Possible fix
Ok, so I have learned that these screens are pretty sensitive, especially if you put them in your pocket. You can sometimes revive this by sliding your fingernail into the seam along the outer edges of the screen and running it along the seam as if you were trying to peel the front (digitizer) off of the LCD. It somehow releases the stuck screen or something. Mine has been doing this off and on for a while and I've been able to revive it several times with this method, though it's getting too frequent now and I'm thinking of trying to replace the digitizer all together. I'm afraid to make that leap though.

The reason this "fixes" it is there some dust or dirt between the screen & panel. If enough gets in there, the digitizer gets confused and ignores any presses.
If you completely disassemble the screen and thoroughly clean it, I bet it'll be fine - no need to replace anything. However, this is a very tedious and delicate process, so be extremely careful.

[Q] Replaced broken screen, thin line on screen unresponsive

Today I finally decided to replace the broken screen on my Nexus 7. Everything went well and according to plan, and when turning on the device I noticed it was working fine. However, upon closer inspection it turned out that one thin line on my screen isn't working. It's preventing me from doing SwiftKey flow, and when I tried drawing in Evernote I could see it was skipping over that part of the screen.
What could be the cause of this? I can't rule out that it's the screen part itself, but could it be more likely that I somehow damaged the LCD flex cable? I tried detaching and reattaching cables, so I have doublechecked that. I guess my question is mostly, how useful is it to try and replace the cable? Thanks in advance!

Did you replace the combo lcd/digitizer, or just the digitizer? In the latter case, you're lucky to have just a thin dead band; usually,1/3 of the screen would be unusable. In the former case, if the bezel is bent, however slightly, or there is some glue residue from the old screen on the bezel that causes the new screen to lie on an uneven surface, it would happen. I've experimented enough times to know the bezel has to be absolutely clean of everything and the surface must be 100% smooth and even. If you used strong tape on the new screen, your best bet is the multi-fix touch, as removing it would in most cases damage it.

I replaced the screen + digitizer. I looked at the bezel (luckily the tape I used wasn't that strong so the screen was still detachable) and I cleaned it up thoroughly. There were indeed some glue residues left. However, it was no use, the screen still fails in the same locations. I had high hopes this might be the cause, but apparently not.
I highly doubt the bezel was bent, because I was very careful with it. I will try out the multi-fix touch option, but I'll do that tomorrow as I'm quite tired now. Thanks for all the suggestions!

Don't know if you're familiar with the mechanics of the touchscreen, so I'm adding this for the sake of completeness. Lots of people would post problems and when you try to help, would snap back: "I already tried this and that and other things..." So if you already know, forget the rest.
I've found Yet Another Multi-touch Test (YAMTT) of tremendous help in diagnosing. When you switch from one firmware to another, YAMTT allows you to pinpoint exactly where touches do not register. If the dead band remains consistent, it's probably the screen itself. However, touch detection sometimes varies with the speed at which you touch. I've seen touches missing in some areas, which would register on a second or third or fourth pass. So, go slow in those areas, and back and forth to make sure they're really dead. Tedious process indeed, since you have around 30 variants to play with.

I took a look at that tool, and I posted the result of drawing on imgur: paste "oyIt3bg" after imgur.com (I'm apparently still too 'new' to post links, sorry about that). It is clearly one band, very consistent. I think I should probably talk to the shop I got it from and ask for a replacement. Which sucks, because this particular parts took 3 weeks to even get here. Anyhow, glad I know what the problem is now. Again, thanks for all your help, I appreciate it
Hello fellow dutchie,
I have experienced this problem on my Nexus 4, and after having replaced the LCD+digitizer I also had issues with touch responsiveness in exactly the same areas. As silly as it would sound beforehand, it doesn't seem to be the screen or digitizer. Best... to give up.
