tapping problems - touch screen is not working

Using my htc device suddenly touch screen went off and i could'nt use the stylus at all. The strange thing is that all of the other keys are working good. I tried hard reset the device but nothing happened. Now im stuck in the screen "tap the sreen to set up your windows mobile based device. Can anyone please help? Before the appearence of the above problem i was using google maps, if this helps.
many thanks

Does t have a crack in it? If so then it needs changing, if not then probably the ribbon has come out. Is it under warranty?

no there is nt any crack! everything was good and suddenly while i was tapping to check some maps, stopped.
Sorry for asking but ribbon is that thing above the screen? Is it possible to come out so soon? (6 months). and finally does the warranty covers ribbon change?
Sorry for the above questions but i really dont know what to do!
many thanks

call the company where you buy it from and ask them

If it's only 6 mths old it shoud be under warranty, so take it back to the place you ought it.
If you are determined to try to fix it yourself you have to do the following.
Remove the battery cover & battery.
Remove the 4 small screws
Remove the back-case by running your fingernail round the gap (hard 1st time then easy after that)
Remove 4 more screws
Remove front-case from the middle
Remove the motherboard assembly from the front case and unplug the screen/digitiser assembly, carefully pull that off the motherboard (again not easy 1st time).
You will now see the small digitiser ribbon at the bottom coming off the digitiser and disappearing into the bottom of the screen. It's very easy to take out and not easy to put back in. I use some flat-bladed tweezers to do mine but sometimes it takes a couple of tries. Obviously it's much easier if you are fitting a new digitiser because it's not fixed to the screen like yours will be. If you try to remove the digitiser chances are you will crack it. I re-fitted mine after removing my broken one by using thin cut strips of double-sided tape.

Before you do anything else, just clean with sharp knive or razor between the screen and the cover.You will be surprised how much rubish is is in there.
this things are keeping the screen pressed.
Hope it helps

many thanx 4 the instrustions guys. i'll try that. if everything ok i'll inform you. if not i'll give you my bank account number to deposit money in order to buy a new one.
many thanx again

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.

I'll be more than happy

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 )

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.

Is krazy glue conductive or something?

Hey guys,
I tried replacing my DINC digitizer again and everything went smooth until I booted the phone up. The middle of the touch screen doesnt work very well. I checked the cable to see if it was loose multiple times but that didn't work.
So I took the whole thing apart again and looked at it closely and realized the Krazy glue I applied was applied on the side roughly where the problem lies....
Is it possible it is messing with it so that it is detecting a touch there or something? I used krazy glue on there because I thought it would be like plastic.
Or is this just impossible and the digitizer I ordered is defective? It works besides the middle section of the screen.

on the contrary superglue is insulative which could also be the issue since the digitizer needs to be grounded not sure what it is like under the digitizer but is the area it gets glued to kinda metallic if so that could be your issue if not then it could be a bad digitizer i dont think i would have not used superglue i would have used double stick tape or something like that... or hell with how my case i have on mine is designed i would not have used any adhesive just left my case to hold it onto my phone incase it ever got broke again...

Hmm, ah so perhaps it is just not allowing that part of the screen to be sensed.
In any case, I replaced my "new" digitizer with the old one that is slightly cracked for now. I used krazy glue and it worked perfect this time, but then again i was careful with the application.
I will clean off the "new" and try one more time, but I suspect now that the "old" is working so good that it was in fact a defective one.

sorry to thread jack, but since there is discussion already started, I have an slcd dinc, can I directly swap the amoled screen into it? Would you guys happen to know?

it will not work. the board requires different drivers and i think a different power output. (i could be wrong) but its like if you bought a plasma tv and swapped for an lcd panel.

kind of figured that. thanks makes sense.

[Q] T999 back and menu buttons with new screen

I have two Metro PCS Samsung S3 phones (T999N - same as T-Mobile from what I understand). I have had to replace a cracked screen on both.
The first one was replaced with a new OEM kit including preassembled back and menu buttons. I had no issues with this screen.
The second one was replaced with a refurbished part. It did not have the back and menu button pre-installed. Well on this one, the buttons don't work and don't light up. I tried the old buttons as well as a brand new OEM button part. I'm now on my second refurbished screen assembly. Still no buttons working. I have confirmed that the rest of the phone is OK by switching to the other screen with working buttons.
Am I doing anything wrong? All I'm doing is plugging in the button flat cable and making sure the crossing line lines up with the line on the motherboard. After doing so, I would expect them to at least light up - but nothing...
The way I see it, either I'm doing something wrong, I got two bad parts in a row, or the screen assembly is not compatible although it looks right and works in all other ways.
Any ideas?

If the assembly does not include the middle housing, you would need to first remove the old, broken screen (not very easy to do), and then using a special adhesive tape, secure the new screen in place of the old. After this, everything should work pretty well.
There are two "pins" on the mother board close to the usb port that need to connect to the housing for the home button to work.
There are tons of videos on screen replacements on youtube. I suggest you watch a few of them to get a better idea. Feel free to ask here too though. There is also a Glass replacement thread in the General section. Not exactly the same as your problem, but there may be some info there that you may find useful.
Good Luck!
