Guys really need help! WHO CAN COME!
In short there is a given device a3000 H
Crashed native touch, bought a new one.
At first I did not notice the defect and took off the warranty tape.
There is a problem, the touch itself does not work.
When the display is on, I jiggle the cable and voila the touch works!
But if I lock and turn on - then the touch does not work!
I can not understand what the problem may be!
And when when I load the phone I distort the loop, the sensor works at start-up.
And also when I lock and unlock it does not work ...
The feeling that when you turn off the screen or the tablet itself, what is the signal does not reach and the tach does not plow!

I'm sorta new and not exactly sure how to submit questions.
I installed the SPB mobile shell on my elfin htc and now the touch features don't work and my phone won't sleep without what appears to be the backlight on. Can someone provide some directions on how to fix this? Can't get to the bootloader either.
if you reset your device, can't it boot up into windows mobile?
if it boots up, why not connect it to the pc and try removing the last app through activesync?
if there isn't anything that important on the device, did you think of a hard reset?
Thanks for the quick response, however, I did do a soft reset, the screen is not responding (completely frozen). I've already removed the program, I thought was the culprit (spb mobile shell). I did a backup, but without touch features, I can't restore backup. I can't do a hard reset that's not working properly either. Any additional ideas, I'm at a complete lost.
Hi
Touchscreen of my HTC Touch (P3452) stopped working. I tired following:
- hard reset
- hard reset successful, then It asked me to tap the screen for alignment then I tap, it worked but on Calibrate screen where you align your screen touch is not working. nothing is happening after that even power button is not working. my Touch is not hanged coz if I touch the screen after It goes to sleep, the backlight will turn on.
So I though may be something wrong with the original ROM, then I tired flashing it with cooked ROM's but nothing worked.
I am still stuck at calibiration screen
-
Plz help, I miss my HTC Touch (P3452) so much!!!
If your touchscreen is not working, there could be only 2 solutions.
- Get a digitizer off dealextreme.com
- Hard reset device.
my $0.02.
Cheers.
What's a digitzer and what does it do? I've looked in cell phone accessories and did a search on dealextreme.com, however, unable to locate such an item. Can you provide a little more detail. Desperately trying to get this phone to work and right now this appears to be the only solution. Hard reset isn't working.

Come on, Google man!
http://www.dealextreme.com/products.dx/category.506~search.htc touch digitizer
Digitizer is a 'panel' which is above the LCD, which senses where your hand is at on the phone.
Something like this:
http://en.wikipedia.org/wiki/Graphics_tablet
It is just something which sense where is your fingers are in the touchscreen.
Hi toot-b:
I had a similar problem a few days ago. My screen stopped working completely. I gave it a few taps and a squeeze and it started working.
After a while it stopped working again and did not respond to the squeezing too. Then out of desperation, I tried searching the internet. One guy had given the most idiotic explanation I've ever come across.
He had advised to take a blade and peel away the LCD screen and after taking the screen away, to rub the copper contacts with the blade and then putting it back in!!!
Well, I was really really desperate and I had to try it. I didn't remove the screen completely. I just took the screen off a wee little bit on the bottom right corner near the camera button. I kinda got scared after that and put it back in.
To my surprise, the touch screen started working perfectly and till now its doing great. Try it at your own risk. All the best!!!!

Hey there!
my friend has one of these HTC Touch, accidentally it fell on the floor when she was partying..
the display broke down... I changed the display but it works like 5 minutes and than it says that it needs to be calibrated, so we perform the calibration, but at this time I can´t even pass through the calibration. Have to do the calibration a couple of times and than it works fine again...
another time it when I tried to send some sms another calibration request came out, but this time it worked again after first recalibration..
It´s not very user friendly when you have to do the display calibration again and again....
Please any solutions??
touchscreen is probably loose because of the fall
try pushing the sides of the screen, it might snap itself in its position
yes i hadbsame problem....sometime it worjk and sometimes not.
(google translate):
not a few minutes, even the first problem, I thought the silvery on top of the screen display would be a film, it had settled a bit now, I have noticed that the touchpad is probably a way which responds to the stylus, it only reacts even if I pressures on the htc logo, otherwise, as indeed are among the contacts, how can I re-ordered or re-stick?
LCD-Screen is broken or its the motherboard (maybe it's that little strip which is connected to the LCD-screen and the motherboard or the LCD-Screen itself is broken), the digitizer is probably fine, if you've a warranty on your phone then send the phone to them and say that the phone stopped reacting on your taps (tell the story in a way that it wasn't your fault, so yes I request you to lie about the issue). If you've no warranty call your insurance and tell the story (again). If that didn't worked buy a OEM LCD-Screen and find a tutorial how to replace it (calling your insurance is the best one of all 3).
lcd replacement
yes yes... I did replace the LCD display, but nothing happened. It behaves in the same way as I wrote in the first post. Think the motherboard could be broken. I gave up on it. There was no warranty so I looked for another HTC but thx a lot to all here....
Please post in the correct forum, as your problem solved closed and moved.
Hi,
I have recently bough a Nook Simple Touch with Glowlight (BNRV350). Used, no guarantee. It looks fine (has only a minor scratch on the light dispersing layer). Problem is - the lower half of the touch sensors give misplaced readings. For example - during the registration process I cannot get through the language selection screen. I can correctly mark English, but when I want to press an arrow to go further, Nook changes my mark to French, instead of getting me to the next screen. Cleaning borders of the screen with microfiber cloth and cotton swabs did not help.
I have another NSTG working fine, so:
1. I tried to copy its stock system backup and loading it to malfunctioning one. It didn't help. I could not even unlock the screen (although I could press "power off" or "cancel" buttons after holding power button).
2. I tried swapping mainboards (IR sensors are on them, not in the screen assembly). And It turned out, that wherever mainboard of the faulty unit is, the touch does not work properly. I tried to blow out the dust from those misbehaving sensors hoping that it just somehow got on the motherboard, but it did not help either.
So the question is: What else can I do to make those IR sensors work properly?
Thanks in advance for looking into the problem!
(Sorry for my English, I'm used to reading, not to expressing my thoughts with it.)
Maybe try to look on the sensors with a cellphone camera in dark room-then probably you will see which of the ir leds aren't working (if the problem is in leds not the sensors)

Unfortunately I couldn't find any camera able (tried mobile phone, point'n'shoot, DSLR...) to detect IR in their stock configuration (and messing up with disassembling the sensor filters seemed as not worth the case). I ended up buying another NSTG with shattered eink screen and salvaging its properly working mainboard (+completely fine battery, all for about $7). Problem solved. Kind of.
If you are having problems with the touch screen try using the app posted here:
http://forum.xda-developers.com/showthread.php?p=52723066#post52723066
It may give you insight into where the problem is.
It will help us get an idea of where problems are occurring.
Thank You. I've read about Your program, but since I could not even unlock the screen or get past registration wizard (when trying to get that unit to factory state) I was unable to use it.
The Menu button (when you mapped) gets past the swipe.
You can start stuff with ADB intents.
Hello!
I recently purchased a broken S4 with a 'flickering screen' issue. Normally, people are told to return the phone for a replacement, but I can't do that.
In more detail, the problem begins after using the phone continuously for several minutes. The phone works flawlessly regardless of the broken glass screen, but after a while, begins to flicker. Only slightly at first, but then more and more severely until the screen shuts off. Turn the screen on and off again, and it's back to normal. (you normally need to leave the phone for a while before turning it back on, or it'll quickly just flicker itself off again). This to me suggests an over-heating problem, but I can't be sure.
I've wired the phone up the the TV using cheap cable, and the flicker doesn't show on the TV. That is, the phone starts going mental, doing its flicker thing, but the image on the screen remains constantly smooth when swiping - no flicker.
So... is this an image with the digitizer or the cable attaching the digitizer to the motherboard? If the screen doesn't flicker on the TV, that means we can rule out a motherboard issue, correct?
I just want to know what part of the phone to replace really. I don't want to buy a £80 digitizer only to have the same problems once it's been replaced.
Any suggestions welcome, cheers!
Based on your testing, it's very likely that you can rule out the motherboard. Unfortunately, that leaves the screen. You'll have to replace it, and you can reuse the existing midframe, but save as much of the adhesive as you can after peeling the old screen off, as the new screen doesn't come with adhesive to mount to the midframe.
Unless of course, the place you buy the screen from includes a small roll of the stuff.
Hello,
As @Strephon Alkhalikoi said it may depend on the motherboard.
Sometimes the kernel may be the cause too, I suggest to try first to reflash stock ROM. Here you can find how-to
With due respect to Antaresone I think I've found the best solution out there for most annoying screen flickering issues... Done a substential amount of digging and finally discovered the app "Twillight" works like a charm by enabling backlight control feature... Try it out first, then thank me and share your experience here ...
Hello,
Since a few days, the touch input of my front (LCD) screen stopped working. Nothing looks damaged, the screen still displays what it is supposed to, but there is no reaction to my inputs (actions on volume and power buttons do work, as well as on the e-ink screen). Did this happen to any of you? Any suggestion on possible ways to fix it?
I should also mention that it still works by moments, like half a day working, then 2 days not responding, etc. I tried shaking it in different ways should a connector be slightly displaced, with no success: the few times it started working again came like a (good) surprise. I also had the great idea to do a factory reset, so now the phone is stuck on the Android configuration wizard, which must be done on the front screen (no possibility to use YotaMirror, apparently).
Thanks!

i recommend reflash it. possibly and more strongly recommend to flash the same version and region which was installed for example HongKong 4.4.3 baseband number .HK1.0.36a

Actually, I forgot that the front screen was replaced several months ago (by a repairer that mistakenly changed the front screen instead of the e-ink one which was having an issue).
The factory reset didn't improve the situation, the front screen becoming "touch-insensitive" every few days. After checking how the screen connectors are supposed to be plugged (opposed to the screen), I noticed that gently tapping the phone front screen down helped to solve the issue each time it happened. A few days ago, I finally opened the phone (quite easy, there are two useful videos online) and unplugged/replugged the screen connector. It has been working fine since then.
If it happens to anybody (who would have its front screen replaced), I hope it can help!
