Touch Screen has a "Void/Dead" zone - MDA, XDA, 1010 Software Upgrading

My XDA I has developed a spot on the lower left hand imput area, where it's almost a dead zone. TO get accept taps, I have to press down harder than I'd like to, and the recognizer isn't terribly accurate in that area anymore ( i.e., I have to write in a small space for it to be recognized ).
The rest of the screen is fine. Is there somewhere I can purchase a replacement screen that I can put in myself ? Can the touch sensitive area be replaced by itself, and the screen left intact ?
Any help would be GREATLY appreciated. Thanks.

They sell replacement screens, touchpads, batteries etc. They come with instructions on how to do it, and there are other posts about this on xda-dev.

Is this the forum for repair advice? Digitiser recalibration

I dropped my phone and the screen now doesnt respond properly: The hardware DID successfully upgrade to the XDA ROM. But touching it causes the backlight to go on, - but most of the keys dont do what one would expect them to do: The phone turns on with a reminder from the calendar on the screen which wont DISMISS or CLOSE. Pressing on the windows logo and then on the phone key causes the calendar to come up and I am not sure which numbers are entered when I do manage to get the phone to come onto the screen (none of the right hand numbers seem to work at all). Does anyone recognise these symptoms and/or could they just show that my SX-56 needs the ROM RE-flashing? I should add that pressing the Master Reset button with this ROM in place seems to make the phone shut off and then when you restart it, all of the data remains in place. I wonder if there is any possibility that the XDA ROM has prevented the reset button from working normally?
A user on another forum said that to him, '"Sounds like the digitiser is up the swanee - have you tried recalibrating it?"
10-12 vertical black lines started appearing to the right hand edge of the screen. Sometimes they are there, sometimes not. THere is usually at last one there somewhere. At about that time the screen stopped responding as I mention. Today the left third started displaying the same veritcal lines, though spaced quite far apart (about a millimetre). Screen doesn't APPEAR cracked: Does this sound like a digitiser and if so, how do you recalibrate it please or is there a link to somewhere on the XDA site which I cant find which might tell me? Or could it be the cable is loose in the circuit board? As you touch the lower right hand corner of the metal casing where the vertical lines are, those lines flash (the right 10 or 12) on and off. And every coloured bar everywhere on the screen or word of text has vertical lines on it (the white parts don't)??
Someone on ebay has said that his phone "fell from my pocket and onto the carpet and the screen cracked, I then used it for about a week" "I sold the screen to someone cause the wanted the touch pad part of the screen for there phone". and wonder what it was he sold or which part can be replaced on it? IS there a touch part and a screen part on this phone?
To be honest, itsounds like you have brocken a connection somewhere between the LCD and the gfx output, probably not possible to repair yourself.
I wonder where the break would be?
I thought that might be the case: I wonder if it would be worthwhile trying to get another screen?
I should probably try to take the unit apart and see if some break somewhere can be identified if it is a break as opposed to some electonic part having failed. It SEEMS to be in the lower right hand corner?

Just sent off a "faulty" Touch HD.

Hi,
I think I may have made a mistake, but was wondering if anyone else has / has not had a similar experience.
I got my Touch HD a couple of weeks ago, and although I was completely knocked out with its amazingness ( new word, patented by me! ), something bothered me about the amount of pressure I was having to use, particularly in the centre of the screen when touching.
I know there have been tweaks and hacks posted and the pressure required on the touchscreen is variable, so I fiddled and tweaked and carried on. It was only after I started using FingerKeyboard2 (which also warrants "amazingness" status.) that I noticed that when holding keys down and releasing for special characters and numbers, my HD was registering a second press upon release. So when holding for number "5" I got a letter "t" too when I released. This really annoyed me.
I've had a look from a varry shallow angle at the screen, with the device turned off and pressed in the middle and compared to the edges, and it seems as though the digitizer "domes" over the screen. There's a large void in the middle that's not present at the edges, which means that to register touches in the middle, I have to press the digitizer against the screen. I think this is causing the double presses, and having to apply extra pressure in the middle.
Anyway, to cut a long story short, I've taken it to CPW today and they've sent off for a replacement, which will arrive on Monday
Has anyone else noticed this, is it normal and I've sent a perfectly good Touch HD away? Have a look for me please, and spare an old(ish) man his sanity!
I can only speak for myself but, specially after tweaking, the hd screen is VERY sensible to touch, no need for hard presses at all. I think you actually had a faulty machine...
My touch screen is very good, shame the wifi has died on it and it's doing strange things. Mine will be back to CPW as well
My touchscreen works very well, without tweaking I think it does the job and recognizes my presses easily and accurately. However, my problem is that I can see the touch sensors even when the screen is turned on... I see small green-coloured dots, in a regular grid, specially when I have a white background. Annoying, but I think I can live with it... Better than send it to the service and wait a long time, with the risk of getting a new screen which may have dead pixels (I don't have any now).
Thanks for your replies everyone, makes me feel better about not having my Touch HD over the weekend. I pick up my replacement tomorrow and I think I'm suffering from withdrawal already.

[Q] Digitizer Problem - Aria

Hi,
I just want to thank everyone on this site for the plethora of information that is available.
Here is a rather strange issue, that I did not see covered previously...
I purchased a used aria with a cracked digitizer off ebay for pretty cheap. I replaced the digitizer myself and all was good. I used the phone for about a week and dropped it. After that, the digitizer has been acting a bit flaky.
For instance, when it decides that it wants to annoy me, every input seems to register only on the middle of the screen. For instance, if I touch the top of the screen, the screen registers touches as though I was touching the screen in middle of the height. If I touch the bottom, it still registers the touch in the center of the screen.
I found that If I knock the phone against a table, along the edge, the problem goes away for a while. Then it crops up, again, randomly.
Anyone have this issue?
Thanks,
JC

HTC Raider/Vivid/Velocity Digitizer

Hi guys - got a question re: potentially restoring full function to a glitchy digitizer panel I bought as a replacement for my original (broken) one. I know this isn't a Q&A forum but anyone in here is likely going to have more knowledge of the digitizer from a hardware aspect than anyone in the general Q&A forums..I hope.
I had no trouble installing the panel, physically - the design was identical to the original and I took care when shaping the ribbon cable so as not to damage it. My problem is this: My digitizer seems to "skip" one contact point on both the x and y axis so that there is a dead area on my panel which makes text input quite a hassle. I can get it to read input from the area if I touch VERY gently and very accurately, but other than that it takes input from the sensors around the actual point I'm touching, like its getting more capacitive feedback from those areas than from where I'm actually touching.
I hope thats not too confusing. Basically there's a nonresponsive vertical line down the right side of my screen 1" from the edge, and another one 1" up from the bottom going horizontally. At the point where these lines intersect I have a hell of a time getting it to recognize where I'm touching accurately. I've tried the HTC screen calibration tool to no avail.
I'm wondering if anyone has any tricks I can try to get this sucker working properly.. Its slowly driving me crazy. I saw one guy on youtube take a much larger digitizer from another device and take a lighter to the glass side for a few seconds, then apply pressure to the heated areas on both sides of the glass, sandwiching it together and (I assume) reattaching or more firmly attaching the plastic film to the inside of the glass. I don't want to try this without first asking if its wise here, and see what more experienced people have to say on the subject. I may be way off here and there's a simple fix, I just haven't been able to find one.
Help!? LOL..*someone* in here must have some experience with this, no??
Thanks in advance for any replies. Helpful or otherwise.

Part of display nonresponsive to touch

I've had my Nexus 4 for a couple years I believe now, and overall it's been a nice device. I've had occasional issues now and then with software (Camera not available message, random powerdowns) but no hardware issues. A couple weeks ago, part of my display stopped responding. The LCD itself shows everything, there's no bars, no visible cracks in the screen. but the left hand side of the screen, I'd estimate about 1/5 the screen in width, no longer responded to touch. The far far left edge, along the very edge of the display, registered, and on the other side of that 1/5 worked fine. The area that was giving me issues was right about where the 'a' key on the keyboard is in portrait mode -- the only location I could press to get an 'a' registered an 's' as well.
This is all being tested with the developers Show Screen Touches and Show Pointer Information turned on.
Then, the end of this past week, it got worse. The entire left half of the display still shows fine, but almost never responds to touches -- maybe 1 in 100 times it will. Thankfully, I was able to get in one of those times and disable my screen lock. It seems to be able to register as far left as an x value ~418. This means the back button in portrait mode, for example, no longer works. To make me even more confused, it seems to register phantom presses. The device can be lying, powered on on my desk, no touching it, and the display starts showing screen touches -- the most common one I see is right about where the word Google is in portrait on the stock main screen. These will continue indefinitely.
All this to say, I suspect my digitizer has had a mechanical failure. Does that seem a reasonable conclusion to you? I like the four inch form factor of the device, and with most new smartphones getting larger and larger, I'm shying away from changing to another device. I've looked briefly at replacing the digitizer -- it seems you can purchase either the digitizer alone or with the LCD, and that when replacing just the digitizer it's easy to accidentally create problems with the existing LCD. Is that true?
Also, the part about having to use a hair dryer to pull the components apart makes me a little nervous. Screws and cables I can handle, but a hair dryer?

I would say it's most likely a hardware problem with the digitizer. The lcd/digitizer assembly is glued together so it's very difficult to separate the two without damaging the lcd.
Unless you have the tools to separate them properly, it's alot less headache to get the entire assembly already glued together.
