Hi,
I've tried a number of firmwares Europe/Asian/T-Mobile and my local Telstra Rom. But no success.
I replaced my smashed digitizer and LCD the other day, however everything works great, the touch response is inverted - Left to Right. All touches on the left side are responding as if I'm touching the right side of the screen. Everything in the middle is fine obviously but from there it's mirrored.
It's quite possible that because the digitizer was bought from the USA and its in a Telstra (T8697) phone, it's somehow incompatible.
By bootloader is stating the TOUCH is C1(v66)
Does anyone think they may have a solution to this? a Registry edit or some kind of Screen calibration?
Cheers for any help.
BTW - The digitizer capacitive buttons are also mirrored i.e. Back is Search and Search is Back.
This digitizer also has a circle around the Windows (Start) button. My old screen didn't have this..
same problem
Hi gauge41,
I have the same problem :crying:. Do you have a solution ?
I bought my touchscreen on uk by ebay.
Reference:
cgi.ebay.fr/NEW-DIGITIZER-TOUCH-SCREEN-LENS-FOR-HTC-7-MOZART-T8698?item=270791784120&cmd=ViewItem&_trksid=p5197.m7&_trkparms=algo%3DLVI%26itu%3DUCI%26otn%3D5%26po%3DLVI%26ps%3D63%26clkid%3D5080495740069852992
All updates have been done through Zune software without changes.
Best regards.

I've read somewhere, that there are two modifications of a touchscreen for mozart and they are not compatible, so if your previous digitizer didn't have a circle around windows button, but new one does, mirrored input is definitely because of that. Haven't heard of any registry tweaks to fix that, and I don't think you can fix it by installing different rom. You should probably get a compatible digitizer replacement or try installing different touch screen drivers.

I flashed a newer rom onto the phone and since, my touchscreen does not work. I have searched and seen posts that this is a "hardware" issue but since problem occured during the flashing process, I'm hoping it can be fixed.
I have seen something similar in posts about the wifi eeprom being erased. Can something like this have happened to the touchscreen controller?
So far, I have flashed various radios and various OS builds both stock and custom and it is still a no go. I can get past the alignment screen by remotely connecting to the phone and taking out some registry keys (can't remember which right now).
Using Pocket controller I can control the screen except for the screen alignment calibration which wants a pen tap.
Does anyone have any ideas other than "send it in for repair?"
adding...
Just thought I'd add that this was a second machine that I received as payment for helping out a friend. And, while I would have no problem paying to have it repaired or breaking it down to sell as parts, this issue of dying touchscreens gnaws at me as being something fixable through software.
That said, I am not a programmer so maybe I'm just simply wrong. It's an interesting problem though. Makes me wish I knew more about electronics...
I might be way off, but....check the system information for the operating system version, WM 5/6 Professional Is Touch Screen, WM 5/6 Std is not.
Thanks
Thanks for the suggestion but I'm sure the rom I flashed is a touchscreen version.
Well for what it's worth, if anyone is in the same boat, the registry key to delete will be at HKLM\Software\Microsoft\Shell\Rai\:MSWelcome
delete the entire sub key as well as the value in :MSWelecome that has welcome.exe in it.
hold the power button until the popup comes and then answer yes. when the machine reboots, it should bypass welcome and the screen calibration.
you can get Mobile Registry Editor here:

this will let you access your phone's registry from the PC. Good Luck
I wouldn't think that it's the flashing process that broke ur touchscreen. Probably something else like a power surge or something. If you already tried flashing different ROMs, then it's definetely not software anymore. But of course, I could be wrong. There may be some low-level programming thingy that crapped up the connection to the touch screen.
Yeah. You're right. I was hoping that if it was a low level thing it could be fixed with software but I guess not. It was worth a shot.

Why dont you try running a very thin visiting card or anything equally thin between the housing and the screen,sometimes if a tiny partical gets lodged inbetween this problem may occur.
Touch Screen Problem
It is a hardware issue, i have had the same problem. There is no software that is going to help you mate. I restored my original t-mobile Rom sent it for repair and they exchanged the unit. Don't forget they have a manufactures warranty.
I tried everything to try to resolve the problem but with no sucess.
good luck
Update
I've narrowed the problem down to the actual touch screen. I can get the touchscreen to function correctly if I put just enough force where the mylar flex cable attaches to the touchpanel.
It is a very odd coincidence that the touchpanel died just as I was flashing from WM5 to WM6. I distinctly remember doing the pen calibration just before flashing so that I could see the screen for any prompts.
I've ordered a new touch panel and now the next challenge will be figuring out how to bond the flex cable of the touch panel to the main flex cable.
Anyone got any ideas on that?
Hey guys,
My screen woes just won't go away. I dropped my phone a few weeks back and cracked the screen. Ordered a new one from eBay (Item number: 260818538062) with the faceplate and everything. Had it installed but then started noticing that SWYPE wasn't working as well because my words would start breaking midway. Installed Yet Another Multi Touch Test and when trying to paint realized that there is a very evident line on my screen that isn't working as well. That was one continuous movement of slow up and down jestures but as you can see, the touch sensitivity is much weaker as well as the screen sensing a second touch at some point.
What can I do? I will gladly take the thing apart and clean the connectors.. if that will help. But somehow am inclined to believe that the issue lies with the screen. Is there a software recalibration fix that exists perhaps? Anyone experienced the same thing and walked away with a working solution?
Please help and thank you in advance.
(EDIT) I've added a second attachment where I started going around the outer edges working my way in, there's definitely one faulty line in my screen!
(EDIT2) Found a native Android touchscreen test (white and green) thanks to a member named BryanNL in a different post. Basically had to dial *#0*# and chose it from a menu. This test claimed that I passed but you can see that it is not made to tackle an issue like mine.
Bumping.. Anyone please.
I read a ton of threads regarding this very common problem, however I was hoping I could find information more specific to my problem.
I bought the Atrix and it had Nottachtrix. A few of the keys weren't working in portrait mode, and in landscape they all work except the word correction bar. I flashed it back to stock, no difference. I recently flashed Neutrino GT, and still no difference (although the ROM itself has improved the phone IMMENSELY). I used a calibration app, seemed to help a little bit when drawing, however the problem keys in portrait mode (U and N), and correction bar in landscape persist.
I noticed that this phone has def. been taken apart, seems to be a small smudge on the LCD and the screws have wear. I assume he replaced the digitizer.
My question is..Can I try the PDS partition fix running the Neutrino ROM, or would this cause issues? OR, does it sound like I should just replace the digitizer? There seems to be a lot of different digitizers for the Atrix on eBay, I worry I might pick the wrong one. Could I open it up and attempt to "fix" the digitizer?

Its not a PDS problem... you should change the digitalizer or send it to repair.
Aroma Installer With Nowatrix
I dont know about that soto.. Funny coincidence same thing happened to me after running Nowatrix with the aroma installer. my keys are different, letters SZE dont work. Theres a straight line from bottom of screen to top which doesnt react to touch input. Heres the thing though, going back to the aroma installer that "dead zone" line can be moved by calibrating the touch input.. Seems to me what happened on my end was i chose alternate input and then saved the settings.. I know it's only supposed to use the settings within Aroma, but after that my phone has had this "ghost line". Screen worked just fine before using Aroma with Nowatrix.. For a cheap fix i "moved the dead zone as close to the edge of the screen as possible, and use the landscape keyboard at 270 degrees.. Tried the two fixes here on xda, neither worked, but i think the original mmcblk0p3 which btw is in my /dev/block/platform/tegra-sdhci.3 folder , is being rewritten on reboot. Grrr Im so mad, I had just got this tempermental phone running like a charm too.. So just for the record TheFullSpectrum, you can use the calibration gui within the aroma installer to maybe move that dead spot elswhere on your screen to make navigation or selections easier on the touchscreen. or like i said the "rotate phone 270 degree" trick untill someone can think of something to fix this... I wouldnt replace that digitizer just yet Spectrum, or bother opening it.. Aroma did it to me, theres no doubt about that.. Just need to find out now if the damage is as simple as misentered location information from the Aroma calibration gui, that can be reentered or changed back to proper dimensions, or if the calibration technique has actually damaged the screen.. God I hope not the latter.....
I was faced with the same dilemma. I tried the PDS fix and it didn't do anything for me, but I felt as it was free for me to do, it was worth a try. I eventually bought a new digitizer on eBay for ~$45. I have only a few weeks left until I'm eligible for an upgrade on my AT&T plan so I get to sell my phone and get a new one. My advice to you is that if you're anywhere near your upgrade, sell your phone on eBay (as is) and get a new one. You won't make your money back if you install a working digitizer.
Also, I've read that digitizers can go bad at any time. There seems to be an inconsistency in the design process.
Just my 2 cents
EDIT: I was successful on fixing mine but the one I bought didn't come with any type of adhesive or anything so I had to superglue it to the plastic frame. I ended up getting some on the screen and I had to clean it off with acetone. The screen has these ugly stains/marks now that are impossible to remove. It sucks because I was extremely careful during the whole process and I still screwed up. If you end up doing yours, do it in a dust-free environment and be really careful!
Hello Guys
A question to those people who disassembled their LG P500
I Have recently replaced entire housing to a new one, including touchscreen digitizer(went from red body to white).
Everything went fine, however i did not aligned sensor rubber correctly and had to disassemble phone again. After correct alignment and final assembly, discovered that touchscreen does not work anymore...
Phone is working fine, but no touches registered.
Any ways to check correct contact between touchscreen and motheboard ?
tried several times, but no luck
any useful notes are welcomed
Thanks

Already tried to replace like 3 different touchscreen digitizers - no luck - so i'm sure it is not digitizer malfunction....
Take it to service

hi there
I've got some strange issue with my lcd screen on my atrix. Everything is on this video(sorry for quality):
http://www.youtube.com/watch?v=bbMsmbblXLc
I don't know what to do- i don't have my warranty because of unlocked bootloader(in Poland they are very strict and surely they won't fix this on warranty.
So the issue is: when i touch near front camera/ front speaker the virtual finger appears. The second thing is that when i touch in showed area
there are 2 touches from one finger. It isn't a rom issue because it is on all roms i've tested.
If you have any idea what should i do please write it
Thanks in advance for any help
I'd say your digitizer is dying. Except unlike most others where a part of the digitizer stops registering touches, yours registers multiple touches. Either way, I believe buying and installing a new digitizer would fix this problem.
After a night which phone spent in home there is no additional touch in this line. Of course the issue with touching near camera didin't disappear.
Maybe it is because of very low temperatures in Poland nowadays and i think there can be some water inside of phone. But as you said
i'll think about changing digitizer
