Hey guys, i was wondering if anyone could possibly..suggest what my problem could be .. and what replacement part i should get.. ok my tilt's lcd screen is non responsive .. it only responds if i hold down on the left soft key..then im able to use the touchscreen.. so im wondering is it the digitizer that needs replacing ? the lcd screen ? the lcd main flex cable ? i have touchflo installed..but i dont think its a software issue..because windows align screen..doesnt work..(only if i hold down the left soft key) so im guessing its definately a hardware replacement part..?

Hello, I am a true noob so please forgive me if I sound dumb.
I had a broken screen so I bought a new one on Ebay. I changed it perfectly, it looks good but now when I touch the screen it acts like I touched the top left corner (in portrait)no matter where on the screen I touch (so it opens up the "Start" menu). In landscape it acts like I touched the top right so it opens up the drop down menu with all the running programs.
I would really appreciate some help. I try re-aligning the touch screen but it does not recognize any touches at all. I have to soft reset the phone to get out of the re-align program.
I don't want to hard reset because I have read many cases where the phone gets stuck in align program as it is trying to setup and they have to install remote access or something to get around it.
I would like advise on whether it is the new screen or the phone. Is there something I can check for inside or should I send the screen back for a replacement.
Thank you for your help.
Having replaced the touch screen in a Palm with success, I would say that...
You either have a problem with the connector for the screen, recheck the connection
Someone sold you a bad screen.
Something else is wrong with the device.
At this point I don't know that in your position I wouldn't do a hard reset. What is the worst thing that can happen? The device is already broken in it's current state.
Good luck.
Thank you
Thank you very much for your help. I will try the connector. if it does not look damaged then I will return the screen.
Did you replace just the screen itself, or the screen and the digitizer? More than likely your digitizer is broken aswell. If you replaced them as a set, request a new one from wherever you got it, and if you just replaced the LCD, then you need to buy a digitizer aswell.

Well, I only received the screen. I cant figure out where the digitizer is on the tilt so I don't know if I changed it or not. Does any body have any picture??
I think I read somewhere that it all comes as one piece(the screen and digitizer), but I can't confirm it.
Indeed they most of the time do come as one peice, so if your connection is good on the mobo, then I would say that the digitizer you recieved is bad. The digitzier is the super thin peice of glass that covers the LCD screen.
I dropped my HD2 and now i have a broken screen...but i can still see the wallpaper behind the broken screen and can use the hard button to receive calls.
Only thing that is not working is the Touch screen.
Now i dont know what to get...Should i first get the LCD screen and try to see if it'll solve all the problems...or should i get the digitizer? Or both?
Thanks
If the LCD is not broken then you need a digitizer. But the two are bonded together quite strongly, I am sure someone will tell you what to do for the best.
If you do get a new digitizer then you should make sure you get a T-Mobile one, the HTC ones have a different connector..
Hi
I broke my touch screen and change it with new form ebay.
Until i do this, i am not sure, but i think i broke main flex cable here:

Up and down buttons doesn't work, is there possible to affect touch screen?

no , the volume has different cables , most of the time you physically cant push in the volume buttons if you assemble it the wrong way
Hi,
On my MDA compact IV I have te recalibrate my screen often.
When I have calibrated the screen, it can be I have to recalibate it after 2 or 3 houres. If I dont calibrate it again I get problems, for example if I touch on a send button on the screen It tries to call someone because the call button is below the send button...even sometimes it doesnt even respond at all....
In this topic: http://forum.xda-developers.com/showthread.php?t=1001105 I saw there is a reg edit possible for the calibration of the screen, but its for another phone (touch HD). Does anyone know if there's a regedit for the mda compact to solve this weird problem? Or do I need to replace some parts of the phone?
Greetings.
Hi,
This also happened to me. I had to recalibrate it more and more often until the touchscreen died completely. I've bought the touchscreen and LCD together on ebay are replaced the screen. Beware - do not buy digitizer only, the digitizer and lcd are glued together, and one can not remove touch screen without breaking LCD.
Cheers

Well, I fixed my old broken G1 with new screen, touchscreen panel, case and keyboard.
Now I have 2 issue:
1) Sometimes my touchscreen goes grazy!! If I use the touch test application I see that sometimes when I touch the screen in an area there is another virtual touch in another zone of the screen. I read that it can depend from the current source when I charge the phone.. but I'm going crazy!! I opened my phone 10 times (I thought there was a problem in the cable that link TouchPanel to LCDPanel, because when I lock the cable with the clip it tends anyway to go out from the connector, now I put some scotch tape to fix but the problem is here.. so I think is another problem).
2) My volume rocker doesn't work!!
I bought 2 new keyboard to fix this problem, but no one of that fixed the problem. I thought the first new keyboard had volume keys broken, so I bought another one, but the problem persists!!
Now the Touch problem rarely happens, but the volume rocker is completely unusable..
Someone have experience about G1 assembling/repairing ?
Thanks and sorry for bad english
if you have put in multiple keypads have the same issue i would assume that it is the connection going to the motherboard. just a guess there but its either that or you have had a bunch of faulty keyboards.
only other thing would be a software problem
does the keypad work in recovery (let you go up down throughout the list) ?
as for the touch screen, probably need a new digitizer or flex cable, both are cheap and it sounds like you have the knowhow to replace them.
Ok, but digitizer is new!! screen also is new, and I have bought a total of 4 flex cable because I see that they are fragile (I broke the first I bought).
I tried to change flex cable but the problem remain the same.
The only thing that can be damaged is the LCD cable that links to the flex cable: it has a small cut where the cable have a curve, but the cut don't reaches the contacts (the cable is transparent). I also use some glue and scotch tape to mantein lock the cable.
The digitizer cable is connected to the LCD cable, and then they go to the flex cable that connect them to the motherboard.
The strange thing is that seems a software issue, because if I turn off and than turn on the screen, the problem is fixed for some seconds, minutes and sometimes hours...
Another strange thing is the possibility to control the screen with some metal objects from the moment that the virtual touch problem appear (I can control the screen also without touch it, with hand and piece of metal)
video:
have you tried a factory reset if you think it may be a software issue? if that dosent work you can try install a whole new rom.
really it sounds like it isnt the hardware since you appear to know what youre doing. i have a had a few phones that had screen (digitizer) issues and a new rom flashed cured it just fine
since you dont mind putting a few dollars into it, and your familiar with the inside, you can always try to pick up a cheap motherboard or spare phone from ebay or what have you, then swap the motherboard and you could then hopefully find out if it is the hardware or software

Huh sounds like you got a cheap digitizer than. Most good digitizers use heat to touch. If it's literally touch, then sounds like its a fake/meh digitizer. i hate the digitizers that aren't heat, but press. I see them all the time in those first samsuck touchscreen phones. And they usually die in a bit. I had a Samsung behold with a screwed up digitizer

Yes I flashed 3 or 4 roms after a wipe (I tried also super-wipe.zip), but the problem is here..
The digitizer works well some times, but sometimes get crazy (you can see in the video).
I don't that my new digitizer is fake, but I really don't know!
BTW I'm trying to repair my phone for fun (now I have desire z) and because I am fascinated by my old G1.
PS:
I see another strange issue--
If I touch the screen when the phone is on a table the screen digitizer is not very sensitive and can't take input from fingertips.
If I touch the screen when the phone is in my other hand, the screen digitizer is a lot more sensitive and it take input from fingertips.
My impression is that there is an electric field or something similar that disturbs the digitizer, and when I take the phone in my hand I discharge that field to ground. Also when I turn off the screen, seems that the electric field discharge so when I turn on the screen is ok, but after some seconds the field returns to disturbs the screen.
I really don't know, but is the impression that I have.. something that is not shielded.
Now I'll try to use my phone in airplain mode.
Thanks guys, I'm happy to see that this forum is still very active
