[Q] swapped motherboard now touch screen un responsive - G1 Q&A, Help & Troubleshooting

yes hello, big headaches here, bricked a g1 then got a hold of another g1 with cosmetic issues to use the motherboard, this new one was locked, so i unlocked it (using the trackball tho so i dont know if it also had a touchscreen issue to begin with)took the motherboard out of it and put it in my old g1 that i know for a fact had no touch screen issues, and now the touch screen is completely unresponsive in my original g1, so i took the mother board out again put it back in the one it came out of, and its touch screen is also completely unresponsive, my question is can the motherboard be the reason a touch screen isnt working? if so how and why?
also, the mother board i swapped works in my original g1, it has a signal, takes me to the touch the green android symbol to begin set up, also does this is the cosmetically challenged one i bought but neither one has any response to touch.
any help i would really appreciate.
thank you,
john.

Touch screen not responding after hard reset..hardware problem?

I have searched for solutions for the past 2 days but cant find one, if i missed it or this post is redundant , i apologize in advance.
Now my tilt is driving me crazy. It started last week when The touch screen wasnt working, but i fixed it by doing a couple of soft resets. then all the sudden, everytime i slide my keyboard out, the touch screen would stop responding. this went on for a day, then yesterday, when i tired to use the keyboard, the screen went blank, like the light died or something. but when i put it back on portrait, the screen would light up again.
A few moments later, the touch was responding, tried to use the keypad then the screen went blank..tried soft resets about 5 times and uninstalled all recent added programs (skyfire) ..finally the screen was working but the touch still wasnt working.
So this morning, i had the bright idea to do a hard reset....dumbest idea ever cos now its stuck at the screen where i have to "tap the screen to set up your wm device" and guess what..the touch screen isnt responding
plz i really need help with this. all so , i have a broken tilt.., well lcd screen is cracked...can i try to dismantle both tilts and replace the screens?
Ok, i used Code Factory's Remote screen alignment to bypass the alignment, but if i cant use the touch screen or the keyboard, the phone is pretty much useless for sending any information or making calls..is there a way to fix this?
I have had this same issue with my tilt. I could use the scroller on the left side of the unit to navigate but no touch screen. Both times that this has happened to me I removed the screen protector that I had on and restored a backup that I had on my storage card (I run a backup weekly). This has always fixed my issue. You could try another hard reset, not sure if that will help but do you get any lights on the keyboard when you slide it open? Is your tilt less than a year old because there is a manufacturer's warranty too.
Jim
when i slide the keyboard, i do get lights on the keyboard but not on the screen...it just goes dead..but when i slide it back in, the screen comes to life.
I cant do another hard reset cos i have to input the "1,2,3,4" code.
Also , the phone just got out of the 1yr warranty this month...awesome
I want to buy a replacement screen with a new digitizer but i need to be sure that is the problem.. ive searched for this keyboard problem but still have no answers
Now I'm having the same issue, touch not responding. I first noticed it about two days ago, when I slide the keyboard out, I could type just fine, but when I went to send the message the touch screen wouldnt work, so I'd close the keyboard and it would work. well yesterday it stopped working all together, so i used my d-pad and did a sprite restore and it started working again. But then On my way home i hit the lock button, and it stopped working after that, and I couldn't get it unlocked. I used the inner soft key to hit the first part of unlock, but then I couldnt ever figure which button to hit to get the on screen part of the unlock. So I had no choice but to do a hard reset, and just like highoct now I'm stuck on the stylus setup , and the touch still doesnt respond. does anybody esle have any suggestions ? Thanks in advance.
You can use the Code Factory's Remote screen alignment to bypass the alignment.
If the touch screen is the only problem, you can do one of two things if you are no longer under warranty;
1. Fix it yourself. You will have to buy a new Lcd screen with new digitizer at ebay and use this site http://www.pdacenter.ru/razborka/razbor_htc_kaiser/ to open up your tilt and replace it
2. Send it to a repair shop, I had two tilts and sent the one with the broken screen to www.missionrepair.com got it back in a within a week, $89.00 plus shipping

I still have the same tilt with the original problem..havent found a solution yet
Oh yeah, I did manage to do a hard reset again, but now the screen is just white. I can hear the sound of it booting up but it still has a white screen. I tired going to the Bootloader screen ( Camera and power at the same time)...still have the white screen. I believe its a hardware problem but i don't know what it is...any ideas?
Ok now I've done a hard flash, using the same HTC kaiser rom 6.1 and it fixes the problem for a little bit, until the first time I slide out the keyboard , then the screen stops working again, any suggestions ?
iPhone 3G Screen Repair...finally an affordable answer
If you are reading this, you are most likely in the same dilemma I was in. I dropped my phone and picked it up only to find out that the glass screen was cracked. I took my broken phone to apple and found out it would cost me $199. I then was told about iPhone 3G Screen Repair. They offered the iPhone 3G glass screen repair for only 69.99. They repaired my phone the same day they received it. I was very happy with the repair!

I know this thread is a bit old but was searching d forum for possible solutions cos yesterday i developed the same exact problem on my kaiser for no apparent reason!..flashing it hasnt helped and now im stuck on the wm setup screen..when u say u still have the same tilt with the original problem do you mean that the repair was unsuccessful? have you tried reparing it yourself? Thanks
I just started to have the same problem, it started out with the touch not responding (which a few soft resets fixed) and now the whole screen doesn't function unless i slid out the keyboard or if i jiggle it around and open it a couple of time i can usually find a spot that allows the screen to function with the keyboard closed. If i leave it in this position for about an hour the touch starts responding again, wtf. This is very inconvenient because as soon as you move the screen even just a little it will take me like half an hour to find the position which allows the phone to function.

same thing happened to me 3 days ago. touchscreen has just stopped responding.
it still worked when i slided my keyboard out, but only when it was out. then i realized it won't work at all (!) after soft reset. however, i could make it work again like that when i did the soft reset with the keyboard out. weird.
i tried searching, and decided to make a hard reset, flash a new rom, etc, etc., but no more touchscreen. at all. the device doesn't feel any touch in any case. nothing. i bypassed the beggining tap here with the storage card trick. (i've read it somewhere on the forum).
now i can only use my kaiser with the hw buttons, the keyboard, and that's it. no touch. really weird. please if anyone has any updates, solutions, anything, post. sniff sniff
mine doesn't have anything on the screen unless i slide it out, if i have it closed anymore, it just doesn't work at all.
try this:
ive just replaced my barely functioning lcd by myself, after living with it sometimes registered the stylus jumping around when i used the stylus. but before you change your lcd, here is a couple of tips for you guys:
1) try sliding out the keyboard. hold one finger in the middle of the keyboard and another on the back side of the phone, and squeeze hard, but careful. it might be that the flat cable between the screen part and the main part has loosened a bit from its socket, this could help it back in.
2) try sqeezing the hang up button hard. this might help the lcd-cable correctly back in its socket if it is loose.
im saying that this MIGHT help, if youre lucky. most likely you have to open the phone and squeeze the connectors back in yourself, or actually change the entire lcd. anyways, let me know what works for you!!

well, i tried both tips, but they didn't work. i'd like to say a big thanks anyway!
then i grabbed the kaiser service manual and took my device apart into pieces. i reconnected pretty much all the cables and stuff, but still no touchy. any further ideas?
you should try replacing the screen. im happy to say that this screen from this seller on eBay worked for me: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250539984183

touch screen not responding

Well ive had my phone for a while with hyperdragon iv iolite working completely fine without any hardware or software issues for months. Today i took out the battery of the phone, and put it back in and turned it on, but when the phone turned on, the touch scrren is not responding to anything. everything works fine with all the buttons and keyboard, but the touchscreen isnt working. What could have gone wrong just by taking out the battery. I also havnt dropped or damaged the phone in anyway so i dont see it being a hardware problem. Thanks. I really need help
I have heard of people who has been able to solve this problem by hard resetting the devise. I have had not such luck....comes to be that from sliding wear and tear the connector to the screen gets damaged. My screen is completely disable, I found someone that was able to buy a second hand phone on ebay and was able to switch the connector. Looks like to much of a hassle to me, so Im sticking with this until I switch phones.

ATT Tilt: Changed broken screen, now touch doesnt work

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.

[Q] Digitizer acting fuzzy

Hello, from some time, the digitizer of my g1 is acting weird, the bottom right part is not sensitive at all, and sometimes the screen gives to the os a completely wrong input, so the screen flicks by itself
Anyone knows what can cause this?
Thanks

well my G1's sensor act different whenever I connect it to (not compatible) charger (i.e. Blackberry's OR Motorola's)
Can't say it's due to fall of your G1 (my G1 fall a hundreds of time & still no problem but just accelerometer got screwed )
It possibly can be cause of you HARD PRESSED that part somehow somewhere .......
OR concern some repairer to get it fixed (i.e. Change digitizer)
Best of Luck

[Q] Repairing/assembling G1 -> broken volume rocker and touch panel

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
