New LCD poor responsiveness - G2 Q&A, Help & Troubleshooting

Hi guys
I bought G2 with broken screen, replaced that with new screen - everything was fine. I did upgraded rom to higher version, after that screen become very difficult to operate. I had to press it very hard to make it work, and obviously no swipe option.
I disconnected all pieces and put together and there was no changes, however I realised that when I push back of the motherboard with force sometimes screen become responsive as normal, it works couple of seconds and become difficult again.
I have tried to localise the exact place when is a problem but it's like a lottery, sometimes it works in left corner, sometimes I have to twist motherboard a little bit.
I have read about motherboard problems on G2, but in this case it stopped to work after rom upgrade and it sometimes works fine so there is a chance to fix it I presume.
Any ideas folks?

At&t 8525 touchscreen problems, please help

Hello,
I've recently been looking around online to figure out a solution to my problem and I came across this forum, I honestly had no clue of all of the things possible with this phone...
I have an At&t 8525 (in august I will have had it for a year) and just yesterday I started having problems with the touchscreen, when I would try to use the touchscreen nothing would be functional...after messing around on the screen I found out that the lower right hand corner of the screen (the right hand corner when the keyboard is in use) pulls up the start menu...although the touchscreen didn't work the phone itself still did, I could access the start menu and other actions on the phone by pushing the soft keys...
This morning I started toying with my phone again and it worked normally for some time and then eventually the screen started to do the same as it was doing before...so thinking that the problem was a virus or something, I figured I would reinstall wm6 back onto the phone hoping that it'd restore everything to normal...now I'm stuck on the 'welcome to windows mobile green screen' and only once have I gotten to the 'align screen'...
I truly don't know what or how to fix this problem with my touchscreen and I'm really new to all of these phone experiences...(I'm pretty sure returning the phone is out of the question)
So any help given would be very much apriciated,
-Ben

This is a loose connection between the main .. device and the touch screen . There is this cable that connects the screen and the keypad .. that has a loose contact. press the screen and the keypad together and the touch sreen should start working again . i had this same issue i don't know how to fix it.
Sounds like this problem here:

The above is an old thread. You can try the old business card trick (though it's by no means guaranteed to work). You could try a dis-assembly and reconstruction, double checking connections - particularly the screen to d-pad connection.
The Hermes unlike the Kaiser is very prone to this kind of problem and despite the threads you may see, guaranteeing a fix, I don't believe there is one fix for this problem. This is because there are several variables that can cause the problem and it just depends whether your case is caused by:
Dust trapped under the bezel
A loose connector - possibly d/pad to screen
A failed capacitor on d/pad or main board
Another failed component
Digitizer coming unglued from LCD
etc

Had the same problem right before EVERYTHING went white. Replaced the lcd altogether, about $110Aud on ebay, and everthing works great again.

"Half-bricked" trinity after lcd broke - bootloader still working

Hello,
I'm facing the following situation:
I droped my Trinity and the LCD broke on the left side pretty bad. It booted fine after that (the LCD was still visible on the right side) but after 10-15 seconds it just froze. The hardware buttons were not working, nor the touch commands. I could only rest the phone with the stylus.
I successfully replaced the LCD by myself and now I'm stuck with the freeze. I was hoping the freeze will disappear but I have the same symptoms as before.
I tried a hard-reset but after that the phone froze during the booting process with the logo on the screen.
I entered the bootloader and connected the phone to the PC. It worked just fine and the freeze didn't occur anymore. I uploaded a new ROM but again, during the booting process I got the goddamn freeze.
I was hoping that everything beside the LCD survived the crash but I'm starting to have second thoughts.
I would appreciate any advice or hints on how to find what could cause my problem.
Thanks
If its freezing up on you then I would imagine you've caused some hardware damage.
Like you, I would have hoped that replacing the broken LCD woudl fix it, but there's nothing to say you havent partially damaged or dislodged something else, especially if it was a high-impact drop...
PS
I wouldnt try doing any more uploads to it either if I were you. If it freezes up during one of those then you could end up trashing the program area of your device too!...
Hi guys,
I had quite the same problem, without braking the lcd but anyway it fellt from a airplane onboarding bridge :-( and then it has started to randomly freeze.
I think I may have found something. I've noticed that when I press strongly the battery it's not freezing anymore!
I've opened the phone and saw that under the little metalic protection's plate there were a contact plate between a little black component and this metallic protection'splate. I've cleaned it, apply some thermal past (like cooling artic) and the I've put a little sheet of paper between the plastic frame and the metallic protection's plate. I've all remounted.. And surprise!!! not one freeze since two day!!
I hope it will last.. but if yes this s F### great
ähm.. I release any kind of responsabilities concerning this action. I'm not a professional but as soon as it has work for me I wanted to share it ;-)
Seeeervus!!
Dodjob.

Touch screen not responding

Well i think my Polaris has finally given me the finger.
The touch screen no longer responds to finger/stylus presses. If i press randomly for long enough it does register a click, but never in the right spot or consistently.
What do you think it could be?
Ive tried reloading different roms that have worked perfectly before, hard resets, and ive even tried taking it apart and reconnecting the connectors.
It was dropped a few days ago but it was fine, then one day, while doing nothing in particular it decided to stop responding to touch input, the normal buttons work fine.
My XDA Orbit2 (same as Cruise) has the same problemccasional freezing and touch screen decalibration (needs to be recalibrated every 5 min). problem is that this occurs infrequently. therefore i have lost hope that sending in for repair would work.....
i have a same problem..
my polaris's touch screen sometimes not responding to any touch.
i have to connect it to my computer or battery charger, and then it will work again.
can anybody explain to me why??
thanx before
same happened to me last week! well, its on its way to o2 service partner right now... guess it was supposed to brake in about 7months from now.

Hi!
I broke my touchscreen (Tytn2) and replaced it with a touchscreen from ebay for 10 €.
It works, but there are some problems:
1. I have to press very strong onto the screen for a signal!
2. On the edges i have to press very very strong - even stronger then in the middle.
3. the signal itself is on the right position......
4. i have already tried to reset the sensitivity of the touchscreen (and increase/decrease it)
5. i have already aligned the screen several times....
My questions are:
1. is it installed well?? (I had to connect 4 pins on my own.....)
2. if it gets the right signal (but only when I´m pressing very strong), can there be anything wrong with the connectors?
PLEASE HELP ME!
greetings!
Well i was SO close to just giving up and buying a new phone.
I found however, an entire brand new housing for the low low price of $65 AUS. I could of just bought the digitizer for about $30.
When i look at the devices out there...they arent that great...i was going to get a Nokia E72 but realised i would miss the touch input.
So i will suffer along with my touch cruise, checking these forums for updates on the Android progress
ANd ill have a spiffy new case to boot.
My 02 Orbit 2 touch screen has stopped working also - I found that a temporary solution is to hold the top of the screen tightly over the earpiece
It would register touches, enough to Flash back to Original ROM
It Going back to 02 this weekend.

[Q] Wandering screen alignment??

Hi all,
My trusty blackstone has begin letting me down and I don't know if flashing a new rom will help, or if it is something physical that is breaking / broken. I'm using the Stonehenge ROM with CHT and everything has been fine for months.
Recently the touch screen allignment just seems to 'wander' sometimes just a little, other times quite a lot (so much that using the fake hardware buttons at the bottom of the phone, brings up the start menu). This means that intermittently I cannot answer calls, and typing a message on the SIP is an absolute nightmare!
The start menu icons do not seem to be as affected as the home screen and CHT, and I can quite easily get to the phone settings and recalibrate the screen - this will help for a short while but the alignment drifts again.
Restarting the phone has a temporary positive effect but it doesn't last.
Anyone else experienced this?
I have exactly the same problem.
Dissembled the whole device, blown some hot air but didn't help. Seems it's a HW fault. But I have a doubt whether the problem is in digitizer or in control board.
It's definitely one of the more frustrating problems that I've ever had with the phone.
I might try flash a new ROM then give up if that doesn't work. At least I won't be tempted to disassemble as it has already been tried, tbh I'd have just tried the tin of compressed air too, I don't trust my soldering skills for tiny electronics.
It is getting progressively worse, the touch area of the screen has slipped so low now that I can't use half the screen.

Unresponsive Touchscreen

Anyone having touch screen only issues? There's not a single crack on screen, I've always treated the phone very well.
I'm thinking whether I should replace the whole front, but curiously only my touch screen is not working, display is OK and works well using SideSync. Also, the entire touch screen starts working at random times (I haven't been able to figure out the conditions, it's not hot/cold or pressure; I've used a hair dryer, a refrigerator and heavy items on top of it).
In fact, it worked for a month after it started malfunctioning (initially it didn't work for some hours, and then worked again). But now it got worse again. It's not software as I've tried XtreStoLite and now I'm back to stock. Should I replace the whole thing?
Oh, I have the G900H.
Sounds like a bad digitizer. It would be wise to shop for a new one before it goes out completely.
