Maybe just your phone is fully freeze after boot. Do a full backup, and install an other ROM, for example CM7.

Supupa could be right...the phone isn't frozen as animations and text messages still shows and the problem persist with a fresh cm7 flash also..

if you're under warranty ask for a replacement. you should get one back at no cost since there should be no signs of damage
if not. i replaced my digitizer a couple of mouths ago, its no to hard. i did post a thread in the general section which did have a few videos about replacing it. good luck

Try flashing another ROM? I don't think it's a hardware issue if the buttons light up when you touch the screen.

G1 Unresponsive - Requesting Help

My friends G1 is unresponsive whenever the screen is closed, but seems to work when sliding it open. The funny thing is, while the device doesn't perform any actions when the screen is closed, it still seems to be responding to touch. When the screen is opened again, your touched actions will "catch up" and the phone responds. This happens from recovery mode as well as in Android.
Can anyone help?
Anyone? Please?

The phone is in standby/sleep mode while screen is off, so you cant use the touch screen. You must double tap Menu to get to the home screen.While in recovery mode you cant use the touch screen cause you have to use the hardware buttons or the trackball. Im guessing you were unaware that the phone goes into sleep mode. When you slide the KB the phone wakes from sleep mode and allows you to use it.You only have to slide it when you need it not just to do it randomly.
No no, sorry if I worded it incorrectly. The screen is on and it is frozen when the slider is closed. Once you open the keyboard, everything works fine. As soon as you slide it in, the screen freezes on its current display and stops updating.

What rom are you using?
If it is a hero rom then it doesnt work while in landscape mode so you cant open the KB while on home.
Its a 2.1 ROM by Kingx
The screen behaves the same in and out of android though...such as in the recovery (JFv1.4) console. If the screen is closed, the screen "freezes", but the frozen picture is still displayed. If you slide the screen ouţand expose the keyboard, it works fine. The phone otherwise operates normally, as does the standby mode.

You need to upgrade your recovery though

Try wiping and reinstall the rom and wipe everything.Also you need a task manager cause you might have a billion apps open.
I'll try it on his phone when I get off work. Thanks for the recovery link. Do you prefer this over JF?

JF is super old and lacks many features from Amon_Ra. But it's based off of Cyan 1.4 recovery. It makes a lot of things easier like partitioning,wiping,backup,restoring roms.
Alright,
Home now with his phone. I swapped JF's recovery with RA. The issue still exists, and I'm wondering if it's hardware related...
This is frustrating. I don't know if I can fix it for him...
The problem seems to have gotten worse on its own. If the screen is closed at all, the screen will go black with a slight image shown with what seems to be an unworking backlight. However, upon sliding the keyboard open again, the backlight does not return until the device is rebooted while leaving the keyboard open.
Edit:
The backlight seems to come on sometimes when you slide the screen open...

You might wanna wipe and install another rom to see if the problem stays.There might be a hardware problem with your phone.
I've wiped and tried a couple of other ROMs but the issue persists. If it's a hardware issue, is there anything I can try to fix it?

It could be the ribbon that connects to the display.If you can find the assembly guide you could replace the broken or loose piece.But i'm not 100% on which part of the display needs to be replaced.You could ask someone at T-Mobile or at a electronics store what the problem is.HTC offers a free 2yr warranty so you might be able to get a replacement.
Bumping this to see if this was ever resolved. Having the same issue, and considering replacing it brand new, but wanted to know what exactly needs to be replaced so I can order it.

Dead Touch Screen??

Hello,
My Touch screen doesn't respond to touching since an hour ago.
I see no logical reason for this fault,
My screen is guarded and nothing happend to it.
I tried to remove battery and insert it with no luck, I booted my phone into CWM touch recovery, and it also doesn't recognize touching.
update2:
The problem appeared again.
just flash a kdz to return to stock rom

The problem appeared again I tried a lot of times to remove battery&insert but it doesn't help.
Please help me.
I've just flashed my phone to stock rom,
I'm still having the same touchscreen issues - the screen won't respond to touching.
Any suggestion please?
Is it possible that the touchscreen issue is caused because of the screen protector?

Screen protector protects screen If you have got stock FW back on the phone, just bring it to your carrier and they should do it on warranty.

Thanks for the advice,
I flashed stock rom and now when I turn on my phone It shows me the "Android Welcome Screen", Is there a method how to bypass this screen without touching the screen? (If I'm taking phone to my carrier, it might seem strange to them that my phone shows the "Welcome screen" whether the touchscreen doesn't work so they could know I flash my phone and not to accept my phone's warranty)

You can try on-screen phone, which is a software by LG, but i think, that this also needs to be setup first... Otherwise, just tell them, that you did a factory reset, because your phone wasnt working properly anymore, and thats when your error occured.
I dont see another way... Maybe repair it on your own

I'm going to take my phone back to carrier
But there's very strange thing: the touchscreen rarely works.
I removed the battery for a night and when I got up in the morning and I inserted the battery and turned the device on, for a few seconds the touch worked . What does it tell about phone?
I've just received my phone from repairing, and my touch screen has been replaced.
I'm a little disappointed because I expected for getting new phone(I have a warranty). I've also noticed that the screen is a little thicker, about few mm, which is weird.
Is it right that phone with replacement touch screen won't be as smooth and good as normal one, or not necessarily?
Same problem of Freezing screen
Disappointing but i too have this very same problem with my brother's P970... any ideas how or why?
though sometimes it would respond but leaving it a few minutes would again make it freeze. The hardware buttons work but the 4 touch buttons wont. now i cannot get thru the rom manager to make it into Bootloader mode so i can install another rom...
some things i did a few days before this happened:
1. flashed CWM recovery successfully.
2. installed a lot of apps and happened to fill up the SD card.
3. installed a new ROM Gingerbread Repackaged V20N
I can still get to S/W Upgrade but all I need is the Bootloader Mode. I honestly dont think this would be a digitizer malfunction since it works well in a given time. It's like it lagggggs much and unresponsive. I cannot get past the lock screen. Any ideas or any other way to get to the B/L mode? Thanks.

ARZAKEM i have the very same problem too i was also doing the same stuff which you atempted and end up with none responsive touchscreen.
my phone is since then lives in a my draft in the kitchen and i was also curious about the malfunctionality because it worked sometimes and other times not.
I just thumbled upon the post when i search the web i know its too late to ask but could you please please tell me what you done with that phone ???
I ordered a new touchscreen from ebay and it will arrive soon but i was wondering wether you managed to fix it or not? could you please tell me what was the real problem did you replace the touchscreen or is it not the touchscreen?

You need to indicate your current ROM. Then can the issue be accessed

Strange problems

My phone LCD backlight went out but other than that worked fine. After installing a new screen the phone will not boot past the moto logo.
I can get into recovery and charge only but if I try to boot normally it goes blank after the moto logo not even showing the boot animation.
Reinstalling old LCD allows it to boot but with no backlight is unusable.
Anyone have any ideas?

Assuming you are 100% sure you've hooked everything up correctly, it sounds to me like a faulty/incorrect screen. I've read about this happening to other people (Bionics, though), luckily (so far) I've never had any issue with any screen replacements.
I'll check the connections again. The replacement screen came from a damaged Droid 4 that would not even show the moto logo.
I was lazy and rather than open it all the way and replace only the screen I swopped the whole upper part of the phone slide. I'll try doing it the right way.
Edit: checked all connections and tried again. Still no go.
Where is my torx 3 bit!
Edit 2: tried again. Still works with old screen switching only the screen (and the things that CAN NOT be separated from it) still won't boot. looks like I need a new screen.
Did you buy a broken D4 and try to swap the screen? If so, that unfortunately might be why it was broken in the first place... The plus is that might then be an easy fix too... Then you'd have two!

I did get a broken D4. It had a bad board and would not even show the moto logo.
What's really strange is yesterday it was still not working and today it booted fine but now the touch screen is not working.
I'll keep trying to fix it.
Honestly it sounds to me like the front portion is busted. Perhaps it is just the digitizer that is broken, those tend to be much cheaper than LCDs...
Good luck and let us know how it pans out, it is always good to hear solutions to hardware problems!
Both touch screens/digitizers work with the lcd that has a bad backlight but not the one with the good backlight.
I examined the LCD with the good backlight and found a very small tear in the ribbon. Looks like I found the problem.

Same problem here! BUT It only appears on Customroms. Nothing similar in LG ROMs. Even Miui-Gingerbread didnt had that but CM.
So I guess its not an hardware issue.
I had this too...and it only occurs when i'm using custom rom too...the only solution is to turn off the screen and turn it on again

Mee, too, Had this when using custom kernel wel almost stock ics rom. Some flashes futher (now on PA with Kowalski ) the problem has disappeared, so there is a software component in this bug.....

[Q] Screen randomly stops working?

Hi there,
did anyone else have this problem? Occasionally, my screen would not react to my touch input. That is either the status bar stopping in the middle of the screen whilst collapsing, a character on the touch keyboard appears pressed and activated, even though I don't type anything (Can't continue writing when this happens) or the widgets screen on the home screen appears and re-appears and I can't change the homescreens since they are stuck in-between.
This is my second Z (Switched from a black to a white one) and so far, everything's been fine. It doesn't have any custom stuff on it except root. But the problem also occured prior to rooting.
Does anyone have a fix for this? My workarounds so far: Switching it off by POWER+VOLUP or leaving it in standby for a couple of minutes.
Might this be a hardware problem?
Thanks you very much in advance!

you can try to reflash a stock ftf via flashtool, doing a full wipe maybe will resolve this issue!
