Turns on but dead screen - myTouch 4G Q&A, Help & Troubleshooting

I had flashed a rom and then decided to go back to the rooted 2.2.1. After a while I started to have issues where the screen wouldn't come on from wake. After a battery pull and a reboot same thing. Then the screen would not come on at all. The phone boots and the hard buttons light up as well as the led. Anyone else have a similar situation? Is it bricked or is it possible to fix?

I have had the same problem although my screen works again when I pull the battery and restart. I am a little concerned If this has anything to do with the chip failures being discussed in the general forum.

Id get it replaced. Sounds defective.

It's bricked... get an RMA asap.

Unresponsive screen

I was fully rooted and then brought my evo back to factory stock. I don't have the newest update but now my screen has a life of it's own. I have to turn the screen off to regain the touch screen... Anyone else having this issue?

Graphics messed up

I was watching a video on youtube today (not sure its relevant) when I went to the home screen my whole screen began to flicker and all the items randomly shifted to different places continually. I shut down the phone turned it back on and even at the boot screen it was still continuing I continued to a restart and it fixed the screen back to normal. Has anyone else experienced this issue. Could it be the video chip for the phone going out or just a bug? I am running the latest version of themed iced glacier

Known issue, it's kernel's fault. Give it some time, it'll get fixed.
Thank you for the response

all backwards button

I was wondering if anyone else has ever experienced this issue. I am currently running the latest cyan 7 nightly but i do recall it happening 2 other times on cyan 7 RC4 and RC1. I am not at all saying it only happens on cyan, i am just showing when and how it happened. All 3 times it happened my battery was below 10% and i restarted my phone to have the issue occur. It seems as if every button on the screen would choose the exact mirrored opposite of itself on the screen. If i would press the phone icon on adw the default on the other side wich happens to be internet browser would launch. If i pulled down on the notification bar the app drawer would open and so on and so on. the only thing that was regular was when i would press an option in the main menu such as wifi or location, basically anything that didnt have an option next to it that it could switch to. after a few minutes i restarted the phone again to have the issue go away as fast as it started. It was not only in adw for those wondering it was anything that had an option next to it, such as pressing favorites in the browser and it would launch whatever is opp of it, settings i think im not positive at the moment. Oh well i just figured i would share some of my story with all of u in case it somehow starts a topic or even some how helps somebody out in any way. thanks, veritas

I work for a cell phone repair company and we recently had a G2 come in with heavy water damage. after doing the water damage treatment the phone powered on, everything working fine.
I powered it off to put my SIM into it to test the call functionality and when it powered back up the entire touchscreen was backwards, even the softkeys at the bottom.
we replaced the digitizer and that fixed the issue, so maybe T-Mobile or HTC will warranty it if its a bad digi

Led wont turn off

Hey guys obviously I'm having a problem that my green/red led doesn't shut off it just continues to stay on. I was wondering of there is a way I can turn off led notifications or disable the led all together? I'm running cm7.
Thanks in advance

And I don't mean just like turn it off through settings, because that does not work. Is there any way to actually turn it off through terminal or adb?

Dont mean to sound harsh - when did you get it wet?
That would make so much more sense but I haven't put it to test really with water. It just started happening out if nowhere
Sent from my HTC Glacier using XDA App
lol. Notice how I didn't ask you "IF" you got it wet, but "when"?
I see this all the time. All it takes is a drop of rain or steam from the shower.
You have the same problem with different roms? 99% of the time something like that is water damage or some other hardware issue.
Also, there's no way to do it with ADB.

MT4G Dead?

Phone vibrates 5 times and has a green LED light that stays on. I was running Dark Unicorn v2 before this. It was on Safe Mode. I rebooted into recovery, and now the phone vibrates 5 times and a green light appears. VOL DOWN + POWER does not do anything besides that green-light five-vibration thingy.
Any ideas?
From what I read before, it's not dead. It put itself on some kind of mode. I don't remember where I read about this but let me do a quick search. In the mean time, have you tried adb?

I've been reading a lot about it. There was something called safe mode. From what I've read, it seems to be a problem with my volume button (perhaps the phone believe the volume up button is being pressed).
I cannot use ADB as the computer does not detect the phone/SD.
Does your volume up button feel like it's going out? Also try a battery pull then Vol down + power

I'm not exactly sure what you mean by "going out", but from the outside there doesn't seem to be anything physically wrong with it. I also never had any problems with it while I was using the phone normally.
The battery pull and VOL DOWN + POWER gives me five vibrations, and then a permanent green LED. I can't get the phone exchanged because I'm in India, and my warranty has already expired.
Well sorry but I'm out of ideas man. I'll keep searching for an answer and if I find something I'll let you know. Hopefully someone else sees this and has a solution

Thank you for the information. Guess there's really nothing I can do to save my phone then...
Well, at least I will be out of the T-Mobile contract in February. Then I can get a new phone, and use a temporary crappy one until then.

This happened to me and I kept trying to boot into clockworkmod recovery. No matter what I did, it wanted to either do as you stated above or it would immediately try to load off the sd card my pd15img. I simply turned off the phone, pulled the sd card out, and when the phone went to the hboot screen with a volume up and power, or volume down, I then put the sd card back in and selected recovery. I don't know if this is what's wrong with yours, but I definitely had that 5 vibration flashing light issue.

If you can get to the hboot screen you should load the pd15img. It would hopefully start you over un rooted

What does the phone do when its plugged in? I only ask because mine was doing this same thing and it turns out it was a problem with my battery. I got a new one from Ebay for about 5 bucks but I also convinced T-Mobile that it was my phone and got it replaced. I had Insurance on it of course.

I had that happen once also, I did the following and it booted up.
1) take battery out for at least 15min, (I don't know why, but it worked)
2) then do the volume-down+ power it should come right back up.
3) If I remember right, the battery that was in the unit giving me problems, was less than 20%, that very well could have been the real issue. Find a way to charge the battery then pull it.

1 + 2 tried, but didn't work.
Maybe I will try it with a new battery. Thanks for the information guys!
Edit: I do not have insurance (1 year is done)
The PD15IMG I had on my card was the original stock Ginger bread I think and I would had to have re-rooted.

Problem is, my phone doesn't even go into recovery...or hboot.
Any solutions yet? I've been reading this and have done everything here.
I've bought myself a new replacement battery off eBay. Charged it over night and still nothing. Powering up the phone, it vibrates. After powering up the phone and left it on for 5 min, I waited to see if it'll recognize my phone through the computer so I can check if it's the phone or the lcd, but still nothing. Any suggestion will be really grateful! And I have no insurance. Bought it used over Craigslist.
Sorry, I'm not trying to jack anyone's thread. Just didn't want to start a new one with almost the same problem.
I think your volume button is stuck was reading somewhere that someone fixed it by taking his volume button apart and it was stuck pressing up I think and that's y it was doing that not sure if this would help u at all but you might wanna try that

Read that post it shows that the volume up button is stuck. The vibrations happens to me to if I power my phone down and then hold the up button and try and power on so I think that's the cause of all this
