Broken screen need help - HD2 General

okay so my screen has broken, it is not cracked and i do not know what is wrong with it. When i do turn the phone on the backlight turns on but remains black and the actual screen does not when i do manage to unlock the phone even thou i can not see what i am doing i can still touch the touch screen to press buttons as i can feel the vibrating of pressing buttons.
What i really want to know is does anyone know what is wrong with the phone and why its doing this?
Thanks

My phone just developed this exact problem. At first the screen was offsetting the graphics half way up the screen, and hard resetting fixed the problem briefly. Now the screen stays black, but responds to touch and the backlight works.
Did you ever find out the cause, or a solution?
I have a tmous hd2, running a stock winmo and darkstone's new superRAM build.

I just found that a hard reset (hold vol. up + vol down and hit the reset button) fixes my problem.
Thanks xda wiki!

Well, today my screen failed again, in the same manner. Now a hard reset does not fix the problem. I am beginning to think it is a hardware issue. If I fix the problem or find another thread that addresses the issue I will post it here.

912c Power Button acting funny

Hi,
I am using iPad 912c. I love this machine but the little silver power button is acting funny sometimes. Normally, when I press the button the screen should be turned off immediately. But sometimes the screen still on for 4-5s after pressing the button. First I thought I didn't press the button properly. But if I press the button several times the machine can remember how many times I pressed and switch the screen on and off (sometimes ask me if I want to turn off) like having a ghost inside. Looks like it has a buffer for the power button. I don't think it is the software problem. Because I tried to soft reset the machine. The machine still remember how many times I pressed the button before reseting and turn on and off the screen several times after the machine back on. It happens twice a week. Is it a hardware or software problem? If it is hardware problem the iPad should not know I pressed the button several times. This is not a popular machine but I am sure it is one of the best. Please help. Thanks.
Anyone has the same problem? Please help

[Q] need help with my touch screen. tmous hd2

So recently i start flashing and using langthang's MIUI roms and keeping update and flashing all his new release rom. so couple day ago all of the sudden, i don' know what causes it and how it started it. my red button on far right. pressing it turn on and off the screen.so now when i press it to make the screen go back on from off mode. after i pressed the button the screen light turn on and the lock screen is there but when i touch the screen and try to move the ring(pyramid lockscreen) up to unlock, but the ring is not moving, it like there is no touch screen ability to my phone's screen.
but when i use the green button far left, the button usually to use phone. that button doesnt turn off the screen but it just turn on the screen, this button is working normally. i can move the ring up to enter the main screen.
the screen isnt cracked or any thing, but i do have a protection layer over it which been there since i got the phone and never got this problem before.
what do you guys think my problem is and how can i solve it?
thank you!

[Q] touchscreen stops working after pressing power button

since yesterday, i have this nasty problem with my touchscreen. when i press the power button to wake the phone, or to get into the power-menu, the touchscreen stops working. this does no happen if i press any other button.
sometimes, i can use the phone again if i wait until the screen turns off and then wake it up by pressing any other button, but most of the time i need to pull out the battery and restart the phone. even when i pull out the battery, the screen won't work sometimes, and i have to restart the phone again.
when i first experienced this problem, i was using the nexushd2 v2.0 rom, i then updated to the v2.1, which didn't help. i tried reinstalling the rom, wiping the /data/ , the cache and the dalvik cache (multiple times) and eventually changed to the typhoon cm7 rom (with repartitioning and reinstalling the magldr), the problem is still there.
the phone did never get wet, fall down, or anything the like. pulling out the sd card makes no difference.
i hope someone can help me there
May be it´s a hardware problem, some HD2 have it.
You can test it, if you go back to windows.
its the good old digitizer its right under the power button press the end button hard and it should work again but if you press it again it will corrupt use softkey or remap your hardware buttons

Lol, I was about to do that
@OP, in future please use the search button before posting. There are far too many threads in this forum with exactly the same issue as Kamerius has just proved, so why couldn't you save both us and yourself some time and search first? Anyway, what you have is a digitizer issue, but a quick temporary solution is to simply press as hard as you physically can on the end call/power button. The screen should work after that. Use a button remapper or some sort of widget to enable you to use the phone without ever touching the end call button, and make sure to use other buttons to wake the screen.

i have the same problem with the endkey but with the rom in my sig
it actually has a softkey button that can be setup with a power softkey ..longpress on the softkey and it pulls up the power menu
just like it would do if you used the hardware power button
Yeah I thought there were softkey power buttons but I wasn't sure and I'm on my phone so couldn't be arsed to search

well, sorry dunno why i didn't search the forum before
pressing the power button hard worked , but i think i'll keep using soft buttons and wake the device pressing any other button (i don't think the brute force method is a good idea as i want to keep my phone some time longer )

I am facing the same issue except no matter how hard I press the red button....LCD doesn't works. I have even replaced the thin metal strip which rests under hardware buttons.
Anyone?
Exactly, the same issue started to happen yesterday!!!

[Q] Touchscreen not working on lock and reset screens

In the last couple of weeks, when the pattern lock screen is displayed, it intermittently doesn't accept touch input. If I power off and on the screen quickly, it then accepts touch input fine.
Similarly, if I press and hold the power button (with the phone on), it brings up a "Phone Options" screen, with options for Silent, Airplane, Profile, Reboot and Power Off. Touch input does not work at all on this screen. I'm working around this by using the Quick Boot app.
Otherwise, touch input works fine, so I don't think it's a hardware problem.
I've seen something similar when Google Nav gets in front of the lock screen. Touch doesn't work until I power off and on the screen, and enter the lock pattern. Could something invisible be getting in front of the lock and power screens?
Using Pongster's HyperDroid-GBX-v12 (2.3.3).
Hey there,
Maybe the ROM h doesnt function properly on your device. Try shifting to another rom. All are equally amazing. If you do not want to shift, try running task29 and start the process all over again

Have you read the thread about the unresponsive touchscreen, where pressing hard on the end call button fixes the screen touch? I assume your problem is in essence the same; once you press it hard enough to actually unlock the screen the touch works fine.

That probably is what the problem is. Btw to everyone, I haven't noticed a difference in pressing it really hard, I noticed that pressing it a lot of times does the trick

Thanks for the feedback. I don't think it's the ROM, been using GBX-v12 since it was released, and previous versions before that.
The symptoms do seem similar to the other thread, but others report it on many screens. I only get it on the lock and reset/power screen. Otherwise, it works fine. However, those screen are brought up after pressing the power key ...
I suppose if it is hardware, then it's likely that cable issue. If it's software, then a reset should clear it, so I might try an ICS ROM from scratch first.

I guess i shoulda commented that how my digitizer began acting, it only did it while in the power menu but after a couple days it started doing it while just hitting the power button to put it to sleep, so i remapped my green phone key to be the power button

Thanks for the tip. You're right about the symptoms getting worse, it now occasionally stops working on other screen
I'm using any button but power to turn on the phone. To turn it off I've added "Go to sleep" to the notification widget bar, which I assume is the same as pressing power??
Not quite as user friendly and sometimes I forget not to use power off, but it'll do for now!

Yes that will work! I used it cause I got lazy and didn't feel like changing the key file but it's much easier to use the green call key instead of the notification power widget

Try this:
Lock the screen normally, screen turns off.
To turn it on again by pressing any other screen buttons other than the power button.
I found that if I do it this way, the screen runs normal.

[Solved] Nexus 7 Power Button

Hi all, I am having a very strange problem with the power button on my Nexus 7. The problem is that sometimes when I press the button the screen does not come on and I have to press it several times or I have to press it very hard to get the screen to come on. Pressing the power button to turn the screen off does not cause any problems though. The fact that the screen would turn off okay but not turn on made me think it was a software problem, but doing a factory reset or switching ROMs didn't help so maybe it is a hardware problem. It also happens in recovery mode (TWRP 2.6). I can turn the screen off and on rapidly with the power button with no problems, but once the screen is off for more than a few seconds it's hard to get it to come back on. I thought maybe it was sticking or something, but again I never have any problems turning the screen off. I bought the device used several months ago, but it was originally purchased over a year ago so I don't think warranty will cover it. I only noticed it start to do this in the past couple of weeks or so. Any suggestions on how to fix it? Here's what I tried:
1) Factory reset - No change after the factory reset
2) Flashing a different ROM. I was running stock rooted 4.3, also tried SmoothROM and cyanogenmod but get the same problems. Also have the same problem in recovery mode.
3) Opening the back case - didn't notice any physical problems with the button. Even when I press the little round metal button on the inside of the device that corresponds to the power button I get the same problem. It makes the normal clicking noise but nothing happens unless I press very hard.
Anyways, it's not the end of the world I just have to press the button very hard to get it to wake, but it is a bit annoying and would be nice to be able to fix it.
Update: Ok, this is strange, but I just did another factory reset and it seems to be better now. I'll keep you posted in case the problem returns.
Real strange!
