Black screen of death

The other day, I hit the power button on my touch pro, and the screen didn't come on. I did a soft reset, and it started working again. Now today, the same thing is happening, but a soft reset isn't helping.
The screen's back light comes on, the LEDs on the buttons come on, and the phone seems to be working fine. I hear all the sounds, including the HTC sound while it is booting, and the new message sound, but the screen stays black. It still recognizes touches, it just doesn't show an image. I want to do a hard reset, and will if I can get it to come one one more time, but its been about a month since I backed up my contact list. Lesson learnt there. I'm afraid it might be a hardware problem since I don't see anything while its booting either.
Anyone know if this is a known hardware issue with the touch pro? The phone is less then 3 months old, and I've been real careful with it. I haven't dropped it from more then 2 feet, and even that was onto carpet. Its the Verizon version if that makes a difference, and I'm running one of the NFSFAN roms. Its not the newest one, but rather the one posted on October 19th. I doubt its the rom, though, as I've been using it for around 2 months with no issues.
EDIT: Ok, I went into the bootloader to see if it was hardware of software. I figured if it was hardware, the screen would be black, and if it was software, it would be the rainbow. Sure enough, the screen stayed black. Hit the reset button, and the screen actually came on! Go figure. Went to do a backup, and the screen literally crapped out on me while I was watching it. Definitely a hardware problem.

similar with Touch HD... kinda
I've been having a similar problem with my Touch HD. The problem is very intermittent though and is sometimes hard to reproduce. The screen and phone will be working fine then once in a while when I push the power button to lock the phone, I'll unlock it and the screen stays black. I know that the phone is still on and even unlocked because pushing the buttons at the bottom makes the phone vibrate. The only consistency in reproducing the problem happens after I do something major on the phone such as making a phone call, browsing the internet, sometimes charging the phone. Other than that, I can sit here and push the power button all day and it'll come on and off with no problems. When the screen does go black I've taken the battery out repeatedly as well as repeatedly rebooted the phone until it comes back on. I've tried doing hard and soft resets to no avail. I've tried deactivating "turn off backlight if device is not used for" and "turn off device if not used for" without any resolve. After this I've even left the screen on (disabled backlight off) to see if it flickers or shows any sign of being faulty and it seems to be fine. I'm currently on Dutty's HD WM 6.5 Leo R5 WWE rom, but this has happened with two other roms (NRG, LIA). Other info include:
OS: 5.2.23016
Manila: 2.519192828.0
Radio: 1.14.25.24
Protocol: 52.64.25.34H
I guess the only consistent software has been my radio. Please help! Any advice would be awesome. I've tried google search and xda search without much help. Thanks

Buttons constantly and randomly pushed down, help!

Hey,
So after having browbeating my phone for 1½ years (and recently started bragging about it) something major has finally happened. Shouldn't have jinxed it.
Basically, it pushes buttons in random order. The things that happen (and can start to happen all the time, even before I enter my PIN):
Volume going up
Volume going down
Connection manager opens
Camera turns on
Switches between modes while in camera (panorama, burst etc)
I'm unable to try out if I can access connection manager and camera through volume up/down, but if that's possible then I'd say it's a problem with the volume up and down buttons on the side.
Also: I've lost all connection what so ever with my operator.
I recently flashed to Energy Phoenix 2.0 feb 26th build - Sense 2.1 21892 and it worked as normal for 1½ week. Then today I received a text, and then I lost signal and all the button mashing started happening.
It drains 50% of the battery in about 2hrs, leaving me think that it's doing something even with screen off laying on my desk.
Just now I flashed to Energy Leo feb 26th build, 21892 Sense 2.5 version and it's still all weird.
Anyone know what's going on?
UPDATE: argh, clicked the wrong button and lots of text disappeared
anyway. shortly: the buttons stopped working altogether for a short while, and it stopped ****ing around. Then they started working again and the ****ing around resumed. At one point I couldn't navigate away from the volume screen because of horrendously fast changes in volume. I've tried hard-resetting, but it wants to start up the camera the moment i'm done calibrating my pen resulting in canceled "first-time-installations-scheduled-after-hard-resets", with angry red letters.
stoopid phone

I Had the same problema, but worse, i have the same problem with the keys but also now the led of the flash of camera still on
So the ligh is always on, also when the device is off, i dont know what to do because im in mexico and no many people know abaut repair this phone.
I hope anyone can help thankss

[UGG!] Back button is driving me insane!

My back button is freaking out. It randomly presses and it sucks. I can't do much of anything on my phone because of it. Started happening last night and has lasted all through the day doing the same thing. Open an app and use it for a few seconds then it hammers the back button. (Or long presses it.) Doesn't matter which app, and sometimes no app, just the main screen.
Why is this happening? It had been working great. When I was on 2.3.2 it happened a couple of times and then quit. Now it won't stop. I've cleaned the screen several times. Wash my hands like crazy. Reboot, pulled battery...

happened to me after i restored apps with mybackup. i don't know if it was a specific app or something to do with mybackup. couldnt be bothered finding which app it was, so just factory reset to fix it.

I've seen that thread and tried to tighten screws but none were loose. I hoped to not reset...

The model working at The best buy store here has this issue bad. The back button simple doesn't work unless pressed extremely hard, enough to almost break the phone. The other 3 buttons work just fine though.

My back button is also less sensitive than the other buttons.
I can even use the phone with gloves, only the back button doesn't work.

I found one thread that said to turn off animation. I did but it didn't stop. It did seem to slow it down. Now it seems to have stopped for today.

i had this issue with my home button. it's a hardware issue not caused by any apps you've downloaded. you're going to have to call samsung and have them fix yours unfortunately. they won't send out a new one they require you to send yours in for repair and for them to ship it back out to you =/

my 1st ns had problem with back button with my second ns back button works great

[Q] Back button keeps blinking(and vibrating)

So my Nexus S 4g been mighty stable, til this morning. i check my bank account on my phone then all the sudden, the back button starts blinking like crazy, and everything goes back if i open anything, and the vibrate feedback can be felt like rapid fire. So I hold the button so I can actually power off the phone into recovery.
Its still blinking, so I hold it down so it sends only one signal, so i can change my kernel back from Netarchy 1.3.7 to 1.3.6 where it still does it. Repeat to Mathkids. I also wiped the cache partition, and dalvik cache for this one. havent tried stock yet.
Anyone ever have this problem. Its still doing it. Thinking about going to stock and returning phone.
And if I do return it, do I have to unroot, and relock the bootloader?

tried stock kernel, did a few backups, formatted everything agian, turned back to stock and it hasnt stopped.
did notice tho if my hand or thumb got close to the back button, but didnt touch it, it would stop blinking. maybe it needs a heat sensative calibration? it wont stop flickering no matter what

It seems to be related to this issue: www.google.com/support/forum/p/Google+Mobile/thread?tid=49e8ca84071d51a4&hl=en
Im having exactly the same problem, but with the searh button. In the Google thread a Google employee has replied, and according to him they're working on a fix (software related). This was posted a couple of weeks ago, i bet the fix is issued in 2.3.5, set to rls in the upcoming days.
For me the search button flickering seems to be related to how long the screen has been on, i.e. how warm it is. I can use it perfectly for 20-30min, but then its unusable for the next five. I discovered the relationship between screen on time and the flickering like a day ago and it may be incorrect. The Google employee says it is a software issue, but i dont hold my hopes high.

I was having this problem with the search button.
I goofed up something on the phone and ended up reflashing it back to stock like 5-6 times in the course of a night.
Ever since then, I havent had the issue pop up even once.
I also have read that it has to do with the NFC contacts on the battery cover. Someone was able to supposedly fix this by preventing the contacts from touching their corresponding contacts on the phone.

Galaxy s6 soft keys flashing

Hi guys,
My girlfriend has a galaxy s6 running marshmallow. The soft keys are constantly flashing/blinking whenever the screen is turned on. This also causes the device to lag, draining the battery.
I've tried factory resetting the device, and running it in safe mode suggesting it's not software related.
I also installed the the app "Galaxy button lights" that allows the control of the lights, this does stop them flashing, but the device still seems to be running slowly.
Thanks for any advice in advance.

Hi did you find a solution to this as I am having the same problem. Power mode on stops the constant flashing but the phone still lags and it flashes when I charge my phone. My power button also phantom presses :/

I have the same problem. Did you find a solution?

Me too. Turning off the buttons seems to help... it drives me less crazy... but it still feels like there is screen lag. I think this started after I installed the last system update.

One of my co-workers suggested that it may be caused by moisture inside the phone. I set it in the sun for a while, and the problem seems to have gone away.

This happened to me like 4 months ago, it hasn't "dried" till now However if i press hard on the lower left bezel - next to the app switcher button my phone works. I have a theory that the contact has become loose under the phone or so?

Hi, I have the same problem for a long time I installed a couple of firmware and the same thing on the factory software always happens, now I use custom rom and it works without problems, it means only on the factory versions I have a problem
