Phone Freeze > White Screen > Vibrate + Black Screen

[CallMeMTK]

My HTC was working fine yesterday until it froze at one point and it wouldn't respond to any buttons including the lock button (which has never happened before except occasionally during incoming calls). I did a battery pull and at first it would only vibrate and remain a black screen, though I could see that it did light dimly when I pressed the power button. After about 20 battery pull attempts it went back to showing the splash and screen and the phone turned on succesfully. After about 10 minutes it froze again, I did a battery pull and now it only showed the splash screen and froze, occasionally showing a red light in the top left corner. My phone was already on low battery so this process went on for another 25 minutes or so (vibrate + screen, freezing on splash screen, or booting then freezing) until I gave up. I came home and charged it overnight while it was off, and it was fully charged this morning, but now it won't turn on at all, it only vibrates once with the screen lighting very dim for a moment then just has a black screen.

I've been searching for a solution for the last 3 hours, seems it could be a range of things but nothing I've tried has worked. I'd appreciate the help, I already spent ?90 on getting the screen repaired a couple weeks ago, I don't really want to spend more especially if for some reason HTC decide it can't be repaired under warranty.

i read a thread about the htc black screen but couldnt write a reply for some reason. i just wanted to add my solution. the same thing happened to my phone. it was a black screen but only the four keys at the bottom were lit. so i went ahead and replaced the LCD screen it's not the touch screen on top but the one under it and now it works .
