Here is the problem:
I am able to turn on my Proscan LED TV, the power LED turns blue(meaning it is on) and an image of the Logo appears. Quickly after the screen goes black(about 1-2 seconds). I have not tried playing sound through it. I have put the screen in a dark room and have tried the flashlight test on it and I was able to see and navigate around the menu when the light was shined at a specific angle. I have done some research on what the problem could be and I believe that I need to replace the T-Con/LED Driver board. I believe this because the LED's illuminate for a second or two then turn off, so I dont believe there are any broken or burnt out LED on any of the strips. another thing that points to the driver board being the culprit is that the TV passed the flashlight test and was showing an image on the screen that wasnt illuminated/bright enough to see (meaning that the logic and power boards are operating correctly i think). what i am worried about is that the LED driver board is working correctly and causing the strips to shutdown as a safety because of a short or bad LED. Is there any way that I can be certain where the problem lies?
I also have a decent amount of tools and knowledge on electronics and circuit repair. if you need me to take voltage levels, i can.
