Black screen, no sound, stand by light flashing and LCD still works?
Hello all !!!
So I posted last year about my tv and got side tracked with work. Since I'm hardly home to enjoy it and my wife said she didn't notice the problem anymore I let it slip. But it's gotten worse ( kinda what happens when you pretend nothing's wrong and ignore the problem till it can't be ignored anymore). So let's get started. A few months after purchasing this tv at Walmart for a great steal since it was a display. The top part of the screen became dim. TV was sold as is so no warranty. Samsung said to try updating firmware but I never could get the %#*@ thin to read the thumb drive, so we have old firmware still. A year went by and one day my wife says the tv wouldn't cut on. So I started the process. This tv has the power button built into the IR sensor. Turn the tv on and it flashes 5 times. The screen is black, no sound that I could tell and the LCD panel is still working. When I shine a light into the front I can see the white and black static from the tv input. I took the back off to inspect the boards. The main board BN96-28963A
looked ok except the back had some sort of gunk on it. Ribbon cables seem to be fine. The power supply led board BN44-00670A
has signs of heat damage on the front
of the board. None of the components seem damaged. No bulging or leaking. The T-Con board BN96-28894A
looks to be undamaged. But I'm just somebody who likes taking things apart and this is my first T-Con so I would trust that. I need a better multimeter before I can verify the voltages are right. I also have not tested the leds yet as I was hopping maybe someone could tell me if the problem could just be in one of the 3 boards. Thanks
Is this a good question?
