Black screen, no sound, stand by light flashing and LCD still works?
Hello all !!!
So I posted last year about my Samsung UN65eh6000fxza led LCD Television 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
Это хороший вопрос?
Would that be the T-CON board?
no, I believe your TV has the backlight circuitry on the power board
Ok, I took off the back of the TV and saw no visible signs that the boards were bad . I do not have a multimeter but I am getting one tonight. I also took some pictures but can't get them to load will try again after work
Mine is the bottom half
