Samsung tv UE50AU8000: screen turns on black and goes off repeatedly
Hi everyone
Somebody threw away this TV and I had to pick it up
As I plugged it to the socket the screen turns on black, and after a few seconds turns off in loops.
After watching a few videos I tried a few things with no success:
- Disconnecting the big semi white cable from the main board -the result is the screen turns on constantly on black, and there is a start sound. Then nothing happens, the screen stays on black.
- If I cover half of the cable with a tape, connect it and turn the screen on I get the same result.
- I tried using the "tape method" on the right side of the screen couple of times while slightly changing its location. Sometimes I got restarts in loops, and sometimes the start sound with black screen. Unfortunately no picture.
- During the screen is on, I disconnected the cable connecting the power board (brown) to the main board (green)- the result is the screen's backlight stays on.
What can cause the problem, and how do I solve it?
I'm a biologist, so please be gentle with me 😊
Update (03/24/24)
I looked on the ribbon cable, and found out its model SFPCX495G-005 (see attached photo).
When I was looking for a replacement online, I found the exact model, yet the latter 5 digits are not the same.
Is it important?
Should I look for the exact numbers on the replacement cable?

Have you tried a new ribbon cable? Or even found one for sale as in the same boat as you and after a good day of researching online and taking the back panel off and having a play 😅 believe it to be that which is at fault.
Please let me know the outcome as would really like to have a tv again.
