Tv turns on then off two seconds later?
I have a Samsung UE49NU7100k TV that repeatedly turns on and off the moment it has power. I have tried a few trouble shooting solutions found here and have also changed bother the logic and power supply boards within the TV and still the problem persist.
I have found out that the tv will power on and stay on if I disconnect either one of the white ribbon cables as pictured, it does not matter which cable I disconnect, as long as one of them is disconnect it will stay on.
Does anyone have any ideas of what could be causing this as I’m starting to think this is a panel issue as I said above I have changed both the power supply board and logic board for known good ones…
Thanks in advance
