I have the same exact problem on my 55' Frame TV. were you able to solve? SO very frustrating.
Have you been able to solve this issue?
I have exaclty the same model and also the same issue.
It will cost me 150 or 300 euro (depending if panel or board is broken) to fix it by samsung service.
Any success on a solution? I have the exact same problem that started 2 weeks ago...
Hey all. So.. I took it down and into a local repair shop for Flat Panels and it looks the the Mother Board was no good. Costing roughly $385.00 USD to replace with Samsung parts which seems a tad high but less than a new Frame etc. I believe the One-Connect cord was also bad but I luckily had an extra so hoping this is solved. Good luck!!!
