by Robby-GrHi all,
I’m trying to recover a Samsung UE55HU8500L (curved UHD, 4K model from 2014) after replacing the panel. The new panel is a 55A1UU8EH, which produces excellent image quality — very close to the original.
However, since the swap, the TV enters a boot loop (Samsung logo → restart) unless I enter the service menu and perform a reset.
