    Le40c750r2k video glitches and TV restarts after board replacement

    Hi guys,

    Me again with the troublesome Samsung LE46C750R2K I picked up from the street. So I installed everything into the TV tonight and held my breath as I plugged the system into the T-Con. I breathed a sigh of relieve when the display show a picture and didn't blow up on me. It ran for a little bit before it started it glitch out on me. Occasionally the speakers will buzz a little, picture will have artefacts and sometimes the picture would freeze together with the sound before the TV tries to reboot itself. At times it fails to reboot and I have to physically pull the plug to cut power. However most times, TV would work for hours on end without problem.

    I made videos of this happening. The picture froze, the TV tried to unsuccessfully restart before I physically cut the power and had to repeat a few times before it restarted but still glitch out

    Any idea about this problem? I hate to think that I'm supplied a faulty main board. How likely is this to be a software issue or indeed a connector issue? I'm using existing interconnect cables which lived through a faulty power board that took out the main board. I don't see any burn marks on any of the ribbon cables but I cannot see the inside the tiny holes on the connector for the wire between the power and main board.

    Same tv right, you don't need a new thread for same tv, just use the other one, 2 threads on one tv is confusing and pretty much a no no here.
