Black Screen No Picture No Sound No Standby Light Samsung Television
Chosen Solution Hi, I have a Samsung TV UN40MU6300FXZA that stopped working. When I unplug the wire harness between the power supply and main board, the backlights turn on. So I thought it would be the main board, so I replaced it. The tv still did not work and I still have NO standby light. I get voltage at the power supply but thought maybe I am missing something so I replaced power supply too since it wasn’t expensive....
