Television Won T Turn On When Plugged In Makes A Buzzing Noise Samsung Television

Chosen Solution

I went on vacation and when I came back my plasma TV wouldn’t turn on. It makes a buzzing noise when plugged in. I took the back off and checked all the components. Nothing appeared damaged. I replaced the power supply board. The TV still would not turn on and the buzzing noise remained. The only time the buzzing stops is when I unplug the cable that connects the power supply board to the main board or when I unplug the TV entirely. There is no standby light, and I’ve checked the actual power cord. Any other suggestions?

this isite the are I’m talking about. It may not be this at all. But once I unplug the cord connecting it to the power supply board, the buzzing stops. And as you can see there is another smaller orange and black cord running directly to the tvs power buttons. I was gonna order another main, but wanted some advice.

Kandace Clarke  since you already replaced the power board and the buzzing comes from the main board, I would proceed with replacing it. There is no visible damage on your board
