How to troubleshoot no power on my Samsung PS51D6900DS Plasma TV?
- SStacy AlexanderAug 6, 2025
If your Samsung Plasma TV has no power, start by checking the internal cable connections inside the unit, as the cables might be improperly connected, or the Main Board or SMPS might not be functioning. Also, check the fuses of each part and the output voltages of the SMPS. If those steps don't resolve the issue, the Main Board might need replacement.
