What you'll notice
No standby light, no sound, no picture — the TV is completely unresponsive to the remote or the power button.
Why it happens
A failed power supply board, blown fuse, or failed capacitors preventing the board from starting up at all.
How we fix it
We test the board with the TV isolated, identify the failed stage, and repair or replace the power board — then confirm a clean startup under load before we call it done.
Still not working?
If the checks above haven't restored your power supply board, this usually needs a technician. Our TV Power Board Repair service covers exactly this fault.
