What you'll notice
A burnt smell from the TV, scorch marks on the board, or a component that has visibly failed.
Why it happens
A component failure severe enough to overheat or char — often triggered by a surge, but sometimes a slow failure that finally let go.
How we fix it
We isolate the TV immediately, assess the extent of damage (board-only vs collateral damage to the mainboard), and give an honest repair-vs-replace call before any work proceeds.
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.
