What you'll notice
The TV works, then freezes or reboots itself with no pattern — sometimes during a specific app, sometimes at random.
Why it happens
Overheating on the mainboard, a marginal power rail feeding it, or corrupted smart-platform software.
How we fix it
We check power delivery to the board first (a power-board fault often masquerades as a mainboard fault), then address ventilation, firmware or the board itself as the evidence points.
Still not working?
If the checks above haven't restored your mainboard (logic board), this usually needs a technician. Our TV Mainboard Repair service covers exactly this fault.
