What you'll notice
No picture at all, but the TV powers on, the menu sounds play, and streaming apps make sound as normal.
Why it happens
A fully failed backlight strip, blown backlight driver, or a failed inverter feeding the backlight.
How we fix it
We confirm the panel itself is healthy with a torch test, then replace the failed backlight strip(s) or driver board — a genuinely common and cost-effective repair.
Still not working?
If the checks above haven't restored your led backlight, this usually needs a technician. Our TV Backlight Repair service covers exactly this fault.
