If it is completely dead (no standby light, flashing LED blinks), the power supply failed. Replace the Power Supply board to fix.

No power on tv


Hi,

I'll think there's a problem with the power supply.
Maybe there's a blown fuse inside, that would be the cheapest solution. If not, you need a repair centre.

Kind regards,

LG TV completely dead


Hi,

I'll think your power supply is down.
Since your tv is 15 month old, you've still got waranty left.
Just contact you supplier or LG service.

Kind regards,
