An LED TV that won’t turn on at all is most often caused by a problem in the power path: the socket, the power cable, a fuse, or the power supply module inside the TV. Another common cause is a mainboard fault, often after a power cut or a voltage surge. Check the power source safely first, and don’t open the case yourself because some parts carry high voltage.
What causes an LED TV to go completely dead?
| Cause | Typical sign |
|---|---|
| Faulty socket or power cable | The TV works again on a different socket |
| Blown fuse | Often after a power cut or lightning |
| Failed power supply module | Standby light off, sometimes a burning smell |
| Mainboard fault | Standby light on or blinking, but the TV won’t start |
| Backlight failure | Sound but a dark screen (not completely dead) |
Safe checks at home
- Try another socket and make sure the power cable is firmly plugged into the TV.
- Remove the stabiliser or extension strip and plug straight into the wall for a moment.
- Watch the standby light. Note whether it is off, on or blinking, because it helps the technician.
- Use the power button on the TV, not just the remote, and replace the remote’s batteries.
- Unplug for 5 to 10 minutes, then plug back in and try again.
When should the TV go to a technician?
- Still no response after the steps above.
- A burning smell or a popping sound.
- It died after a power cut, lightning or contact with water.
- The standby light keeps blinking in a pattern.
If you smell burning, unplug the TV and don’t switch it on again until it has been checked.
