DIY Solutions
Verify and restore power connection
- Ensure the TV power cord is fully plugged into the wall outlet and the TV.
- Test the wall outlet with another device to confirm it supplies power.
- If using a power strip or surge protector, try plugging directly into wall outlet.
Check and replace remote batteries
- Remove old batteries from remote.
- Insert new batteries in correct polarity.
- Attempt to turn on TV using the remote and also the TV’s physical power button.
Perform a power reset on the TV
- Unplug the TV’s power cord from the outlet.
- Wait 5–10 minutes to allow capacitors to discharge.
- Plug the TV back in and attempt to power on.
