Symptoms
- No picture, no sound, no lights
- Power light doesn't come on
- Remote does nothing
- TV worked fine before an outage or storm
Likely causes
- CommonOutlet, power strip, or power cable issueA dead outlet or worn power cable is the most common reason a TV shows zero signs of life.
- CommonTripped internal surge protectionA power surge, especially during a storm, can trip a protective circuit that needs a reset.
- PossibleFailed power supply boardA blown fuse or fried capacitor on the power board stops the TV from starting entirely.
- PossibleDead remote batteries with the TV actually fineRule out the remote before assuming the TV itself is dead.
What to do
- Plug a lamp or phone charger into the same outlet to confirm it has power.
- Try a different, known-good power cable if the TV uses a detachable one.
- Check for any physical button on the TV itself (not the remote) to rule out a remote or batteries problem.
- Unplug the TV, hold the power button for 10–15 seconds to drain residual charge, then plug back in and try again.
- Look for a small reset button on the back near the power input, common after storms or surges.
- If you smell burning or see scorch marks near the power input, stop and don't plug it in again.
- If none of this works, the power supply board likely needs professional replacement.

When to call a pro
If the outlet is confirmed good and the TV still shows zero signs of life, a technician should check the power supply board or internal fuse.
Safety
Use caution
If you smell burning plastic or see scorch marks near the power cord, do not plug the TV in again; unplug it and call a technician.
