Hi

Thanks for using FixYa. If the TV isn't turning itself on then the fault protection circuit has detected a fault and has turned down the TV. You'll need to check various things to find an answer which part is bad. Please check these---

1. Check for signal cables at the back and also try unplugging the TV for 8-10 hours to reset it.

2. Swollen /bulged capacitors on the power supply board-- This happens due to overheating of capacitors.

3. If the capacitors are fine then you'll need to check for connectors on all the boards and also the fans if they are working fine.

4. Make sure the lamp connections are fine and ballast is not burnt.

Note-- Please make sure to turn off and unplug the TV for at least 1 hour (this will drain off current from all components especially capacitors) before you perform any repairs. Also note that the TV consists of very high voltages even when it is in OFF condition.

Try to reset the TV by unplugging it for 8-10 hours.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks

Rylee
