  • Use another large device and plug it into the wall socket. Check if that device is working properly. 
  • Now unplug the device and plug your TV back into the wall socket. Turn on your TV using the physical buttons on it. 
  • Solid Red Light: It means there’s not enough power voltage for the TV. 
  • Blinking Red Light: If it blinks five, six, or more times, repeat the same steps but use another wall socket. Power voltage is not an issue here.

Analyze Internal Damage
