Hello, My name is XXXXX XXXXX I will be glad to assist you.


I'm sorry to hear about the problems you're having with your TV.


Is there a steady, or blinking light at all on the front of the set?

If it's blinking, is it continuous or in a pattern (like 4 flashes then pause, then repeat)?

Customer: replied 6 years ago.
The power light comes on and then goes off, no picture when it comes on. Keeps turning on and off every few seconds
Expert:  Aric replied 6 years ago.

Thanks for the reply.


I'm trying to find out as much information as possible to give you an accurate answer.


Have there been any power outages or storms in your area recently?


Also, was there a loud pop or other incident worth mentioning prior to the set not turning on?

my son and his friend kept turning it on and off and then he turned off the surge protector.
Expert:  Aric replied 6 years ago.

Thanks for the reply. This will kill the power supply in short time, more specifically the capacitors. They receive an influx of current when the set is powered on, and discharge when the power is shut off. Cycling them too fast will cause them to short internally and not allow the set to come on.


This requires component replacement on the circuit board. The common cost to replace the caps is around $120 parts and labor.
