Can you please doublecheck the model number off the back of the TV?

Also, how long have you had the set for and has ANY work at all ever been done on it?

Please unplug the set for 10 minutes, then try to power back up and see if you get the same blink code.
Customer: replied 5 years ago.

I have already done that and same thing keeps happening.

This blink code (3 blinks of the XXXXX XXXXXght), would indicate loss of the 5 volt output on the power supply. This could be caused by a faulty regulator IC, failed capacitors or a cold solder joint on the power board. Either of these problems will require component level testing and replacement by a certified technician to fix the problem. Average cost for this type of repair is between $200-$300 parts and labor.
