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?
Bought it brand new about 4 years ago
No work has ever been done to it
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. You can use the link below to locate a tech if you do not have experience measuring live voltages and soldering inside of a TV.
