Your tv is shutting down and going in to a protection mode to protect itself from damage. The light blinking 3 times represents high voltage shutdown, usually occurring in the convergence IC's and support componets of the tv. It is known as a common problem. Sorry its not a consumer fix for its a major fault in the circuitry. But if you have knowlage it can be repaired. If you take it for repair it will usually run about $300 to $400.


If you try to work on this kind of tv precede with caution because they are high voltage.

If it is blinking three times if so its a convergence problem -your set uses stk392-110 i usually replace with stk392-150 or stk392-180 these are more stable. if you have no soldering experience or electronic experience. but if you want the challenge go for it. remember that there can be several thousand volts in this set even when unplugged.

Its convergence failure problem and causing 3 time blinks.
TV requires replacement of STK392-110 to fix it.

Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672

Hello, I have a 53-inch Panasonic PT-53WX42F TV, and it refuses to turn on. No picture, no sound. All it does is the tiny red power light blinks 3 times repeatedly. Can I fix this myself? What parts do I...


Thats a convergence failure when the led blinks 3 times. Your model uses the PT47WX42 convergence repair kit available from www.tvrepairworld.com the kit contains the parts and the CD with instructions for the repair.
