Try removing and re-installing the lamp cover on the back.
may be the lamp cover is not seated properly causing the safety switch to not engage all the way, when the lamp cover heats up and expands, it fall away further from the switch tripping it, shutting the set down.
when you remove and re-install the lamp cover, after you take the single screw out, tilt the cover out and forward from the top about 3/4 of the way out and then tilt it back into normal position and put the screw back.

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 the kit contains the parts and the CD with instructions for the repair.

Panasonic PT-53WX42F does not turn on, gives single flash code

my tv had the same problem and the B+140 was low. When I measured it, it was 89volts unfortunatly led me to the Flyback tra$former. after alot of troubleshooting work, I realized that the primary is short circuited. Also the horizontal output xsitor heats up alot on start up, thankfully it doesn't blow :)

I've had panasonic flybacks do this before to me. I havn't replaced my Flayback yet but when I pony up the $65.00 I expect (and pray) the TV to work fine. There is an off chance that something like the splitter or the foucus block caused this failure, but I doubt it.

PT= 53WX42F

Does it blink 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.

  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

You need to replace the convergence chips and convergence resistors. Check the site They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.
