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

I have a PT-53WX42F that I got broken for free 2 years ago, but fixed it by replacing the convergence IC's (it gave 3 flash code at that time). Today it failed to start and gives a single flash code... I understand this is the +140 section, but I cannot identify that on either circuit board, and I see no visible damage. Any suggestions on how to proceed?

Thanks.

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.

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.

PT-53WX42F Panasonic Cinemavision Fresnel / Lenticular screens for cheap


That was an expensive mistake, sorry to hear about it.

I checked with the factory and not all 3 parts you need are available any more... Unless you can find someone junking a similar set with a bad chassis, you may have difficulty fixing your's.

Good luck in your search.

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.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. 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.
