Hi! I have the same problem with panasonic!

Hi! i think I have the same problem with panasonic, I have PT - 53WX42F projection TV and when I turn it on it works for 3-4 seconds then shuts down and blinks 3 times and then in 4-5 seconds blinks one more time and that's all If I press power button again I cant do anything untill I unplug the wire from the power and then it repeats. I got this TV from my friend and noticed that he replaced STK 392-110 on the A-Board and I saw 2-3 shortcuts on the board while he was replacing them so maybe I think it is some automatic guard been worked so maybe I need to replace them (STK392-110 2 pcs) again? How did you fix your problem if you did and what was the reason? I would very appreciate your help to me ! Thank you ! 407 285 33 55 autocars4u@aim.com :)

SOURCE: Convergence IC

Yes, you can, but the -010 is the weakest IC and may not last long. I always use the -020 IC and never have problems.

SOURCE: TV shuts off automatically

I Can Assure You That This Problem Is Associated With 2 Capicators On The Power Supply Board.

SOURCE: NO PICTURE, NO SOUND, TV TURNS ON THEN TURNS OFF

STOP THE PRESS!! I FIXED MY TV for a whopping $26.

I took a wild shot and purchased two STK392-110 convergence amplifiers from http://www.electronix.com/. They ship fast, placed my order on Tuesday evening after coming here and placing my comment. To my suprise the parts were in my mailbox on Friday. The parts were actually $12 but I also picked up a iron and a solder sucker.

So rarewish4us, If you're in the South Florida area I'd be more than happy to take that "JUNK" off your hands. LOL
If I were you, I'd give it a shot before you junk it.


Good luck,
Howie

SOURCE: Can't power up

The buzzing noise you are hearing is most likely the ballast fire, this is good. You most likely have a bad lamp which is the best case for you. I would recommend pulling the lamp out and looking at it to see if its physically shattered or not.

The instructions for pulling the lamp can be found in your owners manual. If you do not have this anymore just look on the sides or the back of the tv for a small door with a screw or 2 in it. take those screws out and the door should come off, then take the screw(s) out of the lamp and pull it out. if you see glass rolling around inside you will need a new lamp. Let me know and I will help you find a good one at a good price.

SOURCE: removing STK-392-110 chip

Hi, they overheated and are really stuck to the heatsink compound you will have to use a flat blade screwdriver and a hammer and tap them until they break loose, be SURE to remove the old white heatsink compound before you apply the new compound to the new stk`s, you did purchase a tube of heatsink compound for the new stk`s right? No compound = cooked stk`s in 6 months, good luck, video-tek

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.

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.

Resistor


electronix.com or matelectronic.com should have that resistor. Be sure to specify flame resistant 5% tolerance that is a convergence resistor so it needs to be flameproof and install it up off the board like the origional was.

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.
