    Where did you get the ic's and what did you pay for them?

    I have had this exact problem and it was the STK IC's that I bought were cheapies and they could not handle the current. I replaced them with the panasonic IC's and it came back to life. You can respond to this post and I can help you if you have any further questions.

Panasonic PT-47WX53 has intermittant convergance issue


I would chack the solder connections at the convergence ICs first. Since the set "recovers" on its own, it suggests a connection issue rather than a defective component. Also, if the ICs were installed without sufficient heat sink compound, this could happen as well. Look at low valued resistors in the area of the ICs for signs of overheating as well.

Keep us posted on your progress.

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.

Sounds like your convergence chips are going. Unless you are real handy with soldering iron I would suggest having a tv repair shop service it(probably cost $200-300). If you are handy then I believe the chips you need are Sanyo STK392-110. There should be 2 of them. be careful if you order them online, there are lots of chinese knock-offs out there.

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.

Your TV most likely has a Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • Screen looks 3D
  • Colors don't line up
  • 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 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.

Has anyone had problems with connecting an 'HDMI to HDMI + SPDIF + RCA L / R Audio Extractor Converter (HDMI input,HDMI+ Audio output)' to a Panasonic PT-53TW53? I have a TiVo Premiere hooked up to my Panasonic PT-53TW53. I use the HDMI out, and RCA R+L outputs on the TiVo, and hook up to the digital in connections on the TV. The conversion of the HDMI out is via an HDMI to DVI cable. This has worked perfectly for years, but recently I wanted to disconnect the TiVo and replace with my Roku or Amazon Fire TV. Both have a single HDMI output. So I purchased an AGPtek HDMI to HDMI + SPDIF + RCA L / R Audio Extractor Converter (HDMI input, HDMI+ Audio output) box, hooking up the HDMI output from the Roku or Fire TV to the input on the extractor/converter, and simply disconnecting the HDMI to DVI and RCA R+L outputs from the TiVo, and plugging them into the outputs on the converter/extractor. The converter/extractor has a 3 position switch: PASS, 2CH audio, or 5.1CH (via and SPDIF or Toslink cable). I have had 2 of these converter/extractors, and with both the Roku and Fire TV I got the same results with both converter/extractors: With the switch on 2CH, which is where I understand I should get HDMI video and 2CH RCA audio, all I get is the RCA audio. No video. If I switch to PASS I get video with no audio. Of course on the 5.1 setting I get nothing, since the TV does not support SPDIF. Yet I see reviews all over Amazon indicating folks are using this converter/extractor for this very purpose, and it is working fine. I can't possibly imagine that it is some sort of incompatibility issue with the TV, since the TiVo has worked (and continues to) fine for years. Any ideas?
