Question about Panasonic PT-53TW53 53" Rear Projection HDTV-Ready Television

Convergence Shutdown - instructions how to fix?

My PT-53 went green briefly then the screen turned off. Power light blinks 3 times in a row, repeatedly. I guess I need to replace the IC?

I see that MCM carries the part stk-392-110, but I read other places that the 150 is a better one to use?

Is there somewhere with step by step instructions how to open the tv, where to find this part inside, and how to replace it? I have some soldering skills, though nothing great. How many do I need to replace? Thanks!

Yes the STK 392-150 is a better quality IC. You will need to replace both of them. Also if you purchase the ICs from the link i am posting they provide free instalation instructions with pictures and also have free insatant messageing tech available which is completely free. I am one of their support techs and they are a good site heres the link if you want to check them out.

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.

Blinking power light


Hi,
Power light blink 3 times shows that convergence out ICs got defective and need to be replaced.
If you are handy with electronics stuff repair and can solder parts in circuit board with proper tools then replace two big black ICs, convergence out, mounted on aluminum heat sink.
Or call local tech to fix it.
Let me know if you have additional question.
Thanks.

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?
