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

1 Answer

Red convergence is off.

I have a panasonic PT-53TW53 53inch rear projection. I was watching a blu ray movie and all of a sudden the red was way off alignment. I tried to adjust via menu, but it wasn't even close. I did a little research and assume it's an IC problem? I'm pretty good with electronics any help would be much appreciated.

Hi there, your problem does sound like the IC's or IC has gone bad, before you change them check the solder connections. If they are ok then the ic.s need changing, do both as the other one may fail shortly, they are usually STK392-110 but check the number on the ic's to be sure. then do the alignment that covers the whole screen, sometimes you get lucky and dont have to go through the fine adjust. hope this helps.

Missing red composite signal on panasonic pt-47wx52cf


Check your jacks and cables.

The RED jack is either (1) left or right channel AUDIO signal or (2) the RED color channel of an RGB (Red, Green, Blue) COMPONENT video signal.

Yellow is the COMPOSITE video signal.

The convergence ICs have failed. You will need to install a convergence repair kit. You can get the convergence repair kit for your model Panasonic from www.tvrepairworld.com which contains both of the Convergence ICs , the associated resistors and the cD with detailed repair instructions.

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?
