Panasonic PT-53TW53 53 in with bad picture


Sounds like you need new convergences ICs. There are two of them in your set sometimes you can get away with just replaceing one of them but I wouldn't recommend it. They are not too expensive are 15.00 each once you replace them you have to get into the service mode and adjust the convergence.

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?
