Sound like your relay is stuck or the cpu turn on line is not working, or you have a short somewere, like a jumper

Would open the back and tap on the relay first to see what happen's, first time I see this.
Meanwhile the force is with you.

Why does my panasonic tc p50st30 tv menu not work, tv will turn on but can not shut it off unless I unplug tv.


I would believe this to be a problem with the lvds cable that goes from your logic board to the main board. If your tv does not have a logic board, then it would have to be incorporated into the main board. A lot of times the connection gets loose on the main to logic board. If you reseat it, it may fix itself. If nothing else, you can pick up a logic board on ebay for around 25 dollars with shipping. It is usually very easy to replace. Most of the time, it's hidden behind the A board known as the Main board. It would probably take less than an hour to put in for someone not familar with the internals of a tv. Just MAKE SURE the tv is NOT plugged into the AC line.

Hi, my Panasonic PT47WX49E rear projection tv suddenly shut itself off. It won't turn back on at all unless I unplug it and plug it back in. However, when I do that, the power light comes on but nothing...


Either give me a yahoo or note if light on front of set blinks--count the blinks if it does.

most common is 3 blinks, pause 3 or 5 blinks etc.

Let me know if I can assist you.

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?
