Panasonic MODLE PT53TW53G led code flashes 3 times convergence problem

I need help!!!!!! I got up and pushed the on button and the TV would not come on and the red led flashed 3 times and stops and then repeats the steps. What could the problem be? I heard that it could be the ic`s in front of the heat sinks so I took out the board but nothing appears to be burnt. But some one said this is a common failure. I also checked the surrounding resistors .and everything appears to be ok there is no discolor on the board except around some diodes and they seam to check out ok. What do you think the problem is?I am not 100% sure if i checked the right resistors ? or if i got the right value on them

Panasonic PT-51HX43G no power, red light flashes


I have a Panasonic PT53TW53G projection tv that had the same problem for power .A terrific person gave us wonderful advice and it fixed our tv! We were told to replace the IC conversion amplifiers. On our model they are STK392-110 (your's may be different). We ordered the parts from www.electronix.com and they were only $12. for the two parts. We also had to purchase a soldering iron and de-soldering vac for removal/replacement of parts. Good Luck!

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?
