There are feeder resisitors that can go when the STKs (ICs) go bad. They might be bad as well. Also check to ensure you have all cables properly connected.

TV is blurry and the red and green look as if the picture is in 3d and I need glasses. Can I fix this myself?


There is almost nothing that can be fixed by yourself if your not trained in high voltages and advanced circuitry now days. This sounds like it could be your color guns going bad or the power supply.
This set also has an issue with The tv convergence board,require 2 STK convergence ICS and some or all it resistors to replaced to solved the tv convergence picture problems.

I have my panasonic tv


This is a convergence problem and is either bad connections at the convergence IC or defective ICs. If you can solder, try resoldering the pins on teh convergence ICs. If that fails to resolve the problem, replace the ICs. These ICs are large black ICs attached to a heatsink and may be marked STKxxx.

Keep us posted on your progress.

Ok, so I Replaced stk-392-110 (2) and......


Check the resistors in the red convergence circuit right next to the Ics you will need to lift one side of the resistor out of circuit to acurately check them but usually one or two resistors will be opened when the ICs go out

Red and Green Spots


Not a fix for do-it-yourselfers, but check with Panasonic as there is a new fix. Requires tech to come and reprogram the eprom (I think).
Cheaper than a new optic board.

Picture shows only about a 2-3" blue,green,or red vertical line down the middle


If your seeing vertical line across the screen you need to check the components in the vertical stage as well as the vertical IC could be bad, or the yoke could open.
Also check if any voltage reaching the vertical stage.

Good luck.

Was this help full.

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?
