TV is showing blue and green mixed double images .


Hi


Thanks for using FixYa. The issue is with the failed convergence (STK) ICs which needs to be replaced. It’s not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you’ll have to open the back of the unit and then replace the ICs (STK ICs) which are located behind the black heat sink and also check the resistors as if they are short the ICs might blow again after sometime. There are repair kits available which includes repair instructions with the parts, if you want to do it yourself, you can buy and repair it yourself.Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thanks

Double vision on the words with blue tint


Convergence failure. The PT53WX53 convergence repair kit available from www.tvrepairworld.com will usually repair that issue. The kit contains the Two ICs , six resistors and the CD with repair instructions

did you check the low ohm resistors? Its not uncommon for some of them to be opend when the ICs go out.

Burnt resistors


Depending on where you bought the ICs you could have fried the new ICs when powering it up with burnt resistors as the green is controled by both ICs one IC controling the horizontal green Convergence and the other IC controling the vertical green convergence. Have you checked all the convergence resistors out of circuit?

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

Convergence


Did you remove 1 leg of each resistor out of circuit when you checked the resistors? sounds like thier is still one resistor open or maybe one of the new IC pins need abit more solder.

Convergence


Next to the ICs you will see about 6 or 7 resistors with no color bands usually green in panasonic they all look identical. Check them with a ohms meter to see if any are open. The ICs usually take out one or two of these resistors when they go out.

PICTURE NOT SQUARE


Most times when that models Convergence ICs blow they take out at least one of the resistors on the board right next to the ICs. They are easy to spot there are about 7 of them they have no color bands and they are all identical either light blue or light green. Look at those resistors you will no doubt find at least one maybe two that are open. they are rated at 2.2 ohm 2 watt and at 5% tolerance this is marked with a J on the resistor. Let me know if you need any additional help.

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?
