If the digital convergence module is defective, it will not cause R7013 to burnt again. I would suggest to check the solder joints on pins # 12, 13 and 14 to make sure there isn't any solder bridging causing the new resistor to burn.
Let me know if you need further assistance.

    The pins to check for bridging are 12, 13 and 14 of IC7001.

Television has double images like 3D, and bottom half of screen has a concaved image.


Hi,
Please replace convergence ICs in tv, there are two big black ICs that has number STK392-110 mounted with big aluminum heat sink, replacement these ICs will solve your tv problem. Also check big resistor nearby these convergence ICs and replace if found burn mark or color faded.
On circuit board, IC location number is IC7001 and IC7002
Let me know if you have additional question.
Thanks.

Replacing STK Modules in a Panasonic Rear Projection HDTV


Hi there.

If you look up the datasheets for the 392 series, you'd find more differences than power and voltage ratings... Using a similar IC (even if it is the same series) may make it difficult, if not impossible, to converge. It's recommended to change the 2 ICs as a matched pair. Since one already is failing or failed, the other probably isn't too far away.

The resistors mentioned are to bias each output stage for proper deflection and must be within tolerance. They're precision blue flameproofs, so if anything really heated up from a bad IC you'd easily catch any browning / burning. Red is IC7001, blue IC7002, and green is split between the two ICs.

Tha advantage getting a factory supplied or authorized distributor part is you know the LOT NUMBER has been approved by the manufacturer. Generics or unusually cheap originals are often rejects from the manufacturer as being out of tolerance.

The originals are only $29 each directly from Panasonic. Why go through all the effort tearing the thing apart twice to save $30?

Good luck, Mark

The actual Convergence amp ICs not located on the convergence board are probaly what killed the origional convergence module, and likewise has killed the new board. You will need to change the convergence ICs first then replace the convergence module.
I would recommend getting the service manual . I can post a link if you would like.

If it's really bad and happened all at once, your convergence amps have failed would need to be replaced before you could correct the issue with an adjustment.

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?
