Question about Panasonic PT-53TW53 53" Rear Projection HDTV-Ready Television

1 Answer

Convergence problems I have convergence issues with my Panasonic PT53WX52 TV. I have read that it could be the convergence amp? Can you tell me if the STK392-110 wil work in my TV? How many? From which vender and do you buy the cheapest one, or does it matter?

    Opened up the unit, I have two STK392-110. Am going to order both. I can not read the values of the resisters, they are unreadable. It looks like they are not all the same. Any idea how many and what kind they are? I don't have a schematic.

Replace the cable from your cable box to television. Try one from one of your other cable boxes before buying one, but I highly suspect the actual cable from box to TV is bad

My Panasonic PT53WX52F has a sideways hourglass picture with the green scroll running in an arc with the same red scroll running straight across. Is this the convergence chip you talk about?


There are two common problems with these sets.

Problem #1) Convergence

Symptoms:
  • Screen Looks 3D
  • Colors wont align
  • Video may look distorted
Problem #2 CRT Fluid has clouded over. Symtoms
  • Dull looking video
  • White looking video
  • Halos around objects
  • Red/Orange looking video

You can see some examples and find a fix here...

Need to know what convergence chips are in Panasonic PT51HX41E


your model has two STK392-110 CONvergence Cs, you will also most likely need at least a few of the 2.2 ohm 2watt convergence resistors. I am posting a link to the actualrepair kit for your model which contains both Convergence ICs and all 6 of the convergence resistors and they send instructions with pictures that show how to do the repair.

Panasonic 47wx53 covergence issues


Is the power indicator flashing three times? If so the Ics have shorted shutting the set down. You will need two STK392-110 convergence ICs. You can get replacement ICs at the following link with free installation instructions.

Not the convergence amps (stk-120's)


Convergence amps require B+ voltage to run them...they originate in the power supply and are fuse protected......then
they are fed to current limiting resistors near the IC's....
These devices must be checked......But,the #1 problem is use
of less than first quality IC's......STK392-110's,-120 and-150 can
be upgraded to STK394-160E made by Sanyo.....I use Hitachi
part # CZ 01341 or save money = buy kit with two IC's and some resistors part # X 480293...........read any of my convergence
repair solutions......................T.

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?
