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.

Hitachi 50SBX78B Horizontal lines and bow


John, Hitachi site is down at the moment, if you remove the clips on the front of the IC`s you will see the numbers of the convergence ic`s, and yes they are a pain to get out, they are probably stk 392-110`s if they are the originals, you`ll have to un-solder 36 pins total to get them out, check for burnt resistors in the general area of the ic`s and replace any that are burnt before turning the set on,be sure to order a tube of "heat sink compound" to apply to the back of the new IC`s, once on the set will probably still look poor, this is normal, run the set for minimum of 15 minutes then push the " magic focus button " inside the front door panel, after it has finished running magic focus it should look great, video-tek

Horizontal Curvature with convergence problem


DA, convergence circuit has failed, the IC`s and possibly a couple of support resistors need to be replaced, your right about it being a good set, 6 years is about average for convergence IC`s, call your local shops for a few estimates and get it fixed, it will run for a lot longer than 6 years, hope this is the advice your looking for, e-mail me if you have more questions, BMW Rider

Right side convergence


A convergence IC has burned out. If I remember correctly, those Pioneer sets have one huge convergence IC, but that IC only has 5 channels in it so they use another smaller dual STK IC and one half of it is used for the 6th channel and the other half is the vertical output. Look on the convergence board, find the blue convergence jack, identify the blue horizontal channel, follow the traces and replace the IC handling the blue horizontal channel.

Distorted Color and geometry of Picture


I've posted this solution several times but here goes. Try setting up the convergence through the menu by accessing the convergence setup menu. If this fails to work you have a bad digital convergence box and need a tech to replace it. About $60 to $100 fix.

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?
