Question about Toshiba TZ50V51 50" Rear Projection Television

1 Answer

I have a Toshiba tz50v51 Rear Projection Television. My issue is with the picture. The convergence is fine but the lines that run from left to right "squiggle". It almost seems like a bad coax cable running from my satellite receiver to the tv but when I watch a dvd I have the same problem and I have rca cables going to the tv from my dvd player. Sometimes you can hear an audible high frequency noise when the tv squiggles and the intensity of the squiggling depends on the picture. Is there a fix for this problem?

Hi,
Since tv is 1999 model and most likely it got problem of dried up electrolytic capacitors in EDS/NEW OSD module that is located on signal board (inputs and tuner board). Replace all capacitors on that module to solve the issue.
Capacitors replacement need soldering work with proper tools and if you feel uncomfortable doing so, ask local tv tech to hep you out.
Thanks.

    "The EDS/NEW OSD module on signal board(inputs & tuner board)" Is this the board that has the RCA, Coax, etc. inputs tied to it. If not is there a serial number or another way to locate this board. Is it possible to just remove that board and take it to a tv repair shop rather than bring a whole TV? Thanks again.

    Yes, signal board that has Coax, RCA jacks and EDS/NEW OSD board is mounted on signal board, its connection pins are soldered with circuit board, it is not plugged there so call a tech to fix it or take tv in because an expert in soldering work can take this board out without any damage.
