    Z-sustain: From a bad board, to a sparking power supply board, back to good!! VIDEO

    Howdy all!! hard to believe its been over a year ago now since I dipped into the "repair flat screens as a hobby" game. it all started for me on these forums. I have salvaged several flat screens since my first repair. very rewarding game to be playing.

    Anyways.......the first flat screen i ever repaired was mine. A BenQ46W1, Only BenQ in name as they NEVER designed their own panels. its nothing more then a Gateway P46M103 re branded with the BenQ name. Tatung made the panels. Even though the panel was designed in 2004, there seems to be an endless supply of parts available online (lucky for me) and most of all, very in-expensive.

    Over a year ago my Q-display croaked, I began reading and asking questions. End result was a bad Y-sust. board. replaced it and the panel was trouble free for over a year. Couple weeks ago, it started acting up. WHITE PIXEL flashes when i powered on or off. distorted color (tough to see in the video) but above all, you could hear it sparking inside when powered on or off. it had the classic symptoms of a bad Z-sust. board. But......the sparking had me curious and I was eager to investigate!! perhaps cause this set was my first repair I have an emotional attachment to it?? who knows?? I realize its not worth anything, but for $36 total in parts It was fun to repair it AGAIN

      Good job!

      Man, that was a bad bad solder joint. Those are the ones that start fires! Look at how the solder was pitted from the sparking!
