  1. Hello,

    I am hoping one of you electronics gurus could help me out...

    The other night I was watching my Zenith 27" TV (SL2773W), when it
    started flashing green. The picture disapeared for a moment and then
    reappeared, but now everything looks darker, mor of a purple-red tint.
    Images that used to come in yellow now come in magenta. Overall,
    everything seems to have a reddish tint now.

    I looked out on usenet for a thread related to this problem. Here's
    what I found:

    I tried going into the menu like someone suggested. What I saw was
    that the blue letters look perfect, the green letters look perfect,
    but that the red letters, though visibly red, were somewhat blurred.

    So what could this mean potentially? Is the TV dead or is this
    something I can get repaired relatively inexpensively?

    Thanks for your help,
    Leo Hart

    Most likely a bad CRT.... or could be something much simpler like a bad
    driver transistor at the neck board or a pre-driver transistor on the main
    pcb by the jungle chip.
    Some basic test equipment like an oscilloscope and DMM and the proper test
    and safety procedures performed a knowledgeable and experienced television
    repair tech can give you the answer after some brief troubleshooting at a
    repair shop. Only then can you make an intelligent repair decision after
    you get the facts.

    Yes, it could be a drive problem or the picture tube. I'd say chances are about
    99% bad tube 1% drive problem on that model. It's not been one of Zeniths
    better sets.
