    Hi Having a monitor Viewsonic that had a blowed vertical IC . I had changed
    it , but now , without any signal , I should see a blinking "no signal"
    pattern but I see large vertical color lines (red/blue/green), like a signal
    pattern (color bar) but blurry.

    With a input , samething .

    The strange thing is when I turn off the monitor , I can see the picture for
    a quick moment.

    I had try to reduce the AC line , samething.

    Help !

    Thank...

    I ll post the model # later today

    Vertical IC replaced is a TDA8172.
