    Hi,

    I have a Panasonic TV/VCR PVQ-2511 (mfg 07/01) in
    my shop with no color problem (good B&W picture). What
    I would like to know, is there a way to service the "mother"
    board (scoping the printed circuit side) without the VCR
    connected?

    In order to scope the traces, I have to remove the board
    from it's "holder", which is the holder/support for the VCR.

    Thanks in advance, Brad

    Hi
    are you using a scope, Digital or Analogue Meter?. There can be a difference
    due to the waveform. I am not sure what to expect at flyback frequencies. I
    am only happy when I get the same voltages as on the circuit diagram
    (schematic)

    May be a dumb question, have you tried going into the menus to see if the
    color is turned down? Kids are great for things like that.

    Can you remove the crt and scope from the top of the board

    I remember that I fixed this problem to replace Y/C Jungle chip small
    SMD IC on the board.
