    Hi group

    Interesting one this . Works for about a minute then sputters,fades
    out and goes dead , "chirrups" on startup after that .

    This is a JVC VF-V7E as used on the VideoMovie series GR-45E .

    Solution - remove the HV lead by unclipping the four clips on the
    front of the CRT, and carefully levering up the piece of plastic where
    the white paint (retainer) is , pull off the HV lead . Thoroughly
    clean the area and lead with IPA and allow to dry .

    Worked for me :) The connector pinout is :-

    1=video
    2=gnd
    3=+8V
    4=Gnd

    viewed from pin side of plug.

    Gotchas on this one - check supply voltage if focus and geometry are
    way off . Has to be exactly 8V on these units .

    Connections are the same on the VF-V7E and they should be
    interchangeable in theory .
