    Hi. I hope this is the right newsgroup for this question, if not, please
    direct me to such.

    Anyway, I have an older Compact VHS camcorder - JVC GR-AX940. After turning
    it on and looking through the viewfinder, I see no picture either in record
    or playback but a white screen. The camcorder itself still works when hooked
    up to a tv. I get sound and picture just fine on the tv but glancing down
    into the viewfinder just shows a white screen, so it seems there is
    something wrong with the viewfinder itself. I went through the manual and
    found nothing in troubleshooting and can find nothing on the web.

    The camera is about 6 years old now and has worked fine up to this point.
    What would cause the viewfinder to go and is there anything I can do?

    Thanks

    Likely the mass surface mount capacitor failure is setting in, could be just
    a cracked solder joint though.

    Ok, next dumb question:

    What the heck is "surface mount capacitor failure"?

    I'm completely non-tech when it comes to this stuff. Could you explain what
    this is in english and if its expensive to fix?

    Cheers

    It means a component which the camera contains a couple hundred of is likely
    beginning to fail, and when one goes the rest are often not far behind.
    Parts are cheap but it's a very labor intensive fix, you'd have to take it
    in for an estimate though, if you're non-technical there's nothing you can
    do.

    i opened up a panasonic one a while ago with the same problem
    in the viewfinder.(didnt connect it to the tv though)
    about half the capacitors i tested were bad. the rest were probably on
    their way out.
    i tested about thirty of them before i decided it was going to be too
    much work.
    i would follow James's suggestion and have a look for a cracked solder
    joint or broken wire first(especially if the viewfinder is one of those
    ones that move up/down.
