Replace......do not bother to check C424 & C425

That should alleviate the problem.

Hello,
I can't be the only one seeing this problem.
Have a JVC Model AV-27230 with what looks like a collapsing Vertical
Screen at the top, similar to what you'd see when a Vertical Output IC
goes sour on most sets. In this case though it is Translucent, most of
the time, on most channels/backgrounds. Occasionally it is collapsed at
the top in the traditional sense, as in it's not Translucent, but
Black where it's collapsed.
Doesn't matter what is used for a video source or what input source is
used, e.g RF / Tuner, Video 1, Video2, etc.
If I wasn't so picky I could probably live with it when it's
Translucent, but you know how that goes..

Found this someplace else regarding how to get in to Service mode on
JVC Sets...a bit hesitat to try tweaking anything until I understand
what is going on here...e.g.- Could it have something to do with the
Vertical Deflection on the Yoke??

"With TV powered ON press: [DISPLAY] and [VIDEO STATUS] on the remote
at the same time.

-or-
Press the [SLEEP TIMER] key and set the SLEEP TIMER for "0" MIN. While
the SLEEP TIMER information is still on screen, press the [DISPLAY] key
and [VIDEO STATUS] key of the remote control unit at the same time to
enter the SERVICE MENU.

Exit the service menu by twice pressing the [EXIT] key on the remote.

If you're attempting to adjust color or geometry errors, you'll need
the Video Essentials DVD, Laser Disc or some other source of test
material."
