JVC TV Model AV-27230
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?? Bill "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." |
