Is it worth repairing ~8 years old JVC K-series 29" TV. If the screen is receiving 16x9 theater broadcast, lines are not at the top of the screen. If it's a standard tv show full screen, about ~10 white lines appear, not real bad, but enough to be annoying.
Stationed in Europe and not sure if to purchase Flat Panel and worry about shipping it back when returning to U.S, or to hold off and just fix this one to last ~8 more months

you have some capacitors in the verticle circuit that are failing they would require replacement to correct this problem est 125 or so to repair and probably still a worth while fix but with the price wars for Holidays upon us you you may want to look and see what you can get with just a bit more money i hopw this has helped
Vertical defection failure. Common failure. Pretty easy to
repair ($50-75?). However, my general rule of thumb is not to
waste any more money on TVs over 10 years old. Too much other
stuff in there ready to fail as well.
It sounds like a vertical deflection problem. You mentioned you had a white HORIZONTAL LINE in the middle of the screen. If this line runs from left to right across the screen it's in Verticla deflection. If it runs from top to bottom, it's in Horizontal deflection. I am assuming the problem is a Vertical deflaecion problem. The repairs necessary are most likley to replace the vertical capacitors or the verticla deflection chip.

Seems like a simple problem. In all likelihood, one of the Electrolytic Capacitors in the vertical Output stages has failed.It could also be a cold / dry solder, as symptoms seem to disappear when you tap the set.
But, do not try anything thing at home. A proffessional Techie should fix it up in 15-20 mins.
Definitely worth the spend.
