Question about JVC HD-52Z575 52" Rear Projection HDTV-Ready Television

1 Answer

Vertical lines problem

I've owned a JVC HD-52Z575 for about 2.5 years, and in the past year I experienced the following problem: When I power on the TV, thin vertical light-blue lines (about 2mm in width) appear across the whole screen uniformly separated by about 3cm (1.25 inches). When the problem first occurred about a year ago, the lines disappeared after about 5-10 minutes or so. Now it takes much longer for the lines to disappear - maybe closer to 1/2 hour or 45 minutes. The lines tend to disappear more quickly when the TV has been used more recently. Is this a salvageable problem with a proper part replacement? I had a repair technician look at the TV last year when the problem first occurred and he didn't seem to know what to do, and claimed the cost for repairs would be more than the cost of a new TV. Any help would be appreciated.

Vertical lines appear on the screen.

It appears like there is a bad capacitor in the horizontal circuit. Try to put a fan near the ventilation trap, just for a test.
the part cost almost nothing but having someone to your house is expensive.
Your decision.

Usually, if the red light is flashing and you get no picture, that means that the lamp life cycle is finished and you'll have to get a replacment lamp. the lamp has about 3000 hours of life (2 to 3 years under nomal use).

You can buy a replacment lamp from here

Hope this helps

Toshiba 46In HD Rear projection TV Vertical lines on screen

We also have vertical lines with our JVC 62"... turning it off and letting it cool down is the only solution. For us, we know it's a problem with heat. We simply are wits end on fixing it. added two additional fans, a exterior fan to blow heat away from the back of the tv, pulled everything else away, etc.... Anyway, goodluck.
