SOURCE: vertical green lines

Call where you bought the TV. This is not normal for an LCD TV. They should exchange it only being a week old.

SOURCE: 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.

I CANT ADJUST THE RED VERTICAL LINES ON MY JVC REAR PROJECTION TV. i HAVE DONE CONVERGENCE AND MANUALLY ADJUSTED THE RED LINES HORIZONTALLY, BUT NO LUCK WHAT CONTROLS TO USE VERTICALLY


If it will not adjust up or down or left and right the convergence chips need to be replaced.

See attached photos of board that is in your set:

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.
