JVC LT23E31BJG 23 in LCD Flat TV Problem: Recently a thin blue vertical line has appeared on the screen about 5 ins from the right hand side. It extends the full height of the screen and is present all the time while using tv or dvd player.

SOURCE: Vertical, pencil-thin blue line appears after 10 minutes of viewing (any source)

I would suspect a connection breaking down as the set heats up. A shop will probably have to put the set in a stand to hold it while they check for loose connections or defective components inside. Not a DIY job by any means. If this line went completely through the picture either vertically or horizontally and stayed there then this would have indicated a failure in the Panel itself. A thin Line any where on the screen consisting of one pixel in width is a Panel Failure according to Hitachi.

First, HORIZONTAL CENTER.
1) Press MENU.
2) Scroll to SETTINGS.
3) Scroll to SCREEN.
4) Go to HORIZONTAL CENTER. Move the picture to the right. Hopefully, the line will go away. Otherwise, there is a problem with the pixels or the signal processor. Call 1-800-222-SONY. Or, http://eservice.sony.com. Have a high-limit credit card handy for out of warranty repairs. Sorry about that.

is this a rear projection tv? a table top one? how old is it because if it's over a few years old, then it sounds as if the bulb may be going out but without having more info, it's hard to give an accurate advice.. please let me know if this helps..
