I have a 42" Vizio picture has an annoying thick red line

The oven paper (referred as ovenable paper some time), is made of wood pulp, coated with food grade silicone oil. It features in smoothness, high-heat resistance and non- stick, etc. The brightness of baking paper is over 88. The sizing value of baking paper is above 0.8.Its strength is more than 3000.

Your plasma screen is made up of 1080 verticle lines and now a few of these lines are not working. This is the screen itself and needs replacing.

its most likly caused by either vert controler along bottom of set or ribbon to that part of the controler if you heard a hissing sound most likly is the controler itself

You will need to replace the control board and your TV will be better that a new one.

I had the same issue. I could get the tv to work intermittantly by pressing on the boards while playing. This points to bad solder joint, so I resoldered every molex plug connector, and it nows works like a charm.

The panel is almost certainly bad. The only fix for this is to replace the whole panel which would cost more than the whole TV.

If the line is horizontal then it could be a y-drive panel ( depending on from ctr where it is ) whether it is the upper or lower board. Time to let a service company look at it, don't wait, more damage is possible the longer you play it.If it goes vertical ( up & down ) then it could be one of two buffer boards.

1. Frist on the BURN MODE.
2. Check whether same
Vertical lines on screen ?? 3. If yes ..?
4. Then change the LOGIC BOARD or PDP

if you can still see the picture its most likely the control board that's going bad, you will still need a tech out to fix the issue.

IF THE LINE IS ABOUT 1INCH WIDE THE CHANCES ARE IT WILLBE YOUR PLASMA DISPLY THAT HAS GONE . WOULD BR CHEAPER TO BUY A NEW UNIT . HOWEVER TRY RINGING HITACHI EXPLAIN THE FAULT COMPLAIN THAT IT SHOULD OF LASTED LONGER THAN THE WARANTY AND SEE WHAT THEY WILL DO ABOUT IT
