Sounds like burn-in. Yep, LCD TVs can have it too. If you look close, I would bet you will the channels that has the bars down each side line up pretty good with that shadowy line.I guess is Samsung TV I have spoken with Samsung about this issue in the past, they will not cover it.

Even though it's not Samsung TV,you can contact the service repair teamfor the make of you TV they will help you out.

Also,Is it an LCD or DLP? Sounds as if you have the dreaded light tunnel collapse common to all DLP TV's. Inside the light engine there is a square tube made up of four mirrors. These mirrors deform and crack with the heat of the lamp. They fall down over the light aperture and cause a shadow of varying degrees. It is fixable now at a realistic price ( used to have to replace engine) have made the parts available. It would take a competent tech around three hours to complete or if you are technically minded you could do it yourself. I hope this helps. Good Luck.

    Hello,

    Your
    power supply board is not yet dead, u know basic electronics' and
    soldering? Most of the times, the power supply board just have dead
    leakages gases capacitors.These capacitors always bulges up on it top,or
    puff up on it top.Replaced these gases leakages capacitors will get
    your TV power stable,and work again.Or tries websites like
    Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for
    the replacement.

    It will require a replacement of the high voltage flyback transformer and perhaps replacement of the horizontal output transistor - usually done at the same time. The cost will be over $150. If you really like the set it is worth it. If you were thinking about a new set with the advanced technology such as wide screen and hdtv reception, now would be a time to think about it.

Horizontal lines on Screen


here's something you can try...remove the back and notice that there are ribbon cables (FRAGILE!) on the right and left side...alot of times these cables develope bad connections and cause the lines you see...other times the panel will be suspect. Removing these ribbon cables and reseating them have helped me determine in the past if it is a bad connection...or a bad panel
