Re: video appears distorted--halo like

Check your sharpness setting, it should be very low and even in the negatives possibly on a plasma. I was told the sharpness option was for crt tube tv's anyway

Horizontal black line on my LCD tv

T con board is responsible for digitizing picture info and what you see on screen. Any crazy items, distortion, are derived from there.
See if you can one on ebay - often the boards are parted out from other sets.

AKAI LCT2662N screen problems -distorted

that sounds like your LCD controller, since the LCD screen is so big, they will "split" the screen into 2 smaller screens, otherwise it would be so outrageously expensive to have one big massive lcd controller. Your lcd controller is most likely a two-in-one card though, meaning that there are 2 controllers on one board. You'll more than likely need a new controller card for your tv.

Red distortion

it sounds like your IR board is going out, its easy to replace and is inexpensive usually about 10.00 plus tax and shipping, and very easy to install, its one of the few parts you can buy for these models outside of the 479.00 dollar control box.

I would not suggest you try replacement yourself, as the sheileding on some Plasma TV's can be difficult to remove. You would be better off letting a reapir centre do it, at least you have the work gauarnteed. Try
