If the band is there constantly and looking the same then the defect is in the LCD panel itself - the tv is gone.

Red vertical line down right side of the screen


hi

I think your TV have a trouble inside lcd panel
the controller board contains driver IC. Deffective driver IC can cause of line display.

Three reasons why one vertical line accross screen can happen in LCD;

1.The missing signal from the controller IC to
LCD driver.
2. LCD driver IC itself defective
3. Dry contact in the tape carrier package.

Use masking or electrical tape to mark it where the line was located. press it if the line back to normal but when release your hand came back i think it was intermittent. Open the LCD panel

Vertical line on my 46" toshiba lcd tv


The only logical solution for the problems people are having for the toshiba regza's tv's is to get into a class action law suite..., they contiue to sell tv's with defective parts and refuse to help the customer that spent large cash to find out they last if your lucky 2.5 years, they are junk and anyone with one will soon find out./.......

DLP TV: Left half normal, vertical 6" band center is gray, right half almost black. What's wrong?


No. The optical engine is OK. You need an adjustment in the light tunel. Call a tech to do it.
