I have a Toshiba 26AV500U purchased about five months ago. We have been very happy with it, except for a couple of niggling issues (the blacks are rather pale, especially at the edges of the screen, and there is almost no viewing angle below the screen level).


We just moved. I hooked everything up and tested it, and didn't notice anything out of the ordinary, but I didn't look closely. Now, a couple days later, I fire it up to play some games, and notice two horizontal pale bars, two or three inches high, one about 30% of the way up from the bottom and one about 60% of the way up. Their edges are irregularly shaped, not exactly horizontal, nor even exactly horizontal in sections. These bars are extra belts of the paleness that appears at the edges of the screen: it's almost like the backlight is too strong, or the LCD insufficiently opaque, in these areas. Turning down the backlight makes the issue less noticeable, but it's still quite obvious on the dark startup screen of the PS3.


This is NOT a signal issue: the bars appear with any signal (HDMI, component, composite, antenna) or no signal at all. All the sources and cables are the same that worked fine in the previous location.


I'm inclined to discount moving damage as a cause, as it was a two-mile crosstown move by competent movers and I don't see any damage to the unit or the packaging.


What could be the cause? Any idea how to fix it, or is this a warranty repair?

My Samsung LN26A450 has horizontal banding when I have the brightness too high. And since the Toshiba 26AV500U is basically the same as the LN26A450, then I guess you should try turning down the brightness till you get a complete black screen. See if that works.
