horizontal lines on TV (1 Viewer)

[Truan]

I just bought a Sony 30" widescreen Wega TV, and when I got it home I noticed two horizontal lines, one toward the top and one toward the bottom, runnuning the entire width of the screen. They are extremely thin, and no picture comes through them.

I was in a showroom last night and noticed that all the other flat screens had them, too. But when I got home, I noticed another one on mine, near the center of the screen.

Not sure if they are scan lines or what, or if it's normal or I need to exchange the TV. I haven't called Sony yet. Does anyone know what these are?

Thanks.

These are common on Sony Trinitron (and others) flat screen TV's and monitors. I have them on my Sony computer monitor at home. Rest assured they are normal.

Thanks very much. Makes me feel a lot better. I was afraid they'd start multiplying like Gremlins.

they're the trinitron lines. Trinitron sets don't use grille aperture shadow masks, they use vertical strings of sorts, and to stabalize them, a few horizontal strands are run as well. On small screen you may find one of these, on larger screens you may find a couple more.
