Since this happens after the set warms up, I would check for bad solder connections or capacitors on the convergence board. If the problem was not readily apparent, then I would consider replacing the board, as I believe the replacement board has been upgraded from the original.

I'm having a problem with the color green being distorted on my TV. Is this a color tube issue, bulb issue, lamp issue?

This is a picture tube type TV. No lamp.
You don't describe the distortion.
A colour green picture that is twisted and shifted away from the other colours is a convergence problem. see Projection TV Convergence on this site.
If the green is smeared, out of focus, larger than the other colours like a halo around objects, things like that, it is the green picture tube. Sony has discontinued most of the picture tubes so you may not be able to get this fixed.

The picture on my 2 yr old Toshiba 42hm66 DLP tv starts flickering and with alot of rainbow looking distortion after an hour of veiwing. I replaced the lamp, but it sill has the probelm. Any idea what...

I hope this helps you but you might wanna look into some other posts too cause it goes farther then the lamps and color wheels. Basically it's a bad product and the consumer should be fixing it. But your problem seems to be the color wheel. Or just a good cleaning. We replaced the lamb in ours and still had a color problem. We're gonna do an exstensive cleaning and dusting of our unit and if it don't work. We're going straight to the manufactor. This is enough with this product! It's costly to repair and still don't have the quality picture it should. It's more then a simple fix and too costly for ppl to just fix and move on. For how old these products are this all should not be happening.

Color wheel bearing can make the noise you describe, and that will also cause color distortions.

Plasma TV color problem

Sometimes, poor picture quality occurs when having activated an A-VHS camera or camcorder connected and having connected another peripheral at the same time. In this case switch off one of the other peripherals. Also, The norcent has a known problem with progressive scan - when connected to a progressive scan source, it yields a distorted screen with dual images and messed up colors.
