rainbowing effect on rear projection TVs - Blu-ray Forum

callas01 · 12-03-2008, 03:34 PM

Hey everyone,

My my outside sales lady asked me about their rear projection tv and it is showing the picture and then around the image like a rainbowing effect of red and green. it jsut started and is always there she says, and more of an issue on the left side of the TV. This is a Misubishi, 48".?

Can this be fixed with a new bulb or is it dying or what??

Thanks Peeps.

It's not really a fixable problem.

Yeah, if YOUR eye can see it, then you will probably see it in any single-chip DLP design. If you want to have a DLP TV, then get an LED based TV. It is supposed to eliminate the “rainbow effect.” I had a problem seeing them too, until I viewed the model that I now own at Best Buy. Problem solved.

I don't always see it, but only when there is fast action on the screen or when there is a lot of contrast in the picture and I move my eyes around. Like other posters said, If you can see it now you will always see it. I am the only one in my family that sees it and I can live with it most of the time.

Same here...if i look at one corner of the screen then quickly shift to another side/corner, I can see it also. It doesn't seem very common though, most people don't notice it.

I guess for her and her BF, it surrounds the image. I guess like if you are looking at a dog on TV, there is the dog, and then around the dog is a red halo and a green halo

should be.

have her call tech support and see what they say. if its still under warranty i think it would fall under that category as being fixable by the manufacturer.

an exact model # for the tv would help us on the forums tremendously.

callas01 · 12-12-2008, 08:12 PM

yeah, she doesn't know what model number, and she thinks it about 5 yrs old. she said they tried the convergence, but said it would only move up and down not left or right.
