Question about Toshiba Televison & Video

I have a 57H84 toshiba. My screen is dark. You can only watch it if he screen had been broken but was replaced. Except for the third screen which we did not realize there was. Is this a screen issue or something else?

Outer if 3 screens is just protective and inner two are critical----they focus and direct the light from the picture tubes to the front of the set---yes if missing one of the two inner (usually taped together) it will not be bright or look right and both have a inner and outer side to them.

I just bought a used 57h84 and the pic is not real clear and dark and sometimes it seems to be alittle blue could it be the bulbs


If your TV looks 3D, warped, or distorted it likely has a convergenge problem. If however it just looks dull, washed out, redish, or if it looks like objects on the screen have halos the fluid in the lens has soured. You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!
