I have a hitachi 50vf820 with green tint to it


Its a DLP type set that uses a lamp for a light source.

With the color turned to zero stand back and examine the image.

If mostly all green or areas are green you may have a issue with the optical light engine--either damaged inside from the heat of the lamp or the portion that processes red, green, and blue information bad.

you can fix the dimmed look to the tv by purchasing a new ballast for the DLP bulb.

The spots are non-repairable as they are in the light engine assembly and those are nearly $500-$600 and very labor intense to install.

Hope this helps. Click the hyperlink above to buy the ballast.

Hi I have a Hitachi 50v720 and I just replaced the bulb with the Phillips UX21517 bulb. When I turned the tv back on the picture worked fine except everything has a yellow tint.


I don't know if this set is a DLP or not, if it is, it could be your light engine. Not good, mine had a yellow halo about 2in thick in the middle of the screen. Light engine had to be replaced. Hope this is helpful. GOOD LUCK!
