Pioneer bdp 51fd picture color is green

check screen options. sometimes you can change the primary color's intensities(it looks stupid at 100% for all). You might have red a little low making yellow and blue show up greenish on the screen.

I have a mitsubishi vs-60111 and the color is a greenish, grayish color i checked the bulbs and they are working the red is bright the greenseems to be good and the blue is bright ?

color problems are the hardest to diagnose, especially if one cant see the picture, but depending on how many hours the TV has bin in opp oration, the first suspicion is the red CRT, the proportions of red green and blue are critical, and the red is the most demanding therefore the read is the most intense color and will be the first to fade, you cannot depend on just viewing the CRT to diagnose this problem, they go dim over time, if you can try to turn up the brightness of the red CRT, some older models may still have a manual control , if not there will be adjustments that can be made via soft-where setup, let me know how you fair with that, do not look directly into the CRT,,,,very bright and not good for the eyes, also there may be upwards of 30 to 40 thousand volts at the CRT anode lead, be very careful

Projection is messing up. Too much red and blue color.

A CRT projector requires Convergence and Color balance adjustments from time to time. These settings can drift. What you are seeing is a lack of Green color intensity. Do you see some pink in the 'whites'?
The Green CRT surface also burns off faster than the Red and Blue leaving behind the same appearance. As long as your Green CRT is not too burned by gaming or watching Golf and football, a local tv tech will be able to dial it in for you.

This is an LCD rear screen projection TV. There is a Red, Green and Blue LCD pallet that is mounted on what they call an X-cube. If all you are getting is Red and green then something happened to the blue pallet. Either the Ribbon connector came off or is loose or something worse. How hard did you mover it?
Another thought. How is it hooked up. If component then this may be the issue as component video connections are Red, Green and Blue. Just a thought.
Let me know.

Same problem w yellow on viewsonic pj550

Yellow is the mixture of 100% red and 100% green. what you may have here is a blue LCD failure in the machine. Try this to check. Open up PAINT and double click one of the colors on the bottom. now click add custom color. then in the RGB section put 0 for red 0 for green and 255 for blue. ok out of everything and fill the background w/ the blue. it should be a VERY intense blue, if its white or or kinda blue, you have an LCD issue

After a few minutes the color goes to intense red and green

My tv didn't turn green, but the red separated significantly. It started off happening after a few minutes of being on (I suppose the defective part was "warming up"), then it got to where it was like that immediately upon turning the tv on. In my case, I had to pay a tv repair man $350 for a new part. There are 2 microcircuits that control the color alignment--one that controls the red only, and the other controlls the other 2 colors, blue and green I believe. Maybe your part is the blue/green controller, mine was red. The repair man said these parts fail so rarely they don't stock the part. The cost of repair may be different for a different part, but either way you have to choose if it's worth that cost to you. If you get rid of it, I'll buy your tv stand ;-), I bought mine from a friend and didn't get the stand in the deal.
