OMG. If it is a rear projection LCD then you have a bad light engine. Any good repair shop will repair for $200-250.
If its an older 3 tube projection then you have contaminated coolant in one or 2 of the picture tubes. Just drain out the fluid and replace with new. Should be able to do in 15 minutes. total cost $45.

SOURCE: greenish yellowish tint on the tv

I have been advised that the color/light engine of the TV fails often and will typically create a green tint on this unit. I have one on order to get a replacement installed. BTW, it is not "user serviceable" and (for me) will require moving the TV to the repair shop for the change-out.

SOURCE: blue tint on rear projection tv

If this is a crts model , then one of the crts had blown, if it is a lamp rear projection, then it is a fault on the video circuit.

SOURCE: Rear projection HD Hitachi Ultravision always has greenish tint

This is what you're going to do, Turn on the Tv and go to the service manual, if the green tint is still there, you have a defective dmd board, but if it's no there, then you have an issue with your video board

I replaced the lamp on my Sony KF-60XBR800. Now the picture is greenish and yellowish. I was told I might have touched/moved the purity ring/s. Where are they located?


Sony TVs has an Optical Block issue. If there is an issue with the optical block, then there will be green, blue patches or tint on the TV display. Try resetting the TV to the factory settings and try Power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue still persists, then TV may require service. You can contact the Customer relations team and check for the available options. Sony had repaired free of cost for such issues. Hence, contact the customer relations.

Tint on television stays a greenish color.

Tubes are probably dirty. Very expensive fix. Unless it has a warranty or is recently new, look for a local cheap one or one with a smashed screen of the same size. Easy to change the screens out and is very cost effective.
