I have acquired an old Panasonic LCD Projector (Model- PT-LB20EA)

If I connect it to a laptop using the S-Video connectors then the picture is ok but without much quality.

If I use the RGB connector the picture quality is much better but GREEN!

Obviously I have changed the input accordingly and there is no colour adjustment available.

Any ideas please???

When you say green is this to say it has a green hue or are you saying the whole picture is green?

When you use component video you connect each of the color channels through 3 separate shielded wires, which are Red, Green and Blue.

If the red or blue are missing due to a bad connection, your color saturation or hue will be off or un-balanced.

Just like in the old days when a color gun would stop working on an old CRT color television set, the colors would be off or un-balanced.

Make sure the cables are not damaged in anyway.

Make sure the connectors on the Panasonic LCD Projector are not damaged or corroded.

If the problem is not fixable externally, this would mean the problem is a faulty component inside the Panasonic LCD Projector that needs to be checked or replaced.
