What kind of cables are you using? I had poor picture quality until I upgraded to HDMI, the picture's great now.

Very poor picture. Looks like some picture setting way off. LIttle red in picture.

If you are using component cables to hookup to the tv check to see if one has come loose on either end. This will cause the color to be off.

Having trouble with the colors on my WIi, everything seems yellow and there is no red anywhere

I just wanted to add that I recently bought a WII and I have the exact same problem. I have a Samsung HD TV and I bought the additional HD cable that has the multiple jacks (i.e. green, blue etc.) I will post if I find a specific answer to the probem.

Maxent wierd colors

Artifacts can be seen on some screens that are trying to present high def color but cannot support the full dynamic color range. You will see this as banding or clustering in people's faces. Some brands handle this much better than others, and less expensive TVs can handle this rather poorly.
In your case, you may find that HD channels look worse than the regular signal channels.

Green hue on all inputs

Most likely there is a failure in the video processing. The flickering was from the failing components breaking down.

Your set can be serviced by an experienced tech who has spare boards and the facilities to service your set.

JVC HDTV Pictrure Distortion

Your TV needs to be calibrated. Rear projection TVs are very sensitive to movement. They have 3 color canons that need to be precisely aligned so that the colors overlay each other. They are like three projectors all aimed at the same screen.

If you were to enter the User Menu on the TV, you should find an alignment/calibration choice that will re-align the colors using some on-screen help.

If you are not able to resolve the situation on your own, a certified ISF Calibrationist should be called.

And, since you've bought this TV used, it should be cleaned by a professional (the canons, lenses, etc.)

Too much green color

Problem solved. I tried playing DVD and the TV picture was fine. So I double-checked cable wires from cable box - one of the wires was loose (obviously it was the red color input). After tightening, the TV picture is good as new.
