try to play a DVD on your TV to determine if the problem is on TV or signal..

If the DVD plays same image you have bad t-con board,.,just replace it to fix the problem..

Did you already try it on another PC?
Try new VGA cable?
Otherwise you may have to open it up and look inside for failed components.

the cathode tubes are going out you need to replace them. there are three of them and they cost about 300 a piece. probably cheaper to replace the tv.

hope this helped

you will need to check the componant cables on the tv, usually if the pic looks green, and wont adjust, the red componant plug has worked its way out, check it on the tv, and on the box, hope this helps

internal codes are good, but when the is like what you post then a tech is what you need.it seems that one of the problem is the flyback transformer or the CRT cap.have a tech check you unit.

is it all redish pink or just a spot?

The problem with the set is that the blue gun has gone weak, and not emitting at par with red and green guns in your picture tube. Turn of the blue screen and get the grainy display on the screen (detach the cable) and enter into service mode to fine tune until you get a perfect or black and white grain pattern.

While it is true JVC tubes rarely fail, they can give trouble.
Another possible solution is bad screen / focus block......
Remove lower front grill panel and access board...Check for
smooth adjustment of RGB screen and focus.....let me know....T..
