I have a high resolution TV monitor that I bought in '88. It is a JVC model AV 2637S. The monitor has been a great investment. But I am about to upgrade to a widescreen. But I would like to keep the JVC. My problem is the JVC has developed a tendency to shade every light color in green. Basically the scenes are a wash in the color of lime green (unless the picture is overwhelmed with another color). I was wondering if my tube has gone south or can I have a technician fix this? It would be a huge saving if I could retain the TV. I have a very large VHS collection most of which were recorded off of cable.
