I have a 29" Matchline CRT which is 8 years old. When I connect to AV3 or AV4 (compatible 1080 component interfaces), and switch progressive scan to "on" mode on my DVD player, the whole video goes green. I can pull out the "b" (blue) component cable, and still the video is same green. But when I connect to AV1 and AV2 with the same component cable and turn on interlace on DVD player, the video is fine. I have tried different component cables too and it is not a faulty cable. Any help is appreciated. Also, support for this TV is very limited where I live.

Thank you for your replies,
