Hi , i'm new here and looking for some help. I recently got an atari 5200 and it has a problem with the video. The video is clear and colorful but it kind of "pops" its visual and audible. When it makes the pop noise a line goes through the screen or it shifts up or down for a split second and goes back to normal. However it "pop" every few seconds. Without a cart in the screen is pretty much black but I can still hear and see the "pop". Also the controllers triggers dont work but I can handle that. I just dont know what to try to fix the video output. Im using the 5200 on a plasma with a direct coax adapter. The video looks fine except the "pops", lol.
