I received my first 2600 the other day. It came with a bunch of problems, most of which I have fixed. The RF switch was busted ( I replaced with a coaxial converter) and the power jack needed to be re soldered. My new problem is with the graphics. The system runs fine for a couple of minuets and then the blacks turn into this orange and it looks pretty bad. See attached picture for what I mean. Is there anyway to fix this?
