I have a Commodore 64 that, when turned on, gives a dark screen with what look like two stripes running vertically down the right hand side. I can't give a really good description of the picture since I'm using a crappy RF cable for an output, and I haven't yet made an RCA cable for it (Radioshack didn't have the part I needed!)

If there is anyone who could lead me in the right direction as far as what to check on the inside I would greatly appreciate it. I've poked around and nothing really looks like it blew up, so I'm clueless.

Thanks!
