It really nothing more than static, if it were displaying anything at all, I'd mention it. Only thing it does when I turn it on is flicker and the static changes a little but can't tell anything other than that. All I know is these were in a junk pile and the guy said here, take em. I had a 5200 way back around 1990 that wouldn't do any thing but put up a green screen. Back then, it was easy to order a replacement board for about $45 and simply swap.
