I just picked up a Turbografx from a thrift for $9.99, and hopefully some kind soul here can answer a question for me. I have all of the necessary hookups, but (unfortunately) don't have a game card to test it. My question is this: if I power on the system with no game inserted, should I be able to see anything on the screen. I'm trying to determine if the power/RF are working properly, but all I seem to get when I power it on is noise/snow. Should I get a black screen? A system logo? Something else? Thanks in advance for any help!
