I've got a model 1 Genesis that I can't get to work. All I get from it is a black screen on the TV. It doesn't matter if I use an RF switch or the composite cords. I know its getting power because the power LED comes on, and the TV is detecting a signal coming from the A/V cord. I also checked the plug and it is working. I went through all the solder points on the board and cleaned up a couple that were iffy, but it didn't help anything. There's also no obviously bad components on the board.
Any suggestions?
