| Classic II ticking and fan spin - newbie here |

I'm a newbie and want to get started fixing my Classic II. When I turn it on, it clicks softly and I hear the fan spin up, but nothing else. The -12v and 5v are are not showing up, but I'm getting 12v on the positive. I have nothing on the display.
I’d appreciate any resources on getting started with this! |
