    I just bought a used Mac Mini and upgraded it (professionally) to 2GB. It came with a cheap Westinghouse monitor. However, when I turn it on, the monitor says "No Signal Input" and goes to sleep. I turn my computer off and on (with the power switch as I can't see what I'm doing), the picture has come back once (picture is fine) but that's it. When I restarted, it went back to "No Signal Input". I've used a DVI cable, and a DVI to VGA adapter and a VGA cable (the monitor takes both). I have gotten it to work once with each cable. What gives?

    EDIT: I tried another monitor with the same result. :eek:

    Also, when I was able to make it work, it would not let me adjust the volume. In Preferences>Sound, the sliders were grayed out. When I put in a CD or attempted to play something from iTunes, it wouldn't play it. The time bar stayed at 0:00 (as I had no sound anyway). It worked before with the same speakers I'm using plugged into the headphone jack. ???

    First I would try another monitor. If that fails then it's likely the mini.

    Thanks Jessica, but I only have the one monitor. (I edited that into my original post)

    To see what may be going on, I would go to System Profiler (About This Mac), Hardware, Graphics/Displays and look under Display. See if your Mini is recognizing your monitor. Check that your monitor is specified, Online=yes, and see what the recognized resolution is.

    As far as sound, go to System Preferences and select Sound. Check that Input and Output connection types are correct, and that input and output volume sliding bars are somewhere in the middle.

    I'd definitely try another monitor. I bought a used G4 mini off of craigslist a few weeks ago and it didn't like my Acer 20" LCD at all.

    It liked my plasma TV, though. I've since moved on to an Intel mini :).

    Good luck!

    All of that is grayed out under Sound. I have no options to change. I can look at input/output but there is nothing there. Thanks!

    Sounds like there are some issues with the logic board.

    If you try another monitor, external speakers, and it still doesn't work then its the Mini.

    If its the Mini try unplugging it for half an hour and restart from scratch with new monitor and external speakers. If it fails then there is something wrong... :(
