So, I think my PM G4 finally died. I had been using it as a media annex (not center) in my living room since my 22" Apple Cinema Display still works fine. Now I'm stuck with a 22" monitor that can't be connected to anything. I've been looking into what can be done. Based on an Apple Support Document, there is a M8661LL/A part called "Apple DVI to ADC Adapter" that I think will do the trick. If I get it, I should be able to hook my PowerBook G4 up to it, right? If so, the next task is to find the sucker. Searching online for the part number didn't yield much, but I did find a nearly identical product number, the M8661LL/B on Amazon for $90 (yikes!!). The only difference is the suffix letter. But I don't know enough about this to really know if it'd work. Advice on what to do with this monitor would be appreciated!
