So I recently got my Quadra 605 from eBay,
See? There it is.
It is having issues power on. What I did first(of course) is hit the power switch, it starts up the hard drive, makes the startup sound, and does nothing from there on. Nothing appears on the screen, hard drive makes no noises(indicating is being read from). I then flip the switch off for 1 second then flip it back on, makes startup sound, starts hard drive, etc. Then it starts to boot up(screen comes up, smiley Mac, hard drive making noises).
I did notice that when I picked it up, something was rattling around inside the case. So I open it up to see what it is. It happens to be one of the surface mount capacitors. The pins were fine, and the component didn't look damaged. I eventually found the location of where it came off (C161, near expansion port). So I soldered it back on, and it still has the same issues powering up. What could be the problem???
