So I bought a Performa 580CD on eBay recently. It was in full working condition when it was shipped, but it was badly damaged during shipping (see attached photos). The front of the case is completely broken away from the rear. Looks like it was thrown from the back of a truck. Currently seeking a refund.
Naturally, it no longer works. When trying to power it on, nothing comes on--no power light on the front panel, no hard drive spinning up, no display, no sound. No static on the CRT screen. The only thing I think I hear is a faint sound for about half a second that sounds like an old CRT TV starting to come on, but quieter.
The CRT, which is supposed to be mounted to the front of the case, is completely broken free and basically hanging with only friction and the internal microphone wire keeping the front of the case from totally falling off and the CRT from falling out.
I don't actually see any obvious damage to the internal components, but something is obviously broken. I don't know how to go about testing the boards or parts to see what's junk and what isn't. I don't have access to a known good machine and I don't have any known good spare parts to use in troubleshooting. I do have some of the typical benchtop test equipment (digital multimeter, LC meter, digital oscilloscope, regulated DC power supply, audio signal generator, isolation transformer).
I don't want to just toss it or break it down for parts. I'd like to find a new case and then get it working again, but as I said I'm at a loss as far as troubleshooting goes, especially with the current damaged physical state of the machine.
Ideas?
