The LCD monitor turns on for just an instant of a second shortly after I switch on the G3 B&W. After that it remains in standby mode. A CRT will most certainly have a quicker response time when it comes to setting a mode. > Have you zapped the pram? Yes, like Kasey Smith told me to. And I additionally tried the Cmd-Opt-P-R keys right after switching on. I also tried resetting the NVRAM with Cmd-Opt-N-V keys. > Replaced the pram battery? I don't have a spare. I could use the one from the G4-AGP. (I first thought it was a GE, but it actually is an AGP.) Or the one from my G4-QS, although I would rather not use that one. > Clean the speaker; reseat its cable. I'll do so and report back. I could also use the speaker from the G4-AGP it the specs are the same. And I guess they are, since it looks identical to me. > Disconnect everything from both IDE buses. > Pull all the memory. > Try booting - you should hear error beeps etc. Will do. > Try cleaning the video card - it's contacts and slot.

Okay, this is too high for me. I'm not that much into Apple diagnostics. I never used the network boot mode either. Anyway, thanks for the help. I'll try to get it back to life as good as I can. I wouldn't be too happy either if I had to trash it. It's my first G3! I'll report back. Thanks, Andreas aka Mac User #330250
