It sounds similar to CRT caps discharge but I don't see what you mean on the lobo, so I assume you must mean the PSU? (otherwise after the last 10 minutes I'm very lucky to be alive lol).
The one working thing (honestly I'm more glad I got the monitor than the LC - I threw one out about 15 years ago... regretted that until yesterday):
Sorry for the blur and perennial rotation. The closeup of the board should show what I mean about the gunk or whatever it is.
Actually... should I clean the board first? That isn't to say I won't clean it anyway, but is it possible that 1) a cleaning and(/or?) recap will have some impact; 2) can I turn the power supply on disconnected from the mobo? I've asked this about my Compaq, but can I see if it works at all? Can't clicking also be a symptom of mobo failure ('we' have talked about this re: the PB 3400c - obviously very different architecture though)?
