Yesterday afternoon I was working on commissioning my old Apple IIc. After a few years of total disuse I decided to clean it using a degrea degreaator product. To do this I completely disassembled all the pieces of plastic so as not to wet the boards.
Unfortunately, a couple of minutes after the monitor was turned on, it happened that a polyester capacitor in the power supply part exploded. I found electrical diagrams about the monitor. My first question is this: the electrical schemes refer to an A2M4090 model monitor, but I live in Italy and for obvious reasons my monitor is a European model whose acronym is A2M4090Z. Are there substantial differences between the two models or the electrical schemes of the first are fine for the second?
The polyester capacitor exploded in the manual corresponds to the C772.
Can the fact that it exploded correspond to an age-related problem? Did the same thing happen to any of you?
