Hello everybody! This is my first post here, but I'll probably be coming back for more, seeing as how I collect old computers (I can't believe I didn't see this site before). Since I don't know what else to say, I'll just go straight to the point of this post.
I recently acquired an IBM 5155 in working condition in the US, and had it shipped to a family member's home, where I was able to test it out (it worked fine, and I was able to run PC-DOS on it with a floppy, and write programs in BASIC).
Seeing as I only have one permanent place where I can store these (my collection) at the moment (and it's in Europe), I had to bring it back with me.
Upon arrival back here in Europe, I had set the power supply switch to 230V, plugged it in, and turned it on. Unfortunately, and much to my display, it doesn't turn on properly at all. Instead, it comes on for about a second and shuts off again.
During that fraction of a second, I do manage to hear the CRT starting up, if I keep my ear near the back of the power supply. The PSU's fan turns on as well, and the two lights on the front of the 5 1/4 floppy drives flicker on, before it all shuts off. Turning the main power switch to "O" then "I" again produces the same result.
Two things have crossed my mind: Either it was damaged (or something slipped out, eg card/cable) during it's way back here, or the PSU doesn't agree with 220V. Since I don't have a transformer here, I cannot test my hypothesis that only the 220V part of the PSU is't working, and I unfortunately don't have the time to tinker (let alone take it apart) around with it at the moment. I'd just like to be able to try and get some vague idea of what the problem could be, I'm heavily leaning on a faulty PSU.
Thank you for your time.
