Hi all,
I have an IBM 5160 (256K) with dual floppy drives. I attempted to power it on today, the PSU powered up for a split second, there was a small pop and the magic smoke was released and the PSU fan stopped spinning. Now whenever I try to power it on nothing happens - The PSU fan does not spin.
I've been following the troubleshooting guide at http://www.minuszerodegrees.net/5150/problems/5150_known_problems_issues.htm and have removed the tantalum capacitors C56, C58 and C68 (C56 and C58 were clearly blown). I've just removed them and have left their slots empty without anything soldered in to their place - I assume this is correct?
I've tested for shorts on the motherboard's P8 and P9 rails and as far as I can tell they all look fine - No obvious shorts. This is leading me to believe that the PSU may be to blame. Is there a way to test the PSU standalone? This machine is dual floppy so I don't have an MFM drive to hand to act as load.
Thanks in advance!
