The rectifier, transistor / MOSFET, and controller IC maybe are defective.
Theres maybe more than one voltage.
Theres maybe more than one voltage.
The connectors look like 2 wires in and 4 wires out. Are two of the output pins unused? They might be for optional remove voltage sensing.That's what I was wondering... if it is possible to replace this with another power supply. The only problem here is that I wouldn't really have a clue what to ask for or to order. I am guessing that the transformer lable holds the clue. 240V AC .5 amp in and 24V DC 1.3 amps out. There are only 2 wires into this and 2 wires out. As for working it out, that is a bit beyond me. The other board that it plugs into has no values on the input side, other than "DC".
Lightening is a very strange critter. Our building got hit and it took out our phone system, which was on the network, and it took out the network cards in nearly every computer. My computer, which was nearest where the building was hit, lost the network card and the floppy drive and the diskette that was in the floppy drive (which was my boot floppy since the boot sector on the hard drive had gone bad years before). Everything else was fine and after replacing those three things I used that machine for several more years.Thank you everyone. I managed to find a guy who has worked on this model machine (and others) he is coming out in 2 days. He says he already has an alternate power supply and hopefully that will be it, if nothing else is damaged.
I really appreciate the input that I got. There is useful stuff here, if the tech doesn't get it done.
By the way. The lightning hit the power pole opposite my place and the workshop (a steel shed). It also jumped from my workshop to my neighbours patio (1.8 meters away). We lost a lot more than this board. The other stuff was easy to replace though and no one was hurt. My power meter didn't work either after the hit. Not even once the power was connected again. I reckon we got off lightly really.
