Hi everyone, I am in need of some help to try to see if I can salvage a really good (and expensive to replace) machine that we were using daily.
The big transformer in the center looks iffy. also, the chip in the center is an item that tends to fail. Sk8085 available on eBay from sellers in China for $5 to $10 with shipping.Ah OK, thanks I'll have to get to the electronics shop tomorrow. I thought that the glass was just an insulator. House fuses can be either way...
Yes it is just glue on that. Yesterday I managed to get another fuse (bought a pkt of 10), and it blew again. My feeling is that the transformer has probably gone. I am also guessing that it has to be de-soldered from the board before I can test it. I think that the logical thing would also be to NOT connect this board to the next one so that I isolate that probability of some component in the next board causing it.Either it got hot or it was trimmed at the factory and a low-quality epoxy was dabbed on to keep it in position.
That "input board" is a power-supply. It's way past time to declare a 'quick fix.'Hi everyone, I am in need of some help to try to see if I can salvage a really good (and expensive to replace) machine that we were using daily.
We got struck by lightning last week. It seems that every appliance that was plugged in (some switched on, but not all) have bitten the dust. In nearly every instance it has been the power supply to each appliance or machine.
Most are replaceable and some already have been, but our large laminator is old and doesn't work. It doesn't have a separate power supply.
We found a 240V 2A fuse on the input board (which I am assuming is a power supply). I couldn't find a matching fuse, so I drilled out the ends and used a 240V 2A wire from another fuse. I carefully soldered the wire in and replaced the fuse, BANG. It lit up like a flash light. That tells me that something else has failed. I am wondering what the most likely component to fail would be? The manufacturer is in the USA, this is a really old model and I am in Australia. I am wondering if there is a quick fix. Any ideas? see photo. Please note I am not an electronics person, I can tell a transformer from a resistor and capacitor, but I don't know electronics. As I used to wire up amplifiers I am sure that replacing components would be easy for me. Diagnosing the fault is really beyond me. I do have a multimeter (or two).
