Hi all,
the transformer saga continues....
I got my I/O power board back from Beaky today and he has fixed various issues. He did a great job as always. Here's a list of what was repaired on the I/O power board:
Had a whole heap of transistors changed and most look like they have been running hot.
The reason for this is they have been changed with the wrong type of transistor. They have been replaced with IRF540 instead of IRL540,
The I C that controls these only runs on 5 volts which is not enough to switch the IRF540 on properly.
Plus there a several incorrect value fuses on the same board.
I put the board back in X-Files, so it is all complete bar a new transformer.
Also of note, this machine has a small transformer sitting up the back of the machine. My South Park machine doesn't have this. A small blue cable is running out of the main transformer and connects to this mini transformer. There are wires that run up the back and seem to connect to the fluoro. The blue cable on South Park is just sitting in the cabinet not connected to anything and no extra transformer in this machine.
For interest sake, I left the blue cable disconnected on X-Files and quickly fired it up. The machine sounds played and the DMD turned on like everything was working as normal. Then there was the usual crackle and smoke from the transformer. Turned everything straight off. Time to find out the cause of all problems before I purchase a new transformer for this machine.
Thanks,
Adam.
