I recently tried installing an LCD into my RFM and somewhat stupidly plugged the computer into the mains to test the monitor forgetting that the power supply is set to 110v, the fuse in the power supply blew immediately so i replaced it and the machine seemed to be working again however, on putting it all back together again and using the old crt for testing purposes i came across a new problem.

The power board shows a host of blown fuse errors but when i tested the fuses they are all intact. I don't know where to start in diagnosing the fault on this one!
I have added images of the errors as well a picture of the board whilst on.

As you can see there are a number of leds which are not lit. I tried turning on the machine without the computer too but the board leds still are not lit on those fuses.
I also fiddled with the cables and they all seem to be connected firmly.

I cant imagine that the power supply i blew in the computer can cause such an error can it?

Please help!

Thanks in advance...

I should also mention that when I put it back together again after fixing the power supply in the computer the game reverted to what I perceive as factory settings asking me to input region and pricing.
Additionally one of the many times I turned the machine on and off during this fault the 3 Martian inserts on either side of the play field were blinking but very slightly. Note: the machine has led’s.

The led’s remain off when the coin door is closed too. Also, the health Led does not turn on at all.
I didn’t test the fuses out of the machine, does that make a difference ?

I tested all the fuses with a meter and they were good.

Seeing as the fuses are showing bad wouldn’t that suggest the problem would be from transformer to power driver board?

Assuming the board itself isn’t damaged that is

Further diagnosis of machine shows:
Service credits button: working
Volume down: working
Volume up: not working
Enter: working
Start: not working
Action buttons left and right: working

I did notice that on occasion the machine would start to beep like in diagnosis and enter a game, tilt and generally go crazy all by itself.
I really don’t know how this relates to the power board.

I've posted additional pics: The roms seem ok but now i'm seeing a switch row shortened which wasn't there before.

I must have a short somewhere because the machine is constantly tilting and resetting and starting games by itself - see video:

Tried resetting the machine via the menu, upon reset it does the same thing.

Would this also affect the Power Driver Board or visa versa?

You think that would also account for the power driver board error?

Hi Rob,

I reseated the parallel cable and it would seem you were right about all the erratic behaviour. Game seems stable now but it still has the power driver board fuse problem.

Update:

Left the machine on for a while and it reset itself and acted erratic again.The volume down switch seems to be the only switch out of the four which sometimes works and sometimes doesn't. When you press volume down it may or may not register. Seems like it only sporadically gets power.
Interestingly I did hear a coil fire at one point while i had the door open (though that disabled the coils)

I will try find sourcing and installing another serial cable.

Meanwhile can anyone confirm if the Power Driver Board fuse array shows like the attached picture when the computer and serial cables are unplugged?
Seems thats a good place to start because that could confirm if the problem is the computer or elsewhere (reminder: i unplugged the computer and the power driver board still showed the same fuses blown even though they were not...see pic).It just feels like power is not being circulated around the playfield.

Switch tests show none on playfield are working, only volume, action buttons and credit controls seem to operate.

Update: I have now removed all cables to playfield and all connection to the computer. The motherboard remains the same only the following fuses show as ok: F108-F109-F110-F111-F112
All other fuses show as blown even though they are not

Update: I have also checked the serial cable with a multimeter and all pins seem to be good, don’t think it’s the cable!

Can anyone who has a pinball 2000 please remove the serial port from the computer and have a look at the Power Driver Board and let me know what fuses are lit (a pic would be great) that will immediately tell me whether it’s a Power Board issue or not.

That would be much appreciated.

Rob,
I’d imagine that when the computer is disconnected the fuses should still show as functioning if they are ok, is that correct?

So it may still be the PC?
Makes more sense to be the PC if that’s where the power supply blew

Maybe I should look into a nucore system and see how I go from there, what do you think?

Any idea where I can find the roms? Apparently you need the original nucore Roms but I can’t seem to find them. Everything else I have found.

Solved:
Installed a Nucore system and everything is working fine.

FYI for anyone who is showing blown fuses on Pin2k even though they aren't actually broken Borygard is correct:- If there is no communication between the computer and the Power Board, the fuse reporting, and the HV fuse LEDs will not function.

Thanks all
