Here you find general technical problems of Pinball2000 and their solutions.
CPU Fan Problems!!!!!
Processor Cooling Fan:
Although WMS used a ball bearings Fan, the Fans become
defect very very quick. Often after some weeks of operation they need
to be replaced. When replacing them remove that foil between cooler and
processor and use 'Thermoleitpaste/ thermal conducting paste' instead.
I even found a non working fan where the metal block had become so hot,
that the metal was now light green instead of the original color that came
from WMS dark green.
Be careful when you replace the powersupply or test it outside of the machine:
The system transformer of P2K transforms any foreign voltage to 110V for the CPU Powersupply, so the powersupply must be set to 110V when used in the machine. If it is set to 230V in the machine, the system will not start (in most cases). If you remove it for test and check outside the game, it must be set to your PLUG Voltage (e.g. Germany 230V). Always check the voltage when you bring back the computer case in your game. ATTENTION: Some operators in Germany replaced the Powersupply with a 230V only version and cabled the power away from the transformer directly to the plug. Buy a new PS for 110V and recable it to the Transformer to avoid any future confusion!
After poking underneath the playfield the game died he told me. "slam tilt switch stuck" What looked at first glance like a blown LM339 turned out to be a "slightly" more complicated:
The 50volts that stroke into the LM339 also blew the LS240 after it. And....................... It blew the ENTIRE DATABUS after that one plus some sideparts.
Total score: 11 blown LS240, 9 blown LS574, 4 blown LS138, 1 blown LS 245, 9 blown LM339, 1 blown ULN 2803.
Maybe it had been a good idea to switch the game off
It SURE is a good idea to warn people for it. Do not poke under the placfield! Do not gove the 50V coil voltage a chance to hit a cable of the switch matrix!

During the connection of headphones rob willemsen detected, that the
schematics concerning the speaker connector on amplifier board are wrong.
The picture of the 6-pin connector shows all speaker '-' on one side (pin
1,2,3) and all '+' on the other side. The drawings of the components
show a different thing, - pin 2 and 5 are swapped, that means 2 is '+'
and 5 is '-'. see schematics .
I checked it on the amplifier board and this is correct. When you look
inside the backbox WMS connected the '-' cables, all green/-- , to pin
1..3 and the '+' cables, all yellow/??, to the pins 4..6. The backbox speakers
are connected both the same 'green to -' and 'yellow to +'. This seems
to be wrong, but it is not. It seems to be a SW or HW problem of P2000-DCS
hardware that the audio-signal of left and right channel differs 180 degree
phase and that this problem was solved by putting the '-' of one speaker
to ground and the '+' of the other speaker.
Just had the sound on one of my SW die. It was static and then
nothing. Changed prism cards from my other one and it works fine.
I want to buy some
You should also see if the game passes the POST for the sound section
(it'll flag it in the error report if not) ... IF so, the DSP chip is okay
and you should look onwards from there for your fault. It's likely
a very simple fix - either a simple little opamp or a bad connection. If
no error report, then the DSP chip is likely okay, so suspect something
in the output, then ... Unfortunately, there also isn't anything *between*
the DSP and the output
When swapping RFM to SWE1 the sound might no longer work and you might see the message U109 error! This is no HW defect but a SW problem. You need the latest SWE1 sound software to be loaded and the the sound works fine again. See Game Swap pages for more information.
Static Sound Disturbance (German:Knistern):
A lot of Pinball2000 owners have problem with static sounds disturbing
the pinball 2000 great sound, especially in gameover mode. Tom Uban and
Martin Wiest finally found the solution for it. Read the infos below:
Well it is interesting that your removal of the cable tie on the cable
helped out the problem. The reason for the static (I am told) is that
there is cross talk in the signals driving the amplifier from the PRISM.
While there was an early change to add the inline resistors on some of
the signals, it appears that all of the boards I have seen (and which
you describe) have the resistor change. I guess that the change was made
fairly early and that very few of the old version PRISM boards made it
into the field. The second change (which I significantly easier to
make) which affects the static problem is to cut all of the tie-wraps
on the PRISM-amplifier cable and let the wires separate. This reduces
the cross talk and thus the static. I did this on my RFM, which was
having the static problem, and it has mostly gone away. Give it a try...
I removed all the cable ties of that cable in my Ep1 and all statics are dissapeared!!
Thanks a lot for your help.
I bought me a PUB card (didn't have and wanna have all). Tried to flash it in my PC but is was not recognised by the software!
I tried everything but no go! I removed all other cards from the computer but the AGP and the PUB still did not work!
At last I found that the BIOS setup was the solution!! The ISA MEMBLOCK is usually set to AUTO. I suppose that since the PUB does not use any IRQ, it does not tickle the ISA bus enough to get a memory block.
So I set the BIOS memblock manually to C800... and success!!

2 Lithium Batterys and some FLASH EPROM take care of saving data on a P2K machine:
1) Lithium Battery CR2032 on PC Motherboard (cheap, easy to swap) takes care of time & day which runs also when game is switched of. Replace it when you experience date problems.
2) Lithium Battery BR2335 on the PRISM Sandwhich Board. Not easy to swap, to only if you must. So far I am not shure, what problems exactly happen, when this battery gets empty. So far I have seen that they have still > 3,3 Volts!
