I also forgot to mention - Is the black plastic the opto boards mount
on warped at all?
My first one was slightly bent at the 75 switch end and it didn't work
- I got a new one from PBR.

Are you getting the errors when you turn the game on - or during the
switch test? Unless you activate those opto switches in the switch edge
tests (or in a game) - the tests that run when the game powers up will
still think they have not been activated.

Take the mini-playfield out and check with a digital camera that each
of the LED's is actually on.

Damn I forgot how many screws are in that playfield...

I get about 1.4V on the LED side between the common and each of the 5
led points on the board.

on the receiver side

I get 10-12V between the common and the each of the 5 points

EDGE TEST NOTHING HAPPENS WHAT SHOULD THE VOLTAGES TO THE LED BE I DONT

I have also suffered from a warped mounting on DW. I solved the problem
by inserting some spacers in to force the molding back into shape.

With the assembly removed from the playfield, remove the two circuit
boards from the molding, raise the playfeld and plug it in. Check the
emitters are working with a digital camera. Then shine a flashlight
onto the emitters, and check that they respond in switch edge test.
Then double check by positioning the emitter board over the receiver.
If both emitters and receivers are working then the problem can only be
with the molding, so reassemble and see what if blocking the light
beam.this is much easier now as it is not embedded in the playfield
assembly. When the molding is warped at the ends the interruptors break
the beam when they should be clear. Then reshape or replace the molding.

Pretty much any digital camera will show IR LEDs working. Try looking
at the emitter in a remote control through the camera. If you see it
light up, you should be ok.

Doesn't Radio Shack still sell there IR Sensor card? For a few bucks
it's a great tool. Just hold it in front of the LED and you can see if
it's working or not.

Nope, they discontinued it. You might find the odd one still in stock
at a store somewhere.

I have the dr. Who pinball machine and my mini-playfield is not working. It sounds like its trying to move it up whenever i turn on the machine but it does not move. Does anyone know what this problem could be, or what i should check for?
