All right, new thread; the old one was resolved.

The Doctor Who Mini Playfield is not going up and down. The motor works. Tested it with a 9 volt battery. Replaced the fuse, just in case.

Errors No CW Movement and No CCW Movement are the only errors I'm receiving.

While attempting a playthrough, this is what happens when the ball goes into the Time Expander: instead of locking, it kicks it back out (and progresses the Time Expander Dialog).

People familiar with the Time Expander know that it goes like this:
1) 7th Doctor locks (Ace, you have to do it too)
2) Ace locks
Countdown to opening Time Expander

The balls NEVER actually lock the first playthrough, which is unusual because in the past when the Time Expander was not operating properly, it would still lock the ball and launch ball #2 and then #3. Now it just waits until the countdown to launch all the remaining balls onto the playfield from the reserve gutter.

After losing multi-ball, the balls WILL lock (but the unit will still not go up and down).

What should I check next?

Is there a way to test the glass switch? It was working as of a day ago, but I opened the machine to swap some bulbs and afterwards when I put it all back together is when the mini playfield stopped working. It clicks when you press it, but is there an actual test for it?

Glass switch is good. Moving on to others...

A 9 Volt battery can make the motor move at the connector point (the wire leads that go to the motor). Therefore the problem must be up the chain.

I reseated all the connectors that should be related to the Playfield according to the manual, but that did not help.

The connector that goes to the bi-directional board is good, so that is not the issue.

I turned the unit on with the board up and the red light is NOT lighting on the bi-directional board. Where does that lead us?

Okay, I have posted a pic of the bi-directional board; it looks good as far as I can tell.

ALSO, I just found a green wire (looks like a ground, mounted at the base of the backboard box) that is NOT attached at the other end. Anyone know where this goes?

Ignore the white stuff on my cabinet; old baking soda.

According to a really hard to see picture, that green wire MAY attach to the back of the left speaker.

LED 3 on the main board (back cabinet) is NOT lit. Don't know if this is helpful.

D19 is also off and D20 is blinking.

I ran the switch test for the glass switch and it registered.

The playfield will not move in the test mode (up or down). All other functions are registering normal.

I applied battery power at the Bi-Directional board OUT connector and the motor worked.

OLD: I did not apply battery power at the poles where the 4 wires go INTO the Bi-Directional board. I assume that there are 4 wires in due to Clockwise/CCW movement (each has a set of power but different polarity?). Do the leftmost poles control one direction while the rightmost poles control the opposite? SEE NEXT POST...

Okay, I ran power to the bi-directional board (9 volt battery) and the Red LED lit up, which it did NOT do when the machine was powered on, so that should mean the problem is further up, correct? The bi-directional board is working.

I have a DMM. Is J1 Coin Board Door Interface?

It MAY be a blown F111 fuse; I just did a continuity test on the fuse and got nothing (and I tried a separate 3 amp fuse and got continuity).

Okay, replaced the fuse and all is working!

The only thing I have never been able to get working is the First Doctor flasher behind the E-S-C-A-P-E targets; replaced bulbs (larger barrel bulb) and never figured where the fault rests. It's not a huge deal, but I doubt it has any relevance to the other issues I have been facing.

As an aside, I have had this machine since around 2000 (18 years) and have NEVER replaced a fuse.
