So I'm getting pretty excited. My first pinball machine (Dr. Who) has been refurbished and is ready for delivery. Im going to their shop Saturday to give it a once-over and wanted to ask the forum for a checklist of sorts. What details should I give close scrutiny to? I'm a novice pinballer but pretty astute with computers and such. Thanks!

Congrats. Test every single switch and coil with them. (There are diagnostics/tests they can run off the machine)Make sure they fix any issues you find. If they say don’t worry it’s an easy fix, then get them to do it for you.

I’d also recommend playing a bunch of games on it to see if anything else is out of whack but it almost needs to be levelled before you can do that not sure if they would entertain that.

Look over hard to clean areas. Are they clean or dirty. Look at the boards in the head, do they look new, or serviced with the right tools or parts, or do the boards look hacked or battery damage on cpu ?

If you can, bring a friend that knows pinball with for another opinion.

Don't get caught up in having to drag that first game home no matter what. Make your first pinball machine a great experience. You'll be glad you did.

Great, make them run through the diagnostic first. Good advice. The last time I checked in on it it was giving a missing ball error message. I know the elevator on this machine can be wonky. Thanks!

Good stuff. I was going to make them open it up and check everything out (with my mini led flashlight). The machine was on a route so looking in the hard to clean areas is another good idea. Thanks!

Make sure the pf moves smoothly up and down through all 3 positions.

Make sure the upper flipper can cleanly shoot the ramp.

Make sure all 5 dalek armor targets / optos are working.

Make sure the display is crisp and clear, no missing lines or columns, no degassing in progress.

Make sure the boards have no weird hacks.

Make sure there is no corrosion damage to the mpu. Even slight corrosion can make the mpu break down.

Make sure battery holder is removed from mpu and either placed remotely, or replaced with nvram.

Do a switch test to make sure all switches activate correctly, and a solenoid test too.

Play some games and hit both flippers at the same time a bunch to test for the Williams reset issue, if the game has it then the power board will need new caps, rectifiers, and lm323. If the game has a little daughter board between the power board and you, then it probably has the issue but it's being corrected by the daughter board. In that case it will need a power board restore soon.

Warning. Keep hands away from mini play field.

Congrats, awesome game, a long term keeper!

Aside from checking all switches (lots of optos), flashers you want to make sure the Mini-Playfield is working well. Also, the trapdoor off the left side of the big ramp. WPC games have issues with resets and there's well documented repairs for that.

Mini-Playfield: lots to go wrong with that. In test, you should be able to drive it up and down. All the mushroom buttons work. Dalek Flaps engage and release (inside the chutes of the MPF). Cracked plastic dome on the MPF. Locks/lock ejects.

Playfield: Slings, playfield wear on ball drop, playfield wear coming out of the mini-playfield. Does it have lightning flippers or regular 3" bats (stock is lightning flips).

Ramps: Especially the front edge of the right ramp. Who-Mobile covers.

Topper: Plastic dome over the top and mini-Dalek in the dome w/eye stalk. These are unobtainum and rarely are on the market. Possibly there s a moving Dalek motor in the topper. Test 15 will allow you to put it through the paces.

Cab: the ink fades, especially the red.

Sorry for a pedestrian question, but What would a board with hacks look like compared to an original?

Burn marks, solder blobs, jumper wires glomed on. Bent components, wires soldered to board instead of on a connector, two or more connectors on one spot where there should be only one connector. etc. etc.

Yeah the cab has been repaired but the side decals are faded. The Dalek topper seems to be intact, and the mini pf is working.
