Check the flipper button switch, if that don't do it follow the path untill you find the problem. Use a digital multimeter to check the voltage at each point etc...

I had this problem when I got my SW and it was a loose flipper wire and it just had to be soldered back on

BTW you wanna sell me your TSPP??? LOL JK

+1,If you dont find a loose wire then check the driver board connections.
Do you have the manual?

Check the driver board connections in the backbox

Hang in there labguy. Im sure its something simple we just gotta track it down. Give those connectors a wiggle and keep looking for loose or broken wires. I find it odd that both flippers are dead so I really think theres a break in the chain.....or something silly like that.

Do you know how to use the Portals diagnostics? Go into the solenoid tests and see if the flippers work in test mode. Report back.

Oh and, if you didn't know, you will have to enable the high voltage for those tests to work correctly. There are two white interlock switches to the left when you open the coin door. The top one can be pulled out and locked for the HV.

As Cliffy mentioned run it thru the solenoid tests - if they check out then run it thru the switch edges test and press flipper button to make sure the switches are also working.

If one of those doesn't check out then you can work from there.

If the upper playfield is working then I can assume the flipper button works - but I dont have a TSPP so Im not sure how they have that built could be two switches etc.

keep us posted

Just take the glass off and use your finger for the right flipper only. Then when you find the problem put the glass back on and play with the flippers.

Any progress???

Find the repair manual thread and start reading. The link above has some good documentation, but not factory repair info, (not on that page, but maybe in a link there).

Follow these steps first like cliffy has mentioned

Do the flipper buttons work fine in diagnostics

So only one flipper doesnt work?

Sorry,I forgot Stern has 2 lugs and not 3

pinmike, TSPP is a Stern/Sega Whitestar game. Similar to DE, there are only two lugs on the coils and only one winding. So he's going to need to troubleshoot similar to the DE/Sega methods rather than WMS.

Let's recap this:

-It sounds like the flipper switches work in diagnostics mode, so the switches are good.
-You stated that the lower right and middle right flipper do not work during the tests in diagnostics, right?
-The right upper playfield flipper works, right?

When you say you swapped the fuses, you swapped them with known good fuses?

If nobody comes up with more info tonight, I'll try and look into this more tomorrow.

LabGuy, do you have a multimeter with a diode testing function on it?

Okay, first things first, Stern does provide tech support for their games, even in situations like this when you buy a used game from someone. So if all else fails, you can call them at 800-542-5377. Also, the flipper information is on page 106 of your manual.

First, let's verify that you are getting 50v to the two flippers that aren't working. Lift the playfield up, leave the coin door open, and pull out on the white upper coin door power switch located on the lower left of the coin door inside the cabinet. This will enable power to the coils.

Next, find the red-yellow wire that goes into the playfield fuse block for the upper right flipper. Put your meter on DC voltage mode, put the black lead on a ground braid in the cabinet and the red lead on the fuse block where this red-yellow wire is attached. You'll probably read around 65+ volts. Let us know if you get a voltage reading.
