Just picked up a decent/clean TW. The game plays however I have one remaining issue. I saw another post with the same issue in the club but didn’t see a response.

My drop targets reset at the start of a ball, they score when hit however they don’t reset when either the 3 or 5 banks have been completed. Wiring looks good, reflowed many connections, fixed a couple broken wires. Diodes are all good too. Not sure where to go next. Any help is appreciated. Thanks!

Cleaned the sliders and contacts and making progress. At this point I can get the bank of 5 to reset by slightly putting pressure/bending on a corner of the assembly from underneath. The bank of 3 is about 70% on resets. Does this mean contact adjustments to fine tune? If so, any tips on figuring out which contact is the culprit?

Not seeing anything obvious and all drops score, all wiring is intact and correct. Slider boards are in surprisingly good shape. I’ll keep messing with them, must be just a slight adjustment on one or more of the contacts.

Last issue I have with this machine is the display. I have a couple burnt resistors on the master display board which I’ll replace. Master display board has flickering displays. Per some other posts, I’m thinking IC11 needs to be replaced. Pulling off and reseating connectors corrects this issue short term but it always returns. Anyone have any additional suggestions?

Thanks Bax1 and @someotherguy!

Reflowed the header pins and the display issue is resolved however a new problem has come up. The game will boot, GI lights come on but on the master display and P1 displays there’s a rolling counter. The game just keeps cycling through this. If I boot with the test switch in manual, the game does nothing. Pressing the diagnostic switch on the MPU yields both LED’s flashing twice then going off. Thoughts?

I’ve tried both with door opened and closed. Rom sockets look original so I’ll replace them and report back. Thanks

ROM sockets were in good shape, replaced anyway. No change.

The two 4-pin connectors were in the right spots as they’re keyed.

Still no progress

I’ve worked on several early wms solid state games and have found quite the opposite of what was quoted from pinwiki and have had much success relying upon the mpu flashes to guide me in the right direction for repairs. I’ve never seen the behavior this game is displaying. I’ve ruled out all the obvious possible causes including some of the suggestions from this forum. I picked this machine up from a friend who said it worked prior to the battery holder breaking and that he had a “repair guy” install a new holder which didn’t fix the game (no corrosion on board).
