STAR TREK ISSUES???

[ddstoys]

Well with the boys playing star trek we noticed that it gives out lots of extra ball but for no apparent reason.   I couldn't see them hit anything in particular and the extra ball light was not even lit half the time.

 Any ideas?????

have had something similar on both my star trek models, i went into programming, did a factory default. then went back in and turned on freeplay. it corrected itself. update the roms too.hope it helps.

Replay levels set to pay extra balls instead of credits

You were all really pissed and didn't notice when you hit the return to plunger shot?.

Um no 
It gave me 5 extra balls on my first ball, dont think I'm that good

"Same player shoots again" lit ?

Did the "ball in play" increase, or stay on the same ball ?

Interesting and very strange

I don't think the same player shoots again lit up but maybe it wasn't working
and I'm fairly sure the ball in play didn't increase, I could hear the sound for the extra ball each time it was awarded

Any AMI chip is questionable, about 50/50 that its ok. 5101 if old should be replaced & 6820/6821 usually can wear out even Motorola ones.

Now that sounds very strange. The only way a ball will be served again without incrementing the "ball in play" is if there was no score. Sounds like a ROM issue. Could be what John described - The CMOS 5101 - that's a possibility.

It sounds to me like a "one off" event. If it is doing it all the time - Check the 5 Volt line on the MPU and check the MPU is grounded.
