I thought maybe I would try again for some assistance in this thread and hope it gets more visibility:

Hello. I bought a TZ with a "Clock Is Broken." The clock had the OEM boards replaced (not sure of make...haven't taken it apart yet, but LEDs in a ring). It appears the A-16120 driver board has been replaced too (homepin.com).

I'm hoping someone can help me decide a direction based on symptoms:

- Credit dot error: Clock is broken 
- Does not run/move during startup or gameplay 
- Clock test entry it spins backwards only 
- Pressing the test buttons on the driver board it does run forward and backward.

I've tried the basic of reseating all connections. I thought perhaps the piano mod may have wiggled bottom of clock connex loose.

I know Twilight Zone clock repair threads are everywhere, I'm just hoping someone has had a similar issue and will chime in. I've read many, and I'm not sure whether it is driver or clock boards.

Thanks in advance for your help.

Hello. Anyone had this issue?

Please help me. I was putting side blades on my Twilight Zone and when I fired it back up to start a game, the upper left (piano shot) flipper stays energized. You have to start a game to get it to stay up, not just power on. Also in coil test all flipper functions work, but the hold test of the upper left does nothing.

By reading another thread I'm taking it is less likely a transistor issue, and more mechanical? I lean that way since I had the playfield gyrating to get the inner artwork on and I may have bumped something. Please see the photo below, but everything seems good to me.

Thanks!

Thanks. I will look to make sure the lamp socket is not close.

I got it behaving again. A little reseating of the opto board/blade/button play did it. Thanks for your insights!
