Upon startup, the game powers-up but ends its' startup sequence quickly. Watching the MPU A4 board when powering-on, the LED flashes 4x but not the 7x indicated in the manual. The MPU board is very new (replaced just before i bought the game 15 months ago.)

Any advice on what to start checking?

Just in case it's related, the third flipper had been double-tapping / shotgunning recently. I just replaced the coil and the above problem appeared at my first startup post-coil replacement.

Thanks in advance for your advice!

Pinwiki suggests check U11 if you're not getting past the fourth flash: http://www.pinwiki.com/wiki/index.php?title=Bally/Stern#Fourth_and_Fifth_flashes

so... REALLY dumb question... but what does "check" mean? unplug / plug back in ? look for a burn or short or something?

Awesome resource there, by the way... never ran across that one before! thanks for sharing!

sorry to be a pest...just not sure what exactly i should check here. if an IC is bad... can i replace just that on the MPU? is there a fuse someplace i should be looking for?

Appreciate any guidance.

I would try swapping the ICs from U11 to U10 ( they are the same ) just to see if you get a fifth flash.

Fourth Flash:
The Fakers Guide: no fourth flash means U10 (6821 PIA) is bad.

Fifth Flash:
The Fakers Guide: no fifth flash means U11 (6821 PIA) is bad.
