Question - in test the magnet divertor to the laser works, the mechanism moves, the coil will not fire in test or in game play. I have checked all the fuses - all good, I have checked the wiring - all good, I have replaced the coil - still does not work, the fire button works (the sound can be heard on the fire).

Just does not fire. The MPU has no battery acid damage that I can see but I know the main ROM chip is right below where the battery holder is - can't say it never had a leaking battery but it looks super clean.

The wiring is not pinching or binding it all looks good.

Any tips or any help would be appreciated.

Quoted from Thrillhouse:

Have you checked the plunger to make sure it moves freely in the coil sleeve? There is a test in the settings specifically for the laser, have you ran it with a ball in the cannon?

Yes I ran the Austin powers specific test for the laser even putting the ball in the cannon it would not fire, the plunger in the coil is free moving.

I kind of leaning toward a logic issue because the divertor does not que properly during game play but works in test. Just seems like some kind of mpu error. I don’t know why but everything looks good otherwise.

Still no luck to date - just won’t fire even though the fire button works.

I figured it may be a board issue - - I figured something had to be wrong with the logic that makes it fire.

Thanks -

Quoted from PinMonk:

Did you check the drive transistor that controls it? Sounds like it's blown. Test Q4 ("laser beam eject) on the board. You'll need a multimeter.
If you don't know how to test, read up on it here:

Quoted from PinMonk:

Do you have a multimeter to test the transistor? They're dead simple to test and relatively easy and cheap to replace.

Yes - I have all that I just hate doing board work just don’t want to damage a irreplaceable board, too hot burn a trace or something then I would be screwed. The board is not available anywhere.

I think I tested it right - looks like the transistor is bad. Used the pinwiki guide....

Thanks all -
