Are the reels physically spinning before/during the "no spin 1" error?  Is the error on the screen as soon as you turn the machine on (like it needs to be reset to try again), or is it spinning the reels but then giving you that error?

The reels do not spin they all get bumped like they are
being prepped but they do not spin at all

you have to operate the kickers out of the machine manually, the reason: so you see how they work in the machine. the bearing linkage resets the kickers so they can spin the reel. after the linkage is reset the back solenoid fires pushing the prong up into the star wheel on the reel itself, then the front solenoid fires and pushes that star wheel to spin the reel. make sure all actions are quick and easy, if not then it will cause an error.
even though the machine is in the tilt mode you should be able to enter into the test  mode. there are three buttons on the panel where the power on/off switch is located. a test button a reset button, and a cursor button.  press the test button, you will see inputs test on the display, press the cursor and advance to the optical test, you can now turn the reel and see if the 0 changes to a 1 and back, as the reel turns. this will test the optic and comm with the logic board. press the test button again, the output test should appear, using the cursor advance to the start solenoid test , do those then the stop test , this will test the two solenoids for there proper operation. press the test again and go to the reels diagnostic tests and start that test. this should tell you what works and what is broke.
