Title: Bally S5500 won't reset LED Flashes no codes
Post by: wolfetrac on June 13, 2019, 05:41:39 PM
I just picked this non working machine up.  I have no history on it.  This is my first Bally Machine so I am new to this model. The power supply was bad so I replaced it.  I verified all correct voltages coming out of gray power supply box left plug.  The battery on the MPU has 3.6 volts.  The reset LED flashes steady. I tried a reset using J10 and pressing the test plus pseudo buttons described in some other posts.  Won't do anything.  Florescent lights come on.  Yellow light on door circuit board is lit.  I can manually cycle the hopper.  No coin compairitor light.  No buttons lit.  No reel spin.  No LCD display or codes.  All jumpers and switches on MPU are in correct positions.  No missing chips. 
I would like to know if this sounds like it just needs a reset, maybe with clear chips, an MPU board issue, a chip issue or something else?  I was told by someone that the machine will be totally dead when a complete reset is needed?  That does not sound correct to me?  I would think the display would at least display a code or something.  Any help would be greatly appreciated.   Richard

Sounds like your MPU is bad. Needs repair.  Send it to Alan. Badbaud is his  handle here.

Yes, I have a tester and all parts necessary to support that product.
