Hello Folks. I recently have been having Driver board problems with my Williams Flash machine. I decided to purchase another Driver board from someone on Ebay with excellent feedback who claimed it worked 100%. The first day I had it hooked up my machine did something really strange after being on all day. The displays all started blinking double zeroes 00 and the coils were pulsing about once every 3 seconds. I turned the machine off and on a couple of times then everything went back to normal except it appeared to reset to factory settings as my Free Play went away and 5 balls went back to 3. I reset everything then played off and on all day yesterday without incident.

Today I turned on the machine and played several games then went outside for an hour. I came in and went up to play and noticed all of the displays were dead and only a few lights were lit up. You pressed the Start button and nothing would happen. I turned the machine off, waited about a half hour, turned it back on and everything was working again. the machine was still in Free Play and 5 ball play. I'm wondering if the Driver board I purchased could be defective and is causing this or is it a power supply capacitor issue or something. Such strange things happening. Any help would be greatly appreciated.

Always start by checking the power supply....especially if you have not checked it in some time. Sure, it could be driver board related, but you have to start somewhere. What is your experience level with electronics? Do you have the original driver board? What was wrong with that? How does it behave with the original board reinstall ed?

Did you read the Pinwiki and Clays guides?9

All DC voltages listed in the manual are good coming out of the power supply and all that are listed for the motherboard are good. 5 volts is present
