Hey Guys,

I've got a Gottlieb Touchdown that has a couple issues that I need to hammer out.

I've got a silk screen that is in horrible shape and I'm trying to figure out how to save it, but that is not my main issues.

None of the digital score boards work, and I would love to get them fixed. Anyone have a good idea for where I should start looking for the source of the problem?

Thanks

Are both LED lights on the power supply? I would start at the source (power supply) and work down the chain...

As Ken stated, the Pinwiki index on System 80* is a great reference...

Both LEDs on the PCB behind the score board are on and solid. I haven't looked through that guide completely yet so I need to do more troubleshooting first.
 
Hey Guys

I checked the AR02 board and even though the LEDs are on, I checked the J3 connector using pin 5 as the ground I got the following results:

Pin 1: 00.2 volts
Pin 3: 00.2 volts
Pin 6: 05.6 volts
Pin 7: 05.6 volts

Any help would be great!

Thanks
