Paperboy Video Issue - Low Voltage on the Video PCB
I have a paperboy with some graphic glitches (vertical lines that are about 1" tall and across the screen). The game passes self test.
It has a switcher installed. It also has a AR3 that is plugged into the bottom of the video board.
The switcher is supplying power to the top board.
The switcher is outputting 5.1V.
On the video board, I am getting 3.5V at the test point.
I tried adjusting the AR3 +5 pot but it doesn't change the voltage.
Do I have a AR3 issue? Does the AR3 supply voltage to the bottom video board? Or does the video board get power from the switcher from the top board through the edge connector?
I am just a little confused as the thing has two powersupplies!
The LED on the VIDEO BOARD is OUT. The LED on the top main board is ON.
