I have a Battlezone that was working fine. I went outside for a while and came back in and the screen is blank. Marquee still lights up, but the +5V LED's are not lit up on the AVG or AUX board.
Here's what I've tried so far:
Tested voltages on the ar2-02 board and they all tested fine except for the +5V, it's showing 0.7V. I tested the wire from pin 6 of connector J7 since there is no header test pin for +5V.
Tested the voltage on the game pcb and it's also showing 0.7V at the edge connector and on the test lugs.
Disconnected the game boards and just ran the AR2-02 board. It's now showing +5.1V.
So the voltage regulator on the AR2 board seems to be working.
Not sure what would cause the voltage to drop so low when the game board is connected.
Thanks for any thoughts or suggestions!
