I got the game about 3 weeks ago. Game wouldn't boot up but the control panel would come on.so I replace some fuses and the big blue cap. Game boots up but control panel will not now and the game has no sound. The speakers are getting power because I can hear some humming when I turn them up. I had took the panel off to clean it and replace the ball. I put the new ball in and nothing worked. I reinstalled the old and still nothing. Does anyone know what I could try? Is it possible there in not enough power to support the panel and speakers?

rule 1, check power supplies. you need to check the voltages on the PCB. i have a feeling your ar2 might be dead. check the voltages first and let me know

I check the power supply board and the voltages are a bit high. 5 is right on 5. But the 10 is 12 and the 22 is 25.when I check it at the pcb pins I show 5 and I can't get anything else. The connector now that I have studied them more, seem to be missing pins here and there were it appears there should be one. I think I have a bad harness. Is there anything else I should try? I don't see anyway of lowering the voltage but maybe I am missing something. Any help is appreciated

well sounds like the power supply is just fine then.
Before you said the control panel came on? do you mean the cone buttons were blinking?

They looked completely normal. 1 player and the 2 player. Also the speakers have power because I can hear them hum as I turn them up

do you know if the monitor is working? you can check by looking at the back of the tube for any glowing in the base of the neck. or just turn up the flyback's "screen" brightness and see if you get the screen to go white.

I have an issue. I had no sounds and just silence. The control panel didn't work. I was advised to swap the lm 324 and pokey so I did. Now I get static to the speakers and still nothing to the control panel. In test mode the control panel works. I wiggle the hardness at the pcb and the static goes in and out. Could it be the harness or something else on the board. Please help
