Hey all i have a problem on a Frogger that has me stumped. I have a Hum bar on the monitor that wont go away. I have done a full cap kit and updated the power supply. I have also tapped the video signal and tested the monitor with a jamma game and the hum is gone. So i replaced the PCB thinking that was the problem and i still have that monitor hum. I am running out of ideas any input would be grateful. Thanks!
