Title: monitor chirp help please!
Post by: junkman on August 18, 2014, 08:19:49 AM

I have a datona USA arcade that I'm trying to fix. I plug it in and I can hear the game playing and I can con it up and the game plays but no monitor screen al black and I hear a chirp noise on the monitor chassis board. I'm not getting any neck glow on the tube. Is it that it may need a cap kit or is it the fly back what's making the noise and can someone point me in the right direction please. Thanks

The black part on the side of the fly back moves up and down the part that has the metal clip looks like a magnet is it suppose to so that?
