I recently picked up a cab with a 27" D9200. I'm pretty sure it had been using VGA all it's prior life (Madden Football PC based game). The seller said he hooked a laptop up to it and it had a great picture.
I just finished installing a JAMMA harness and swapped the monitor output 'plug' to the CGA position. I got a 'no signal' box, then realized that I had connected the composite sync to the chassis vertical sync pin. I fixed my harness and was rewarded with an awesome picture.
The problem is that there's a high speed clicking sound from the flyback area of the chassis. What's really odd is that the sound wasn't present when I just had the 'no signal' box on the screen. I see no arcing when looking at the chassis, flyback or anode cap.
I'm planning on using this cabinet for a party this Sunday, and I'm worried about the sound. I left it on for about 5 minutes and made several screen position adjustments via the on screen menu with no issues other than the clicking. The cabinet doesn't have a back door right now, and I'm wondering if I'd even hear it with one.
I made a video of the behaviour, and note that the camera was right next to the chassis so it may sound a bit louder than if you're a couple feet away. Sorry for the wrong orientation of the phone's camera!
