I had one where the flyback was the cause of it blowing. |

Good morning all, Well, this weekend was quite productive. I removed the bad 1-amp fuse and soldered in an inline fuse holder. To make the job easier, I constructed a simple wooden frame to attach the circuit board to. See pic below. With this setup I was able to easily get to the front and back of the circuit board without having to detach too many wires. I also made a 1-foot lead wire and attached it to the B1 pin. Tonight, when I re-install the monitor back into the chassis, I’ll be able to test and adjust the 120 VDC B+ voltage. Hopefully, I’ll have more good news tomorrow morning. Now I’m hoping to see this monitor light up. |

Bad news this Tuesday morning. After hooking the monitor back up into the chassis, and turning the power on, that mini fuse blew again, and still no power to the monitor. The B+ didn’t even show a reading at all. 0 VDC. It looks completely dead. It would be nice to have a flow chart like yotasuya posted, but start from power to the monitor/no power to the monitor. See pic below. (Just an example) I think this might be where I have to purchase and replace all the caps and flyback. There must be a more logical approach. Right? Also, aside from the monitor, I thought I’d try to see if the game would fire up again. I put two quarters in and pressed the two LED buttons. Nothing. It only happened that one time, where it sounded like the game was active. Sound was coming from the speakers and pressing the buttons was producing game sound like activity. I felt I was reaching a progress plateau. Don’t know what to think now. Any suggestions? Thanks. |
