The six pin plug is the video signal from the PCB. RGB sync, and ground. Check the fuses on your monitor. |

Testing the 6 pin plug is a lot like testing an HDMI cable.. you would be testing red/green/blue/video signal.. and they would be jumping around.. I'd be surprised if your meter could lock on an voltages in the first place. Your real issue is how to test the monitor.. It's going to be best to test it on the bench.. There are troubleshooting guides for it too.. Check to make sure you didn't blow any fuses again.. To get sound with centipede - you need to coin up - then the player 1 button will light.. then start .. should get sound. At that point - you should focus on the monitor. Obviously that fried chip needs help.. There is also a voltage test called B+ Its the first thing to check Glad to see you made progress! |

Thanks guys for all the encouragement and great advice! :cheers: Now it's monitor to bench time. I'll let you know the status of the fuse and other parts once I take a good look at everything. First with the obvious fried chip and I'll see what I can find out on that voltage B+ test. Thanks again! Have a great day. |

Good morning all, Well, on to phase two. I removed the monitor from the chassis and it’s now on my work bench. The fuse tested out to be good. That bad component that we looked at awhile back, no longer looks like a chip to me. I thought it was going to be a 10 or 12 pin chip that I could easily remove and replace if need be. The component looks like it’s made up of a couple coils soldered directly to the circuit board. I took another picture of it from a different angle. See below. Additionally, I watched a couple videos of testing the B+ voltage. One video was saying that the voltage they we’re looking for was 208 VDC, while another video was looking for a 108 VDC. Does anyone know the exact voltage for my Hitachi monitor? This monitor is type 37OESB22, Model: 13” COL GAM MNT. I couldn’t find any video specifically for the Hitachi. Also, when I’m test for this B+ voltage, can I just make a patch cable to supply the initial 120 VAC to the 3 prong plug? I’m going to try to get started tonight with this additional testing. |
