The game is working again . Thank you master Tovar, Astro X and Darksoft

Thanks for your comment. I am not sure of the broken leg below the board is the culprit but apparently there is no short circuit. I will try again to power it on

I separated the two boards and checked the resistance between 5V and GND on the JAMMA board. With the multimeter set to continuity mode, I sometimes get a beep for a fraction of a second, but most of the time there is no beep. I get the same result when checking 12V to GND. The resistance...

Thanks, That's exactly what I wanted to hear: a description of what needs to be done.

what kind of equipment ?

Ok, How to proceed ?

The diode was still functional. When I plugged the jamma board and power on, I measured the 5V with my meter and it was 0.87v. I calibrated the meter to 5V before plugging the jamma to the board

Yes, of course. It’s for when the board is fully functional again.

By the way do you have any suggestion, whether I want to replace the Zener diode 1z6.2, by a new functional one. Should be 6.2 V , 1 W, right ?

To do a cap kit ? It is not good ? Why ?

I’m currently gathering the capacitors for a Namco System 1 cap kit. The radial capacitors are relatively easy to find, but I’m having a much harder time sourcing the axial ones. Does anyone have any tips on where to find suitable axial capacitors, and especially, are there any brands or series...

Yes guess. Do I need to replace it with a new Zener diode to run the board or it can run without it?

Is it enough to prove that the diode is shorted ?

Thank you 🙏

Thanks for your message, I going to check this out So, would this basically be a safety feature? And could it be that, despite my precautions, my Supergun delivered a voltage higher than 5.6V?
