Super Neo 29 Power Supply (S8XA-500)

[M3RI064]

Hello all, I have been trying to zone in on an issue with my cabinet not powering up the monitor. When I power on the machine, the board will come on and play blind but I can definitely tell that the monitor is not powering up at all. Chassis has been sent in for repairs and now proved to be working on repairmans test bench. So now I'm moving on to the power supply.

I want to test the AC outlet where the monitor plugs into but my multimeter will not fit in the prong slots.

Is there any other way to test this section on the power supply.

Also, any possible leads on a replacement psu I can purchase or maybe even capacitor replacements.


Thanks

It's just an AC outlet, you could plug anything into it to test, like a lamp.

Otherwise, you can buy a 2 lead tester for testing wall plugs at Home Depot, Lowe's, etc. for around $10. Or you could use that $10 to buy new leads for your multimeter.

Alternatively, the FL UNIT connector outputs AC on the same circuit so you could test there.

Wow, I did not think of that!
I did this test using a phone charger and sure enough, the phone started to take a charge.
So with the PSU and Chassis out of the way, I may just have a blown tube? I guess?

Time to start researching, thank again for your help.

Is it possible that my test with the phone charger is not good enough? Like, could the psu give off enough power for phone charger but not enough for monitor?

I doubt it. Your tube is probably not "blown". Maybe the chassis isn't hooked up correctly? Or maybe a fuse is blown? Just throwing ideas out here.

Also, FWIW the Hitachi tube in that cab will take an MS9 with some simple adapters or light modifications. Remy sells kits on ebay for adapting an MS9 into your cabinet.

Good luck!

Thanks for the info. I will definitely look into that.

*Update*

Last night, I decided to start to mess with this thing again. All out of troubleshooting options, I decided to start from square one. I flip the power switch on the PSU, the light and game board start up, and I kid you not, 5 seconds later I hear the monitor power on. WHAT THE HECK!? I played it all night last night and turned it on first thing this morning to make sure it still works.

Happy to say that it is still working. I don't understand it.
