Electrocoin Xenon: power questions

[Diewrecked]

Hi all

I have four Electrocoin Xenon cabs in various failed power states:

One is absolutely fine.
One the JAMMA connector is fine and the speakers are fine (you can hear it) but no power to the marquee light or monitor.
One there is no sound but the JAMMA connector, marquee light and monitor are fine.
One is DOA - nada (I replaced the plug fuse but the power cable is hard wired).

I've not started diags yet but the obvious initial approach is to take the PSU from the fully working cab and try it in the others to see what works, but idk how much I'll prove doing that. Are the PSUs modular? And if so does anyone have a schematic for what powers what please?

For the speakers issue do they have their own power line? I was thinking of ripping them out and just sticking USB speakers in there (I'm replacing all the boards for MAME PCs) but I'd like to get the originals operational if I can.

Thanks in advance you guys!

Hi
Do they all have the same monitors ? All of my Xenon run Hantarex 9110 but have seen xenon’s with Polos also. I would check the 2 monitors in this working set up to rule out monitor faults.
I have a combination of Hantarex psu 200/250 (schematics available online) and also Electrocoin psu modules with step down and switching supply.
Perhaps it is worth checking the coin door switches are functioning correctly on problem cabinet 2 , I have had this fault before where the power is not reaching monitor or marquee.

The stock Hantarex power supplies are a bit naff, mine went bang after about 4 years from new, replacement is still going strong - good quality is always worth it.

Thanks @Flyback2021. They're all running Hantarex MTC 9000s, although on two there's no power to them like I said. So it's possible the PSUs are different but I got them from the same place at the same time (holiday park closing down) so I'd expect them to be the same. However from the sounds of things there are different PSUs used in these cabs if you're saying yours are different across your cabs. I'll get them out and take a look then report back.

Presumably then some PSUs are modular and some are not - and I'll need to replace like for like per cab if they do in fact turn out to be different...

Thanks @LHantz - what did you replace yours with please? I'm all for "good quality" but idk what is and isn't worth buying here. Thank you!

Perhaps it is easiest to post some pictures of what you have ?
I have my Hantarex PSU serviced and they all run well. This is other power supply type which I have in another xenon.

I think it is a Suzo Happ one, I can double check tonight. My Monitor is a Polo 1 though, FYI
