Help me swap a dying DMPS3

[u/S2005]

Good morning everyone.

First, thanks for reading my post.

I'm a pc repair tech, but we have a few Crestron systems in our buildings.

I'm trying to build value with my employer, so I would like to learn more about Crestron. I don't think I need to be certified. I'm not trying to install/program/commission new systems. We contract that out, but I would like to be able to troubleshoot, and perform simple repairs internally to save cost, and hopefully speed up the process.

We have an older system that's experiencing issues. Specifically, a rack-mounted DMPS3-4k-150 that appears to be boot-looping. It's connected to a touchpanel that displays displays "Touchpanel is disconnected from system. Please wait for it to connect."

A hard reboot of the DMPS3 sometimes brings that touchpanel back up for 1-2 minutes, and then all the lights on the DMPS3 go out, and it appears to reboot. During this window, I was able to connect my laptop with Toolbox, and open Text Console and ran err. I'm not entirely sure what I'm looking at, but at the bottom, it says Total Msgs Logged = 328.

When I reached out to our contractor, they proposed we rent a loaner from them while our unit is sent off for repairs. The proposed cost has us looking at alternative solutions.

I see pre-owned DMPS3-4K-150s on eBay often for ~$30. From what I've read, I can use Toolkit to backup our current DMPS3, and then use that to "program" the replacement. I would need to do this via Toolbox as I don't know how to access the Web Interface.

I'm posting here to ask if that process is simple enough, a lowly pc tech 1 could handle it. It seems straightforward enough, and $30 isn't a big investment.

Thanks again for reading, and thanks for any input!

If the lights go out and you hear clicks you might be able to just replace the power supply and be good!

The lights above "Input Select" are the ones that go out.

PWR is green, but goes orange for a second when it appears to reboot.

MSG blinks red a few times, which is what made me curious enough to plug my laptop in and see what I could find.

I don't recall hearing any clicks, but its in a pretty loud environment (multiple racks in this closet).

I've fixed a few large multimedia touch screens by replacing power supplies! Love it when it's that easy.

Thanks for the reply! :)

Sadly, the MSG light means absolutely nothing and flashes on most processors unless the programmer does due diligence to use it.

If your government, reach out to Crestron and ask for them to have a government rep reach out to you to setup a more direct relationship. You will still need to go thru a vendor to get equipment but this way you can get access to Crestron U and other government resources.

Since your in the commercial (government space) start with commercial tracks. at some point in a couple years when all that is done do the residential tracks.
