Mystery lightning bolt on GDC SR-1000 server screen

[Barry Floyd]

Came in tonight and found this mystery lightning bolt on the top right corner of my server screen. It doesn't stay there all the time, just kinda randomly appears and goes away. I know my warranty just expired, but I'm not sure if that's it.
I loaded up last weekend's playlist (since my keys were still active. It played just fine and the keyed content (Moana 2) played fine.

Any clue?

[Mike Blakesley]

Did you reboot the computer? Sometimes I'll get some random thing that won't go away until I reboot.

[Barry Floyd]

Didn't try rebooting it. I spoke with another drive-in owner tonight and he thinks it may be a warning that the power supply may be failing on the micro computer that we use to log in to the server. It has the same graphics as the lightning bolts found in other places on the GDC server so I'm not sure if that's it or not.

I'll have a technician log in tomorrow and see what's going on. I've got an issue with numbered keypad on the control side of the projector too, I think it no longer works. I'll have him look at that too.

Do you use a Raspberry Pi for connect to the server? Seems the low power symbol of the Raspberry Pi.

[Leo Enticknap]

Whatever it is, it isn't being generated by the SR-1000 itself, because it's outside the SR-1000's web UI window. It's coming from the device being used to view the web UI.

I'm not sure if its a Raspberry Pi, but there is a tiny computer like device about the size of a pack of cigarettes inside the base of the projector that is used to access the server. I was told by the dealer that's its a small computer running Windows 10. I'll call my dealer this morning and inquire.

[Barry Floyd]

Dealer confirmed its a power supply issue with the Raspberry Pi that's used to gain access to the web GUI of the server. Amazon to the rescue.

I know this lightning bolt symbol from standard Rasperry PIs (the SR-1000 uses a Rasoberry PI internally).

It signals a weak 5V power supply line (typically from an underrated USB power supply when using standard PI devices and addons). I don't know how the 5V is generated on the SR-1000. It's probably an onboard voltage regulator.

[Marco Giustini]

Indeed, the issue is more likely to be on the 5V generation line I'm afraid.

[Carsten Kurz]

The interesting question is - is this actually from the PI that is built into the SR-1000, or does Barry use ANOTHER external Raspberry (instead of a notebook) to access the SR-1000 web interface. Then it would probably just be an issue with a cheap USB-power supply.

As the SR-1000 does not have an external monitor connection, I would guess what we see in the screenshots is not the internal PIs screen.

[Barry Floyd]

Correct. The SR-1000 doesn't have any external monitor connection, so we were provided an external Raspberry Pi computer type thing that hides inside the base of the projector. It's about the size of a pack of cigarettes and has 2 or 3 USB ports, an Ethernet jack, and a micro USB power connection. The monitor in my photo is attached to that external Raspberry Pi. It's only use is to provide a web GUI to access the server's web interface. I could hook up a laptop to the projection network and dial in that way, but this setup we have is what came with the server from our dealer.
My new 5v 2.5 amp power supply I ordered from Amazon came today, so I'll get it hooked up tonight at the theatre when I get there. It's going to rain all weekend long here, so I'll have plenty of time to poke around inside the guts of the projector base.
