I've been using my Digi 003 console since it came out, currently with a Mac Pro 2013 and a Presonus DigiMax LT and Pro Tools Studio 2023.6.
The other day in the middle of a recording session there was a power surge and/or brownout that wasn't bad enough to reset anything but it was enough to put the 003 in a weird state. Pro Tools was still "recording" but nothing was happening. I was unable to stop the recording, I got an error trying to stop it, and had to force-quit Pro Tools. After resetting the computer and 003, the inputs coming directly into the 003 no longer worked. The DigiMax LT still worked, however, and successfully sent its digital input to the 003 and Pro Tools. As far as I know, there's no way to reset the device. I wonder if there's a fuse inside for the analog inputs? All 8 inputs don't work, 1-4 on mic or DI. Probably time to upgrade anyway, but let me know if anyone has any ideas. Also a big FU to Entergy, the worst power company in the USA. |

You can try this.
Put the 003 into standalone mode (hold Aux In -> 7/8 while powering on). See if you can route analog input to output internally. This bypasses the computer entirely. If inputs still don't pass signal, that rules out software/driver issues. Even if it’s unlikely the firmware was corrupted, a reinstall could reset any low-level config: Use Digi 003 Firmware Updater (from my.avid.com/products#Myproducts) and re-flash the unit. If you're on Pro Tools 2023.6, ensure that your 003 is still supported — note that Avid officially ended 003 support years ago, so newer macOS or PT versions can act erratically.

I can't remember, but I'd hope there are internal fuses (which might or might not look like common glass fuses or could even look like a surface mount resistor).
If you are handy and understand electrical safety and want to play there are obvious things to check, starting with just look for a fuse and/or any obvious component damage. These voltage spike damage should be fairly easy to isolate down to a board level and maybe replace that board with a used one even if you don't want to try component level repair. It's almost guaranteed to be not justifiable to pay somebody to do repair work, just buy another used 003 or newer interface. OTOH if you want to play and maybe fix it yourself that can be interesting to do. If you want to test stuff always start with supply voltages. You should find test points on the power supply board, marked with their voltage. Probe those voltages with a multimeter and test if they are close to the labeled values. Try hard not to kill yourself when working near live mains power. If you see fuses on the outputs of the power supply measure voltages on either side of them. With power strikes it's very likely you'll find damage on the power supply, voltage spikes can take out power supply components (regardless of things being fused or not). You might be able to find those from burn marks or physical component damage. Possible but less likely to be damage on the analog board (unless you zap the analog inputs with a large voltage spikes and that does not sound like what happened). Ideally the 003 uses an separate transformer to power the analog stages, but either way if you are not getting DC output voltages at the test points you can check the AC voltages present at the transformer outputs, sometimes a power spike can take out a transformer, but that's less common than blowing up downstream components. But if AC is there on the transformer outputs and no DC then you know the problem is on the power supply board between the transformer and the test point or output you are measuring... look for physical damage, consider repairing it or trying to buy a used replacement power supply board. If the problem is not on the power supply board then go to the analog board and find those rail voltages there, hopefully there are test pins on the analog board and test if they are the same as you measured before at the power supply, then test voltages at an actual input chip, look up a data sheet online for those chips measure the voltage at the V+, V-, and ground (for chips that deal with differential signals and Vcc and ground for any chips dealing with single sided signals, there will be multiple voltage lines V+, V-, likely a separate Vcc and GND, maybe more. If the problem is power supply related it's usually pretty easy to find (says somebody who collects vintage computers and spends time testing and working inside old power supplies). |

There's a fuse.
I don't know how it turned out for that person. https://duc.avid.com/showthread.php?t=391002

From that other thread that looks like a voltage protection MOV (metal oxide varistor... shorts voltage spikes to ground), a ferrite choke (to reduce noise in the AC signal) and a TR5 series cylindrical PCB mount/through hole fuse.
The TR5 fuse labeling looks like T3.15250V. That would mean T=time delay (slow blow) rated at 3.15A 250V (will be 250V AC in this case). It is not at all unusual for a MOV to be dead as well as the fuse if there was a big surge. All these parts would be easy to find at DigiKey or Mouser etc. If that fuse is on the AC side of the whole power supply then it won't explain some things working and the analog inputs not. If there are multiple parts of the power supply and this is only in front of the transformer powering the analog board then that may make sense. But ideally there should also be separate fuses on the DC side of the circuit between the power supply and other boards, like the analog input board (and again especially something that does not look like a classic glass fuse).

Thanks for your thoughts! |

(Update to above)
Oops, I didn't read carefully enough, those are the drivers (which I already have manually installed, thanks to a YouTube video) and not the installers for the firmware. From searching the web, it seems that Pro Tools does the updating itself once the 003 is put into Firmware Update mode, which you do by holding the Aux 7/8 and Mute buttons down on power-up, before launching Pro Tools. I got the "Waiting for Firmware Update" message on the 003, and then PT is then supposed to give you an option to update it when you launch it but of course the 2023 version of PT that I have does not include this. I can find no evidence of there ever having been a Digi 003 Firmware Updater application. In any case, I'm pretty sure it's a fuse or a blown component that happened when too much voltage came in the analog inputs. Not something I'm likely to be able to fix on my own. |

Also, I do want to thank the other 2 posters with valuable information about the possible fuse.
I may try to donate this unit to someone with enough electrical skill to replace it. I can solder basic stuff, like guitar wires, but precision soldering and component handling is not my forte. |
