I think you might be in the Utility Menu. Try pressing the UTIL button.
If that doesn't work you could try to do a Factory Restore.
To restore the Mustang amplifier to factory settings:
1. Turn the amplifier OFF.
2. Press and hold the EXIT button while turning the amplifier ON. Continue holding the EXIT button until it is no longer illuminated.

There are often undocumented ways to reset these kinds of devices (anything with digital controls).
Try the following--or different combinations of it...
With the amp plugged in and switched off, use three fingers to apply pressure to the buttons like this:
@ O @ O @
The @ signs are the buttons to press.
While holding these down, switch on the amp and see if it hard resets. If that doesn't work, try this:
O @ O @ O
Etc. Always start with the amp switched off.

The following is what I found in a search ... BUT ... it erases all user presets. You will lose all modifications/tones that you created or imported from the Fender Tone community (I have the Mustang GTX-100)...
Press and hold the EXIT button while turning the amplifier ON. Continue holding the EXIT button until it is no longer illuminated. The FACTORY RESTORE function will erase all user modified presets.

My gut impression is you are looking at fault codes on boot up.
Hopefully it's not the BIOS equivalent fried. I'd try and hook up to a computer and try and reinstall the firmware via Fender Fuse.

Fender has discontinued Fuse support completely, so it took me quite a while to find the firmware and fuse installer. I did eventually succeed in re-installing the FW. I even managed to update it by a rev or 2. Unfortunately, it has made no difference. I still have this issue.

Hate to say it, but you may have lost a combo but gained a 1x12 cab.
As far as I'm aware, Fender never repaired these under warranty, they just replaced them.
Your only option may be to find a used circuit board on ebay and swop it out. Hopefully someone will have the magic cure ...

Yes, I'm tending to agree with you. The fact that it only works with fuse leads me to believe that the board is dead.

OK, my brains ticking over slowly .... Mines on the other side of the Irish Sea, so I've hardly seen it in the last year. As I recall, you can load presets into Fuse and play them through the amp, they don't need to be on the amp. Maybe the memory on the amp isn't storing the presets, but it will play them via a computer?
If you have an Android phone get Remuda, it does the same as Fuse - only better. Be a lot easier to control the amp with a phone than hook up to a computer.

How did I miss that, sorry about that! Good luck to you, hope you can get it corrected.
This is what I suspect as well, the amp is at least usable with a computer. So it's not a total loss!
I have an android phone that I don't use but it has USB 3 and the amp is mini USB, I'd have to find a USB 3 to mini cable. I'm not sure such a thing exists.

Sure, USB to mini USB cables exist. I have several of them. It doesn't need to be USB 3. All my cables are USB 2 to mini USB and work just fine whether I plug the USB end into a USB 2 or USB 3 port.
Sorry, I meant USB C. The android device I have is USB C, so I'd need USB C to Mini USB.

I see you're in Canada. Buy this USB C to USB 3.1 OTG cable and this USB 2.0 to Mini USB cable, plug them together and you're good to go.
You guys are the best! Thank you!
