Superchamp XD Trouble

To the certifiable geniuses of this forum, I present to thee a quandary:

About an hour ago, I was playing through my Fender Superchamp XD with no issues whatsoever. I turned the amp off for about twenty minutes whilst I left to attend to something else, and then returned to resume playing.

Guitar plugged in, I turned the device on. However, all I got back were odd clicks and pops, and I immediately knew something was up. I turned it back off to try and avoid any potential damage, and investigated from the back of the amp. There were no odd smells or sights, and the fuse hadn't blown so I figured it must have been a fluke. But when I switched it on again, despite the power LED lighting, there was absolutely no noise whatsoever, not even speaker hiss. I turned the volume up and down, switched over to the other channel, but to no avail.

With all tubes glowing at normal intensities, and no weird hums or fizzes, I assume it to be the speaker. When I attached the amp to my computer via the line out, I can record from it just fine.

Aside from the speaker, could anything else be causing this? Why would this happen in the first place?

Edit:

Laptop plugged into speaker plays music through it, so the speaker works. I'm at a loss.

Well, your pre-amp stage obviously still works so the problem lies in the power amp stage.

The glow inside your power amplifier stage valves could be just the heaters.

Likeliest explanations:
1) Blown power stage valve.
2) Failed connection to power stage valve.
3) Blown output transformer.

Had the same problems with my Blues Deluxe. Swapped a lot of preamp tubes but it didn't help really in the longer and the amp didn't feel reliable. Sometimes it worked well and sometimes I got crazy loud noises. Took the amp to the shop today, maybe it is a cold solder joint.
