If the amp started to do this on it's own, seems like it is most likely related to the power source it is plugged into. Have you recently moved the amp to a new power outlet? Has there been any power surges in your area lately? I would suggest trying a different IEC power cable with the amp as well, possibly use some sort of power conditioner as well to ensure you have a clean power supply. If that does not solve the problem, the hardware will need to be assessed by a Line 6 Service Center to determine the cause of the hum.
If the amp is out of warranty, I suggest you contact a local service center to inquire about their repair charges, you can locate one in your area using the link below:

I have the same problem and I'm not sure if it's fixed.
I have my amp for just 3 months and just last week I noticed the gradual build up of hum and buzz after playing for just a few minutes. It cycles from low hum > loud hum > loud hum and buzz and then popping sound even when all volume is off and no guitar connected. I can't stand it.
I considered sending the amp to a technician but it's heavy and I don't like the fact that I have to pack it up again after throwing the damn box it came with... pff.
My amp never left my room and always plugged in to a UPS (uninterrupted power supply) with built in surge protector.
I tried line6don's suggestion to try diffrent IEC power cable but no change. Tried a different powersource and no change.
BUT TODAY I let it hum, buzz and pop for several minutes turned it off... plugged it back in and the hum and buzz is gone.
Should I send this back? Or is the problem fixed?

Okay guys it's not fixed. I tried again this evening and it's humming and buzzing again.
It's winter here and I live in an apartment complex, so probably the power going to my amplifier is not clean and causes my amp to hum and buzz.
Which power conditioner should I try? Would this fix my problem? Help.

While we can't suggest a specific power conditioner, one thing to try is another location altogether. If the noise goes away after using a different building's power supply, the issue is with the power at home. Otherwise, a technician would need to check on it. One thing you can do to lessen charges if you have to ship it is remove the head from the cabinet, just ensure it's packaged to prevent damage.
