I have a fender m-80 lo-250729 amp. went to play and none of the knobs change the sound, volume or input. Overdrive channel or reg. What happened and how do I fix it

Do you mean the amp produces no sound or you can't change the sound it now produces? If it does not light up or produce a "pop" at switch on check if there is a mains fuse blown. Should be one next to the mains power lead or if it uses an IEC mains conn' the socket might have a fuse in it.
Replace with EXACTLY THE SAME RATING. If that blows, tech time.

That's a pretty old amp. Hopefully its something simple like a fuse (if you are getting no sound). Are the tubes lighting up?

Flip the switch that says POWER.

It's been three days....do you think he figured it out yet? 
Maybe it's just out of gas.

I just looked it up, you're correct - solid state. Fender Amp's 'grey fuzzy' era. Glad I was not looking at amps at that time.

Yup, gray fuzzy. They weren't terrible for a small bedroom SS amp.
