Marshall JVM 410C Sound on wont work.


My JVM 410C doesnt have any volume coming from the channels.


One switch works green yelow, not red.  Works fine with switch two.  Switch three works green and yellow, not red.

switch four doesn't work at all. 


No sound out of these channels without footswitch.  Same results.  Now, making a poping noise when turned off.  I just got htis amp in June.  Played a few weeks and then boom, nothing.


I tried using the FX Loop in back.  That's when this whole thing started.  As I correctly plugged in as instructions say, it immediately didn't make sound in these channels.  Unplugged, guitar going straight in, same stuff.  No volume through these channels.


The tubes are red, all glowing.


I need help.  Thanks.
