When i power up my line 6 spider 3 ( i think it has two 75 watt speakers) all the lights work but no sound at all no static or speaker sound even at full volume. cable checks out, but even with a bad cable you would hear some amount of noise static or white noise if power is going to the speakers. the on board tuner also does not work. the amp is two years old not used very much maybe 20 times total. is there a fuse internal can't find any thing on the outside. thanks for the help

A pilot light means almost nothing other than the power cord is plugged in and hot and the switch is on. In this case, other lights run from various DC supplies so the inout fuse is presumed to be good... NEVER replace a fuse without knowing what caused it to blow or you will usually do more damage within a unit. There are several power supplies and you will typiclly find +/-15 volts on the op amps and 3.3 volts on the processor logic. Unless something simple like the speaker cable falling off this will NOT be a DIY repair. I would look to see if this speaker cable might have fallen off and ALSO check if you get any sound using headphones.
