Question about Audio & Video Receivers
If it is like the one I just fixed, the sound had just disappeared gradually when playing. To fix this one first and foremost unplug the unit. Remove the two top side rear bumpers, the 2 screws on the upper back metal ledge, you can feel them if you run your hand along this lip and locate, then remove the 2 wires connected to the speaker, ( just connector clips). Remove the power plug clip(one screw) then the 4 top side screws, I like to hold tray up with one hand and unscrew with the other. once these screws are all the way out the tray should drop down a bit. Just slide to the rear and rest it on the lower part of the cabinet. The return 1/4" jack is the dirty one that needs addressed but why not do all of the jacks while we are here. You will need a contact cleaner solvent. I use one designed to be used on printed circuit boards. You should be able to find some at your local electronics store. The cleaner should leave no residue after it has evaporated, check the cleaner you have and make sure it is the correct stuff. Next we will spray all of the 1/4" jacks, just spray enough to coat them good, let dry and repeat. them reassemble the amp and plug and play. Don't forget to reattach the speakers. This should fix your problem.

I had this problem with a bandit I just bought. I think the problem was the effects send/return jacks being a bit sticky. give them a clean, or for a quick fix plug a patch lead from the "send" jack straight back into the "return" jack!

First unplug amp to avoid electric shock. Then carefully unplug speaker and reverb wires. Then take the 4 screws out of the top of the case. This will allow the box, housing the electrical components to drop down.Slide the box out through the back of the case and look for 3 glass tube fuses.Check each of these to see if the filament inside isn't broken or burnt into. May not solve your problem but at least it's a place to start troubleshooting.
