First, plug something else into the amp with the same cord to make sure it's the guitar that's the problem. it's more commonly the cable, then the amp, then the guitar that goes dead. If it's indeed the guitar, check that the jack is wired correctly and that the jack contacts are gripping the plug. Next check the switch, then the individual pickups. If you haven't done this before, you'll be time ahead to take it to the shop. Normally labor rates are minimal, and any decent tech can dianose the problem in short order.

No, that won't hurt anything.

whatever jack you need for whatever you are using

This unit needs to go to the shop. I beleive you've got a blown motherboard.

You might have a shorted rectifier or capacitor in the power supply circuit. Check that first.

You have a short in the machine take it in for repairs

I suspect you have your system wired up in such a manner that the amp is seeing too low an ohmage from your speakers. Check what the minimum ohms your amp will push and wire your speakers up so the load doesn't go below that figure.

Sorry I remember now this is a solid state amplifier,
try electronics spray contact cleaner in the pots of the amp, you will need to unplug and remove the chassis of the amp to do this, there are little notches on the pots, that's where you want to spray, and work the nob back and forth completely, do this to all volume, treb, bass, etc... I know this will fix your problem because I have done this about 100 times servicing amplifiers, the way a solid state circuit works if the pots are dirty the circuit doesn't complete properly causing volume issues, really hope this helps?

Your Dbs are not correct. You are going to need a pre amp/mixer inline to make the necessary corrections to your audio output.

Remove the retaining screws from the top of the amp and the screws holding the back lip of the amp (faceing down) on the rear of the cabinet. At that point, it should come out the rear of the amp. It will be snug. You may also have to remove the handle from the top of the amp and the metal corners for clearance.

Press and hold the 'A' or 'Clean' button in while turning on the amp's power. Hold for 5-8 seconds.

The Behringer PMP2000 uses Speakon jacks on the speaker cables. The outputs are located on the back panel. Which ones you use is determined by how you configure the mixer. The Main inputs are located on the right side of the face of the mixer.

There is no other fix than to replace the volume pot. if you are not familar with working on electronics, it will require a trip to the repair shop. Unfortunately, the repair charges will most likely be more than the cost of just replaceing the amp.

I'm not sure i understand you question? You would come out of the left and right XLR outputs on the board and into the two left and right XLR inputs on the amplifier. If you need more help and the dealer who sold you the gear isn't willing/able to assist you, Peavey customer service is quite good about walking people through problems. You can reach them at 877-732-8391.

Try reloading the factory presets. If that doesn't work seek out an experienced audio technician.

I am guessing it is solid state? If it were tubes it would be an easy fix but the solid state amps are very hard to diagnose and repair. I think the Guitar Center has a repair department and they probably know the trouble shooting steps. I am guessing it is a board, but the way to trouble shoot would be to know how much current should be flowing to individual leads. I do not have this information, but you will need a multi meeter in order to start the process. No reputable repair shop should charge you any thing to give you an estimate.

Yep! Get a decent audio interface that attaches to the PC with a USB connection and uses BALANCED lines to your mixer. I use a UA-25EX Roland/cakewalk as an example. (about $200 and there are cheaper units such as M-Audio Fast Track MKII ) Note these interfaces BOTH record and playback with two channels for stereo.
Essentially the audio board that is in PC's and Laptops are too near the switching noise of the processor and some of that is just bound to get into the audio lines as they don't even have balanced audio lines from the computers. Make sure you use either TRS or XLR balanced cables from whatever interface you get. Also connect ALL interconnected equipment to the same power source or receptacle. You can try to reduce the buzz with the mixer EQ's with what you have, but that sacrifices audio quality.

You should be using XLR to XLR cable, NOT a 1/4 inch cable. There is a problem of the 1/4 inch being the unbalanced version and is not compatible with this unit's input.

Use the XLR to XLR mic cable and it will work fine.

The cable you have would work for one of those cheap Karaoke machines...
