Was listening to it, turned it off when we left, came home, turned it on and there was no sound. Nothing at all, not even a crackle, speakers are silent. Everything else seems to be working, though with no sound, kind of hard to be certain.
If your head phone is connected to your system there will be no out put to the speakers. Please remove the head phone and try. If this does not solve your problem then there is a possibility of defective audio output IC.

You have two options. First a faulty cartridge. Or a faulty pre-amp in the main amp.
You can find out if the cartridge (and amp) are playing up. By removing the connectors on the cartridge.
Then with the volume turned up to about half, with your finger, touch each one of the wires one at a time. It will not harm you at all. But you should hear a loud buzz on one wire on the right and a loud buzz on the left on another wire.
The two other wires will either produce a crackle, or a tiny buzz, or nothing at all.
If you do hear a loud buzz on two wires. The cartridge is faulty and needs replacing.
If you hear a slight buzz on them or weak sound. There is either a bad connection between the deck and amp. Or the pre-amp inside the deck which is only used by the record deck so will not effect any other function, is faulty.
You can remove the record deck connections to the amp and again with the amp on half full, touch the inputs with your finger. If you are not hearing a loud hum or buzz, the pre-amp is faulty. If you do the connectors are faulty.
It sounds like a part probably an IC or Transistor that has become sensitive to heat and when it gets warm it acts up. Returning to normal when switched off. The only way to find out is to spray any suspect part with Servisol Freezer spray. You have to do this to one at a time to any part and wait while it acts up. If the freezer spray stops the crackling you have found the faulty part.
Sounds like an amplifer fault. Many of these Midi system use a large black IC attached to a metal heatsink. They control both the power amp and pre amp on both channels. When they go wrong they can cause all sorts of effects,
If you can repair things I would look at that. If not get ready for a large bill. If it's the IC some are expensive, it does most of the work!
Yeah i had that same problem. You know the chord? The cord you plug in from outlet. The square cord you plug into your speakers.. yeah the "DC outlet" is supposed to be UP. if you have it the wrong way in there it wont work and will make a crackling sound.
Sounds like an internal loose connection somewhere, possibly anywhere, a connector on a pcb, a dry solder, loose pin on an IC. Tough for an end user to solve this, would entail opening the unit and investigating. I checked the rear panel in the op manual and this model has no ribbon connectors else i'd have asked you to check them.
