Help, No sound from Turntable


Sat down to listen to some vinyl and nothing.  Dead as a door nail.  Yesterday it worked fine.  Digital works fine.  Place the needle on the record and not a peep.  Is there anyway to diagnose where the issue lies?  Is it the cartridge?  Phono pre-amp, pre-amp, etc?

Before going out to get a new cartridge do the following.
Disconnect cartridge pins and touch the tonearm leads at headshel, if nothing happens then check for continuity internal arm wiring, then tonearm cable and so on. It is unlikely that cartridge, cabling, phono, preamp are faulty.

You have lost both channels so you have to look at issues that would affect both channels such as switching in the phono preamp or preamp section. First plug another source into the input you are using for the JC3. If it works then you can turn your attention to the JC3. Does it have power? Is it hooked up right? Wires do get pulled out. My cat disconnected the TV once. You have to work your way through to determine where the problem is. Fuses might do this. Some units have them hidden inside. Relays are another weak point. 
Probably the JC3+ has some sort of LED on the front panel to indicate power on. Is it lighting up? Even if it is, have you checked the main fuse? Because in some cases the LED may run off a different circuit from the electronics; some designers do that to keep noise from the LED out of the audio path.  In that case, the main fuse may be blown, and you are not alerted to it, because the LED remains on when you apply power.
As suggested, I plugged my streamer into the input that I typically run the phono-preamp into on the Bryston BP26 preamp (the aux input) and it worked fine so that pretty much rules out the Pre-amp being the issue IMO.  

I took the cover off the Parasound to check for internal fuses. There are two and both look fine.  Everything on the Parasound lights up as it should.  

I've check all cabling.  Everything seems to be fine.  Note that one day it worked fine and the next without any change there was no sound.  

Not sure how to check the tonearm wiring or cartridge other than going down the road of trying to buy a cheapo MC cartridge just to check out.  

Appreciate all of the guidance.  I'll keep you posted on what it turns out to be. 

Best,
