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?

What Mijostyn said. Fuses mostly do show a visible sign that they are blown, but you need to know what to look for. The most certain way to check the fuse is to check whether there is any resistance from one end to the other. A blown fuse will show infinite resistance across it. You mentioned finding some fuses inside the chassis. Without knowing anything about the JC3, that seems a bit odd, because fuses are typically mounted on the back panel below the IEC inlet or somewhere in that vicinity. If there is a fuse there, that is the one that would supply the audio circuit. In case you haven’t already done so, be sure to check that one.
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.
Have you tried turning it off, and then turning it on again? Is your preamp set to “phono”?
