The problem is the fact that the new receiver has no phono input. The phono input has an extra stage of amplification built in. Your receiver is working fine. You need to purchase a phono pre-amp. These run around $20. Connect the turntable to the preamp and the presmp output to any line level input on your new receiver and everything will work as expected.

Hopefully this post isn't too late... That receiver has the ability to disable certain inputs. The easiest thing to try is to do a factory reset.
1. Turn off the receiver
2. Hold down DISPLAY and PANEL UP/DOWN buttons and press power.
3. All Clear should appear on the screen.
Unfortunately, this clears out all of the other settings on your unit. It should, however, re-enable the inputs.
Let me know if this helps!
