Try some troubleshooting to check whether its the turntable or the the receiver.
What happens if you exchange the output cables of the turntable from left to right. Does the problem shift?
Does the sound changes from left to right speaker?
Similarly try on the inputs of the Receiver.. does the problem shift...?
This way you will be able to isolate the problem, whether with the receiver or the turntable....
Let me know, we can trouble shoot it further....

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.

It is rare for the actual input connectors to fail. More likely, either the solder connections need to be re-flowed, or the switching IC is defective. If you can solder, try resoldering the pins of the RCA connectors. Look closely at them and see if the PC board trace is broken. If the resoldering fails to resolve the problem, look for a switching IC with about 28 pins. It may be marked TC9163 or something similar. That will be the audio switching IC. I would change that next.

Actually, Denon used a thermal fuse in the primary of the power transformer. Have a tech check the primary winding and see if it's open. if so , have it bypassed
