I get a very noticeable hum when I select either the AM or FM input of this tuner. The CD input and other inputs sound clean, so I am wondering if there is any information about a power supply that feeds only the tuner module that could be causing this, ie a bad filter capacitor or voltage regulator. Any suggestions?

Please make sure that the connections are secure and proper.
Make sure that the sound is not muted.
Make sure that you've selected the proper input by INPUT MODE button.
Remove and reconnect the source.
connect a different device and check
check whether you're getting sound when listening to radio.
Tuner is only analog. As for the Video 1 input you need to go into the menu and change it to the digital port you want to use (optical, coaxial or HDMI) you can set only one input to each digital input port.
If memory serves correct, the VSX-3000 is from the late 80's. They are good receivers from that era. From your description, it appears the tuner module could have issues, since only the AM/FM has a hum. If all other inputs sound well, it points the the tuner module. These modules are not easy to repair (PCB with SMD highly tuned parts), and are easiest and cheapest to replace. Many VSX models of that vintage use the same part. Not sure how easy it would be to find one. They are a small PCB enclosed mostly in a silver shielding, with one or two connectors from the inside and screwed to the back of the receiver, where the antena connection is.
What I think is the problem here is that your A/V receiver may have a blown preamp for the turntable input. Or, although less likely, assuming that both channels sound normal when the receiver is set to a different input such as an FM tuner, there could be an impedance mis-match between the turntable's output and the reciever's input. But, the goal is to try simpler (and much more inexpensive), methods first. Try replacing the cable that connects your turntable to the receiver. If no difference is heard, then we should take another diagnoses.
I had the same problem, but it is not the tuner module! An
exchange of capacitor C899(100μF/35V) on the standby board has resolved
the problem. Under a dollar from an electrical store and you are all
sorted. 10 minute fix for those with a soldering iron.
Okay I am not positive I have this right as far as the configuration of the system but I will give it a shot. If you run the 722 to the tv using rca's you get the hum. I assume this as there are no inputs on a dish 722 receiver. I can suggest one possible solution which is to buy an rf modulator. It will convert the signal from rca to coax so you can connect as you wish. There are several types out there so ensure you get the one that converts from rca to coax. I would suggest the following configuration: Remove all connections from tv and hook 722 up via rca's to rca input 1 on the tv, check for hum. If it is present now you need a new 722 as it is passing to much power thru the connection. If there is no hum connect your cable and tivo to the tv via whatever inputs you have remaining. Lastly connect the DVD player to another input that is free. You will have to system through your inputs to view the three sources but should not have the hum. I hope this solves your issue. Thanks for using Fix Ya and let me know if I can be of further assistance.
