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?

Your vid is so quick and hard to read that it's impossible to be sure what exactly we're looking at. It *looks* like this is just a plain, old, standard DVD player - no AM or FM tuner, or ability to select other inputs like CD, Tape, etc. Can you look at the rear or bottom for a model number? That will help considerably.
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.
Make sure your FM antena connection is good. A receiver will not pick up an FM signal without an antena. Even a small piece of wire will work to test. If the Tuner section is bad, an external tuner can always be connected to an Aux input. Due to cost, it may not be cost effective to repair this unit.
Hope this helps.
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.
You are using a new HD Cable box, that are using componet video cables for HD, Unfortunetly this receiver does not have componet inputs, so you will just have to run the audio from the televison directly to the receiver by connecting the video out and audio out from the television to the receiver's video Input one. This will require a normal RCA composite cables yellow,red,white. Connect one end of each of the cables to televisions output terminals, and the other to the input one on the receiver. Note: Your TV might have a seperate term called Monitor out, Connect the yellow here, and the red and white to audio out. You can do the same for the DVD but you have to use the same cables,Also the television will not display HD picture this way as this is not a HDTV Receiver. If you just want TV sound to the receiver then do not use the video(Yellow) cable just use the audio out terminals from the tv and connect to Input one on the receiver. you can do this with the cable box also but you have to use RCA type cables . If you want the full HD experience then a new up todate receiver is necessary.
Check the setup menu on your TV. Many models require that you choose between using the internal speakers and using the speaker outputs. Sometimes the TV menu choices are "FIXED" (audio output) or "VARIABLE" (internal speakers).
Most if not all turntables would need to be connected to a PHONO INput which is high impedance with a high gain pre-amplifier stage. It will not work when connected to an AUX, CD or any line level inputs. Alternately, if your amp does not have any Phono Inputs, you can feed the turntable output to a preamp which can then be connected to any any line level inputs. An example may be found here or here. Additionally, there are some turntables with a built-in preamp.
Hope this be of help/idea. Pls post back how things turned up or should you need additional information.
