You can use a small screwdriver to remove the C clip in the center of the platter. Then remove the platter and reinstall the belt. It can be a little tricky to get the belt back on. If that fixes the problem, then I would look online and order a new belt as yours may have stretched out and will keep falling off. Here is a link to purchase the belt if needed.

This is almost for sure just a connection that came out when moving or during shipping. Pull the back, off and look for some wires just hanging. Most likely it is an input.

I was asked to further clarify problem, but not much to add when there is absolutly no sound it is called silence from the speakers when unit is plugged in, turned on (sounds like speakers engage) one of the five choices is chosen to listen to and no sound comes forth to hear. How can I get inside the unit and check to see the speaker connections?

Turntable belts can be found on EBAY.

The unit will record to CD from the turntable, cassette or the AUX port. Place a blank CD-R or CD-RW in the CD tray. (Note: CD-RW discs may not play on other CD players.) Press the Phono, Tape or Aux button to select your audio source for recording. (For Aux, you will need to connect the source device to the AUX port in the back of the ITRR-501.) Wait for the CD disc to load and check for any indicator lights (you should see the "NO TOC" and "CD" or "CD-RW" lights lit). Select your Track increment (or Auto Manual for unattended track formation).Press Record button and the up arrow to adjust the recording level.

If you are recording from an LP, put the tone arm down on the record. For all sources, press Play. Press Stop to end recording or Pause to temporarily break the recording. Press the Track Increment button to advance the track number if you are doing so.

To finalize your CD-R to make it readable on all players: after stopping the recording, press the Finalize button.
