Make sure the connector from the tonearm to the junction box is plugged in all the way. It should kind of "snap" in. It might look like it's plugged in, but make sure it really is.
Also make sure the stylus is pushed all the way into the cartridge body since it is removeable and might not be seated all the way in.
