Hi @ mitchell schmidt 21
You will have to open it up and and use an Ohmmeter to check the connections from the needle cartridge all the way through to the control board preamp input.
If that is OK then the control board needs to be checked, initially for any obvious problems such as burnt out components, loose wiring or dry joint solder connections etc and then "live" testing may be necessary.
if you spot something (or even not) and are not quite sure post some close up images back here. Here's how to do this [guide|21499]
