I am having trouble with "slight hum" with Pioneer PL-A45D TT

So I grabbed a pristine TT (apparently not that pristine since it hums a bit") and now I have a slight hum when the needle hits the record. With that said I have tried some trouble shooting different speakers, AMPS etc and ruled out that. I have also tried cleaning contacts. I am not one for opening it up and changing things since I dont have the knowledge to do so. Any suggestions on remedy? Thanks in advance. I know this is not a Top shelf TT however it matches a Pioneer system I put together for my collection and would like to be able to use it without the hum.

Does the phono interconnect cable have a ground wire on it? Have you grounded the TT to the phono pre-amp/pre-amp/integrated amp to which you are connecting the phono cable?

Make sure you have a ground wire between TT/arm and preamp.

Yes I have proper connections of ground to bot TT and receiver......same problem with all 3 separate connections i tried. Most likely an internal issue one that I sadly cant fix on my own.....sad this TT is in MINT condition either its junk now or its gonna sit ....not worth having it fixed for what I paid it will cost more to fix than what I have into it. Win some lose some ....
