Sudden problem with turntable

Could you or someone bumped your counter weight and added tracking force, your head shell screws were loose and cartridge moved, to troubleshoot you could back off on tracking force or adjust vta. Did you check the suspension of cartridge was riding low close to album? I use magic eraser, I have a vpi machine but get best results cleaning albums with a hand held steamer with cleaning solution and rinse with lab water or distilled . Hope you find problem it can be aggravating, been there.

Sorry, meant Vinyl Engine for protector

Go to Vinyl Asylum and download the best protractor for your arm, put it on your table and follow the lines it's easy. If you think it's low on oil maybe from shipping don't use it till you top it off, look in there with a flashlight. First thing I would do find recommend tracking force for your cartridge and see what your tracking force is set at, to much force will dull sound. If you don't have a tracking force gauge make the arm float with the counter weight,set dial to zero without moving counterweight, then turn counterweight to cartridge recommended tracking force. Just be careful of not damaging needle while making it float.
