Turntable cue not working on a Micro Seiki DD-20. I can pull it up but it just sinks down by itself. Need Fluid maybe? If so What kind and where do I put it?The cue lift has a small phillips screw but it doesn't seem to do anything. If I unscrew all the way, will it allow me to lift the cue arm off? Is this where I would put fluid? Any help would be appreciated. Thanks in advance. By the way this TT has 2 buttons for the cue, naturally one for up and the other down. Nothing happens when pressing either one.
