Reply to I think I need new RCA Cables for my technics?

So recently i've realized one of tables is hardly outputting any sound out of the left monitor. I'm not sure if its the ground or one of the RCA's. Any suggestions? When I pan to the right monitor it sounds perfect but the left is maybe half as loud. If I need to replace the RCA's im believeing about just doing a full overhaul and self grounding them as well. Any input helps, thanks in advance .

Side note: I have a pair of MK5's if it matters.
