Can you make some sense? - Problem

My TT set up has only Right Channel working this morning. Left channel has faint noise at time or none at all. Last night was both channels were fully functional. Only two specific events stands out as different than usual. One: I let at the platter spin a little longer at the end of one side. Two: I have severe lint problem ( even after brush cleaning, every time I play) and have to clean the stylus more often with the LP # 9 fluid, and may be I might have allowed the fluid to trickle 'IN' the cartridge body.

I did some trouble shooting. The I/Cs from phono to pre are working and indicate the problem would be at the cartridge or the LH RCA termination. Although I did not touched nothing last night (but did disconnect termination to try something else a night prior- Historically I have had termination problem with this cable twice, but was on RH channel). Measuring resistance at termination shows no indication of a circuit continuity. While RH does indicate a continuity.

Is liquid going in the cartridge be the culprit or the RCA termination ( visually connections looks okay) or something else?

Any help will be greatly appreciated.
