Question about Polk Audio PSW350 Subwoofer
Brown resin seeme to be on the cicuit board by LINE IN and the LFE IN.
Should I replace the board
The brown resin is glue that changed color due to heat and age. Rarely have I seen it cause problems. So unless you are having problems, No.

It describes a way to possibly fix your remote or at least prove it works or doesn't.
Find new or replacement remotes:
or eBay: search for "(model) remotes", check the 'include description' box. Usually cheaper than the vendors.
