The 3.3 v reg (little three legged part with 3.3v near it on the left side of the pic chip) and some of the pic chip legs look a little off the pad and are kinda dry like they had little solder paste on them.
All Done , I get continuity from PIC pins Bottom 2,3,4,left to right to THE U2,s RIGHT to LEft second pin down on the left hand side. RJ the only R<G<B I see is above the R7 I check continuity here also with no results but did get continuity as you describe on the U2,s am I missing something I do not see the BIG R>G>B that you refer to
