Chris, The 4.92 volts on U6-30 is good - that was the one you reported as zero or very low, and is what prompted me to ask you to measure the resistances. I think you had an incorrect resistance reading from RP4 pin 5 to U6 pin 30. There should be nothing between those points but PC traces, so you might want to check again. Re-check the voltage at U6-30 after restoring R1 - if it is still near 5 volts, then all is OK.
