Did you visually check all resistors as well or test them all?
Does measuring resistance change with polarity?
If my memory serves me right, I did not check for any faulty resistors, I inspected the board visually and I noticed that a discolored resistor had gone up in value, by replacing it the problem was gone.
It does not matter where you put the multimeter probes when measuring resistance, readings should not change.
good luck !
