Hi Antonio,

In fact you are right it is either open circuit or read lower value. That resistor could have intermittent problem which is very rare but it did happenned.

Think of a single resistor in a complex circuit (series-parallel ckt) w/o disconnecting one leg, you will not have any resistance higher than it's value and if that happened it should be open. In my point , any good resistor on board will always read in it's value or lower and will not be read higher.

Oh yes, I agree with your words!
 
Otherwise you can check the electrolytic capacitors on board if you use the ESR meter.
