820-2327-a doesnt turn on, nothing on 3v3s5, u7200 has nothing on entrip (pin 6) for 3v3s5, resistor on entrip line is (r7272), problem is the schematic shows this resistor to be 57.6k, im getting a reading of 75k, BUT on the same model board that is working, on that same resistor i get a reading of just 3.1 ohms,

What i think I know: that pin 6 on u7200 (3V3S5_ENTRIP) is an enable signal telling u7200 to turn on pp3v3_s5_reg.... is this correct?
what i dont understand is if the resistor on that entrip line is supposed to be 57.6k, and on my bad board its 75K, yet on a good board its only 3.1 ohm....
is the schematic wrong or am i missing something serious?
*I'm new at this and I havent yet successfully fixed a board, I've watched a shitton of Louis's videos and am still learning...
