What about ldo's? 14 and 15 pins on pu2. ec_on is signal FROM pu2 (on scheme) enable signals for +3/5valw is entrip1/2, for RT8243A its from-ic signals, connected to gnd with 100k resistors (see datasheet), so if ldo's are in normal values and no shorts on +3/5valw - try to change the pu2. and what about power key? signals on jpwr1?
