Ciao ragazzi ho questa scheda madre che non accende, aveva un corto sulla scheda madre, ho sostituito il chip PU402, ho fatto un piccolo passo in avanti, manca la tensione +1.2V_VDDQ coil PL502, se tolgo il ponte PJ501 la tensione +1.2V_VDDQ risulta presente, ho sostituito CPU e PU501 ma la tensione +1.2V_VDDQ non appare e il pc non accende.

MISURE:
PL502 - 260 Ohm - tensione 0.282 Mv, se tolgo il ponte PJ501 tensione 1.2 v.

se collego un cavo sul coil PL502 e inietto tensione 1.2 . con alimentatore da banco il pc accende e funziona regolarmente, apprezzo qualsiasi aiuto.
