I tried to Trace the +3VALW all remove the jumper connections that flows the +3VALW line but same got 70 ohms I already remocve the PJ401 from the PL402 coil. Hope some can guide me what to check next.. home my cpu is not dead or pch maybe?
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

you separated the line +3VALW from +3VALW. can you measure with respect to mass the +3VALWP line, what value does your multimeter mark in diode mode?

Thanks for the help the pch is already dead confirm after removing the pch chip all shorts gone,
Ive learned that if you test the pin8 of the Bio chip it can be easly conclude that shorted pch , great experience.
