Re: ID BIOS chip HP 24-xa0024 DA0N76MB6E0 Rev E

I have this hp all in one pc, issue no power on at all, fan never spins, when i connect the power cord it flashes 1 time and the power supply shows 0.018 power consumption. but not power on. If i disconnect a cable that goes to the lcd (not the flex cable) then it will flash 7 times but no power on. power button is getting its 3.2v and seems to be working.
I HAD TRIED EVERYTHING BASIC - INTERNAL BATT, SHORTING BIOS- TESTED VOLTAGES CAN'T FIND A SHORT.
I proceed and downloaded the bios from hp confirmed is the same bios...
