This board is not liquide damage. I found short smc that I replaced and now I have green light and ppbus at 12.54V
3V estables but 5V pulsing each 6 seg. CPU core pulsing too. Could be bad donor-SMC or something else?
Other guy replaced the isl6259 but he burnt both mosfets someway. So, I think in some time ppbus recived 20V directly from ac adapter if upper mosfet was burnt firstly.
Can that burn some component on ppbus?
