I have 820-476-a board . It powers up to black screen , fan spins fast and consumes .480ma - 500ma.
There is no 5v on lcd connector with or with screen attached.
No Enable signal on U8300 (checked for shorts)
U8330 and resistors checked (no EDP Panel PWR)
All S0 line seem to be present
ppbus_g3h is 12.6v
PPVCC_S0_CPU is 1.75v
What are the required conditions for EDP_PANEL_PWR to be present?.
Thanks for the input
