Hello solved the problem of Flexgate by replacing lcd, but it does not have backlight, here are some measurements: PPVIN_S0SW_LCDBKLT_F = 13V PPVIN_S0SW_LCDBKLT =12V EDP_BKLT_EN= 0v BUF_EDP_PANEL_PWR_EN= 3.40v EDP_PANEL_PWR_EN= 3.10v PANEL_P3V3_EN_DLY= 3.29v

Hello I checked U9310 all the output voltages are 0V I only get 1.5V on PP3V3_SSD_LIM

I have this card that works perfectly the only thing that in the Monterey installation once you enter the password, it tells me that it can't install an update and doesn't keep me

Hello maybe a stupid question, this card can work without a cd3215, or they want you all 4, I've never fixed such a card
