I have a similar situation and also want to ask for advice. A1708 board 820-00840, no gong no image. The trackpad responds, the fan first turns on for 5-10 seconds, then turns off. If measurements are taken on the board without connecting any cables and SSD, all the necessary voltages appear, with the exception of the graphics power phases PPVCCGT_S0G and PPVIN_S0SW_LCDBKLT. Current consumption during autostar of the board first increases to about 0.5A, then drops and stabilizes at 0.234-0.244A, ALL_SYS_PWRGD - 3.21V, there is short activity on spi flash for about 3.5 - 3.7 seconds. That's all....
