#1 HP 14-CK (GRANGER 6050A2977601 MB A02) - Power on, No Display

Hello
I have a HP 14-CK (GRANGER 6050A2977601 MB A02) laptop. There was a small amount of liquid damage in the area circled in yellow on the picture, this was causing a short on the 19v line. I changed this component and also the dual mosfet below it and this cleared the short and the board was able to power on again. But it will power on with no display and will just hang and consumes around 0.32mA on the powr supply.

I have all voltages on the coils (see picture). The coil to the right of the Hybrid CPU has 0v but i compared this to a working board and on a working board it also has 0v?
I have programmed a new BIOS file and still no change. Can anybody help diagnose further.
Thank you.
