the fan is speeding very high.
I hope this "How to" collection will help our members. I will possibly modify this post in time, if updates available. Trigger SMC_ONOFF_L (PMU_ONOFF_L): It reffers to simulate power button function, when the keyboard is not connected. We need to do this when we work with the board...

Use an USB-C hub with HDMI output to connect external monitor/TV.
Ok. I had to change the sound ic again. The fan has stopped speeding. And the fan now twitches every 1 minutes . And all the voltages are present now.
1v8G3S is present
3v3G3S is present.
5v G3S is present.
Non of the s5 rails are present.
but u8220 is getting hot intermittently I got that from the thermal camera. The fan twitches every 1 minutes
fan will not spin. It will just twitch. It will just move a bit and stop every 2 seconds.
This morning trying to check it again I mistakenly bridged two voltage lines together and there was a spike while trying to troubleshoot and the fan started running fast again.
