Hey guys. I got a 820-00281 that was liquid damaged and said to not turn on. When I tested it the board did boot, but only display's image to an external monitor and was showing a flashing folder icon. I was able to see the SSD in disk utility so I think it just does not have an OS installed on it. I booted with a test hard drive and it booted into the OS fine but only showed image on external monitor. USB activity was working so I replaced U9850 to see if that would fix the issue. Now the board does not seem to boot fully anymore. I do not get image on internal or external monitor anymore and caps lock does not respond. The board is showing that it is using 19.9v and 1.2 amps, both the CPU and GPU are getting warm and the fans are spinning normally. I checked all my S0 rails and they all appear to be present so i'm not sure what could be wrong. I replaced U9850 a second time to see if there was any change but it is the same. Here are some of the values I got for my S0 rails.
PPVCCIO_S0_CPU - 0.963v
PPVCCGT_S0_CPU - 0v (Also shows 0v on a good board)
