Pin 27 on U7000 is a direct connection to Pin 2 of R6991 from what I can tell.
As I'm not getting anything on R6991 I wanted to look at U7000 to see if it is even getting the voltages it needs, but I'm not good enough at understanding the schematic just yet.
Could someone better than me let me know what voltages I need around U7000 to feed U7000 please. That way I can see if it needs replacing or its something feeding it thats is the issue.
