came dead
3v42 g3h missing
when heating around u7090
outs 3v42 g3h and board works fine but after some time 3v42 g3h drops to 1.8 something and board shuts off
changed u7090 ,L7095,R7095,R7096,C7094,C7095
but result is same after some time drops 3v42g3h

I changed resistor by equation vout=1.25*(1+ra/rb)
