QMX won¡¯t power up


 

I can¡¯t get my newly finished QMX Rev 1 to power up. When I push the power on button, I do not get 3.3v from IC101. If I power PCB#2 from an external supply and float LIN-REG-EN, I get 3.3v from IC101. LIN-REG-EN on the main board in 35 ohms to ground. I can¡¯t find any shorts on the board. I am suspecting the microprocessor is toast. I¡¯m thinking of floating LIN-REG-EN going to PCB#2. Ideas appreciated.?
