Re: Troubleshooting the SB II


 

Potential shorts across I2C signals on pins 4/5 on the Si chip, but that won't cause shorts,
just no communications.

Are you getting any voltage on U7.4 across C77?

Also, just want to verify that you're probing the voltages on the pins themselves
as opposed to the solder pads.  It looks like everything is soldered pretty well
but I've seen failures with lifted pins before.
