Hey all im trying a fix my SONOS gen 1 which is powering up but consistently getting a white/orange led.  I went thru the whole network, register stuff nothing which then led me to do check on the actual board.  Looking at others issue with i saw common one for PSU was changing a blown R37 chip i then noticed on the videos beside R37 there is a R76 chip.  Nothing seems to be fried on my board but i do see mine is missing a R76 chip.

Trying to find out what type of chip is this is it the same as a R37 - resistance smd 1206 1 ohm 1R00 (R77)

It doesn't look like it ever had one, make sure you are comparing the same hardware revision boards.
