I am not seeing anything that appears to be a missing component in or around Q521?
Or are you looking for that entire board?
The photograph does appear to be cut off some along the right side.
Are you able to take a couple more photographs showing both sides of the board and then circle or otherwise mark what is missing.
Not sure if applicable or not but I did find the following link:
