DSO 6054A broken LDO

Hi dear folks of this forum. I need your help in identifying one broken part on the DSO 6054A. I am attaching a picture of the part along with the ref number. Also the scope doesn't read any signal on all 4 channels. I think U3505 is a +12V LDO and U3507 is a 3.3V LDO but need to confirm before I replace them.

U3505 and U3507 ??

 

Thanks'

Eric
