Hi dear people of this blog. I have a DSO 6054A, which requires your help. The scope pass all the tests but it doesn't read any signal at BNC on all 4 channels. I suspect it is a broken regulator/powersupply issue. Unfortunately the part number on this regulator is unreadable. I am attaching the picture and hoping someone can identify the part number. The silkscreen reference is U3505 and U3507.
