Ravi,
I have swapped the power cords with my TDS360. The issue seems to be the LVPS A25 board. Power is getting to the board, but no low voltage rails come out the other end. There are no schematics for the SMPS, which makes things even more difficult. The diagnostic sections of the manuals are not very impressive, especially when compared with older TEKTRONIX manuals. The lack of any schematics is doubly frustrating.
