Title: Need photos of Tek 1000/2000 Series power supply
Post by: jogri on October 11, 2019, 02:14:25 pm
I am currently repairing a Tektronix TDS 1002C that has a bad power supply (bought it broken) and i need photos of the control IC (the one with the heatsink and the label "U1") (part number + orientation of the pins). It looks like this chip blew out (there are traces of brown gunk on the heatsink) and someone tried to fix it (badly). Some pads are missing and i am not sure if that person installed the right IC (right now it's a TOP244YN) and in the correct orientation, so i would appreciate if someone could send me pictures of a working board.

The board is an Emerson 7001574-J100 Rev 1H, and it looks like Tektronix installed that board on the TDS 1000 and 2000 series.
