Pwr supply is similar in all: Tektronix 2213/2215/2213A. bama.sbc.edu
as a starting point for free download.

check postings of Jim Yanik and others in sci.electronics.* for this
type of fault.

This type of Tektronix scope has an SMPS with a primary pre-req
circuit. Faults, repair hints and corrections are often described in
e.g. sci.electronics.repair and similar.

Most often: TL597 IC blown, FET blown, fast recorvery diode blown.
