Indeed so. As for troubleshooting switching power supplies --
the problem is that many of the manufacturers treat the schematics as
proprietary information, and a typical multi-voltage switching power
supply tends to be sufficiently complex so troubleshooting without
schematics is quite difficult. Much cheaper to find a replacement in
most cases.

What DoN said. Switchers are NOT easy to fix. You can't measure voltages
and look for the ones askew; they all are if it's bad. (Chicken & egg)
You can't blindly replace parts; the caps must have good ESR values,
chances are the semicomnductors have house numbers, etc.

None of this matters if you are working at Delta with 100 Model 567's
a week going by; THEN you know what is going on. But Reddy Milliwatt
is just guessing.

Replace it.
