I have a 2221A + 2230(s) & 2232(s).
I think that the are very few, if any differences, within the power supply
sections of these scopes.
There is a lot of very good material available in the archives about
servicing the PS in these and the 2213(A) 2215(A).
If they are dead, it's probably the second place to look anyway.
The first place is the voltage test points.
A short delay after pushing in the power button is normal on all of the
above scopes.
There should not be much difference in the power supply because those
all use the same main board which includes the power supply and analog
signal paths from the inputs to the CRT. Some of the non-DSO 22xx
series like the 2225A and I would guess the 2213A and 2215A also use
the same main board.
