Ha-ha-ha.

That was about getting a scematics. Sorry, could not contain myself.
In short -- you will not be able to get one.

Now, to you power supply. Measure the outputs. If you get all the readings,
PS is OK. You can also try to measure outputs with load disconnected.

If PS is bad and nothing is obviously blown (check chopper transistor and
secondary diodes), then problem is likely to be one of the electrolitic
capacitors. Usually, you can see the bulge on top of a bad one. If you have
ESR meter, check them all.
