ALWAYS start with the "easy" things 1st. Is the AC outlet on the wall working properly? Is the "wall-wart" power supply working correctly? If no defect is found, check the DC power jack located on the rear of the keyboard. Does it seem to be loose or does moving the power supply jack up/down cause any change? New wall-wart power supplies can be purchased from Radio Shack and usually at a lower price than the original factory replacements.

At this point, you need to take it to the shop. There are too many possibilities to get it figured out without it being in hand.

Rust is an indication that the unit has water or moisture damage. The keyboard should power up using batteries or the adapter. Is the adapter is one supplied by Casio?

If this fails, I suggest returning the Casio for a replacement.

I would check your fingering... You MAY be late in hitting a particular note and the using auto chord... this can cause the problem. Another thing is if notes are hit with different velocity that can affect the sound. Sometimes certain voices have VELOCITY switching which actually changes the voice depending on the velocity you hit a note.

I would say you could download one from the Casio web site

Need to know more details about the problem: What is it doing (or not doing) that needs fixed? When did it start? How long has it been doing (or not doing) the problem?
