If no lights are on can you say its the power supply or can you say its the power supply and/or the logic board? One would think testing the PS would be in good order before assuming its bad.

Unless damage is from a drop, pulled wire inside connector cable or other damage from severe action - most likely some goober, liquid or scratchy things went down the key sides. Here's the case with one still in damage mode and just undergoing operation.

Damage is asdfghj which seems interesting. Non working. The action taken is a hot bath jet spray down of the entire keyboard, usb ports and plug. Next, is a spray saturation of "contact" and electrical board cleaner across the sides of the damaged keys. A brisk shake out upside down, taps on the backside - all clears out most liquid. Now it is sitting in the sink with the corner in the drain hole.

If it works repairing the keys we're onto something. The topwater is fine if a contact spray gets used cause all the topwater will be spread out.
