1) To hopefully expand on what redk9258 mentioned, there is likely a voltage going to the power button tact switch that is sinked to ground when said switch pressed. You should be able to probe across the tact switch and look for some change in voltage when it is pressed. If there is no voltage to sink, see how far you can go back to find it.
2) Alcohol will get inside the mode switch. It may not be a complete solution but maybe enough of a procedure to see what, if anything, changes after you induce it.
Good luck!
