I assume it's either a bent piece of motherboard/sub-board, that is not fitted properly, or (more likely) it could be a bad/dirty power-switch!
When it cools off, it 'breaks' a connection, which does not seem to be needed for running it.
By heating it up with a hairdryer, this piece will either bend properly or straighten properly, and make the proper connection again, so it can start.

Where exactly do you direct the heat to get it going?
