Sunlight damage and electronics

I'm curious about what people think about the following. I was supposed to be buying a Neo Geo Arcade cartridge from a dealer I trust. Unfortuantly just before we finalized the deal the cart quite working on him. The only thing he can think of is that he was gone for a week with the blinds open and the California sun shinning down on the cart. A Neo Geo MVS cart is typically two circuit boards in a large black plastic case (larger than a VHS tape). What I'm wondering is did the heat melt the solder, or could it have baked some components.
