Man, that's a huge find. I totally get what @hollym82 means about the wallet getting lighter, but seeing the heat spot is proof you just can't argue with. A multimeter tells you part of the story, but that thermal image shows you the exact problem in a way numbers on a screen never could. It stops being a guessing game and becomes a sure thing. For tricky faults like that, it seems like the visual proof is worth the cost just to save the headache.

What's the end goal if they're not selling games to be played?

My sister had the same journey with that ending, took her three rewatches to get it.
