It depends on how much heat it’s actually making, but maybe if the factory job done was crappy. It’s probably thermal adhesive though which is harder to remove.
I see corrosion/deposits by those two leds and the hdmi… rinse it with vinegar, then DI water, then 90% alcohol. See if that doesn’t bring it back to life once it’s fully dry. You also might have to reflow the solder though.
