I have to check and see if the backplate does in fact contact that chip. There is no thermal pad on it however.


Look just above that chip in the Pic silkscreened on the PCB - its labelled U601.
I do understand that U601 is the VT1165, but it isn't sinked, the back plate doesn't touch it, and there is no airflow whatsoever in that area, none, nada, zip
