: Avoid standard VGA cables. While they share the same DB15 physical connector, standard VGA cables often lack the necessary internal wire count or shielding, which can lead to high-pitched whining or failure to power the pod. Internal Board Issues : If the pod fails to turn on, users often check the LM217 (LM317)
