Do they fix game consoles also?

Not to my knowledge.

Great Escape most likely is not permitted to make repairs on the game consoles or other equipment. There would be no way to draw the line between what can and needs to be fixed from item to item. Then, there would be a whole part ordering inventory that needs to be taken care of constantly. They do not have the staff or income to cover that, most likely. - source, ex - technician -

They test consoles when you try to trade them in. But they dont fix them.
