Slot loaders are very prone to heat-related death. Make sure you have the front foot extended to raise the bottom and allow cool air to enter. It fold out from the underside near the front. I would also advise raising the rear with a small block of wood - this made a significant difference to internal temps on mine, as it both improves the air intake from the bottom and raises the top vent closer to the top of the unit. It also helps with the viewing angle.
