If the TV is backed up against the corner of a wall with a small gap between the back of the TV and the wall, is it safe to run the TV without the back on AND without the high voltage cage cover removed? X-rays travel in a straight line, so the x-rays that would have been blocked by the cover will just hit the wall behind the TV. No pets or children would be in the room either. The reason why I'd consider doing this is because it would help with cooling the inside of the TV, especially the flyback transformer.
