on and my tv says invalid format. I have switched the boxes from room to room and the box works on the other tvs but those boxes do not work on this tv. Appreciate any help. Cannot find daupport and there is no phone support
Try taking it to the TV where it works and set the "Display type" (Settings->Display type) to something other than what it's currently set to. Also, try unplugging the power from the TV where it doesn't work for several seconds and then plug it back in.
