No LED lights installed. Not sure what could have caused this other than the set just getting old.
This unit has three sets of component inputs and uses two of them. Doing a little research, I can't seem to find a unit that has more than one set of component inputs. Not sure what the two sets of wires go to, as I only have one DVD/CD player and the Winegard switch unit. I use an HDMI cable for my DISH sat receiver that bypasses the switch unit. I do have a rear DVD/CD unit for the rear TV, but I don't think they are connected together.
My component cabinet is stuffed with the DVD/CD player, DISH receiver, and the Winegard switch unit...so trying to get in back of them to trace the wires is impossible without have to remove both the DISH receiver and the switch unit.
We spend our summers here in Oregon, so probably will wait until we get home in October before trying to figure this out. Hope the existing TV lasts that long.
