Hi, I own three boxes, two of the boxes are hooked up to two similar TV's, in the living room I have the Pioneer Pro 151FD and in my bedroom I have the Pioneer Pro 110FD, I have programmed both remotes for each TV to be used, the remote in my bedroom shuts off and turns on the TV and also controls the volume, the remote in my living room only turns the tv on and off, but does not control the volume, the volume control does not work, is there a fix for this, I am perplexed.
