I am totally perplexed. I have an HR24 in a room with a Norcent LT3222 television. When I use the on screen menu set up the remote code for the TV, a screen comes up and asks you to press vol+ to check if it works. When I do this, the volume works. Then I press "it worked" to go back to normal operation. When I do so, the remote no longer controls volume. I have tried moving the switch on the top to TV, but still nothing. The remote is the RC-65RX. I would appreciate any feedback. Thanks.
