Just got a new 722k from a 622. No issues with my Sony tv with the 622 remote but the 722k remote when i hit the source button only does channel, video 3 and PC vs. what my other remote 622 and dvd remote does. The other remotes do Component to HDMI. Some reason and i have tried all the codes it will not pick up switching to the component and HDMI? any suggestions? the tv is a sony xbr7 lcd.
