I have tried everything it is in dual mode. Shared view disabled. Set to the correct channel. If I run RCA TV2 works fine. I have even run a coax straight from TV2 out to TV2 with the result. Box has been replaced. Any help would be useful
The receiver output is set on the Local Channels screen and can be off-air or cable, some tv's will scan what is set. If receiver is set to off-air, tv should be set to antenna. If the tv is set to cable and tv1 is on a low channel number while tv2 is on a higher channel number the tv will pick up tv1 but not tv2.
