could you supply us with the remote model... probably the rc122, but could be any of a dozen, and the codes are likely different for each
try the following,
press AUX and ok/sel until lights on remote blink twice
enter code 3479
lights on remote should blink 4 times
test vol+ vol- and mute
if this works, your remote should be able to control your device, the next step if this works is to put the remote in "cable commmand mode" by pressing cable, and testing the vol+ and vol- buttons again
if the AUX works but in CBL does not, you will need to program the remote to use AUX as the primary audio solution
Setting Volume Control
to Audio Device:
1.Press and hold OK/SEL and CBL
and until all device keys
2. Press 993 . The CBL light
key blinks twice.
3. Press the AUX key. All device
keys blink three times.
at this point the AUX key should be programmed for the audio...assuming we have the correct code for the Vizio sound bar
Note: You can set Volume
Control back to TV. Follow the
same process as mentioned
above but just press the TV
key in Step 3.
you can also try the code 1230 for the AUX code
I've tried that and can finally get the remote to do the volume on the soundbar. However, I then can't get the TV to turn on/off with hitting TV then power (or through the all device power method).
what brand is the tv, needs to be reprogrammed under the TV setting, then we can program all devices to turn on and off using just the power button
