PCM means it thinks you have a digital cable hooked between the TV and Bose (most TV's don't have digital audio outs...). You will have to use the menus to change the TV input to use the ANALOG cables (assuming thats what you're using...).

Have a Bose 3-2-1 Series III. When I put in a DVD, I get sound through the Bose but no picture on my Pioneer TV. This is the second time it has happened. The first time it, we managed to get it going...

Here are 3 things to try and an if all else fails at the end.

1) Make sure the TV is set to the correct Video Input to see the video from DVDs on the Bose system.
• Make sure a DVD is in the disc tray.
• If the TV is connected to the media center using the HDMI cable:
Switch from one Video Input to another and then back to the original input.

2) Turn everything off, then:
Turn on the TV and set the TV Video Input for the Bose system video.
Turn on the Bose system and press DVD.

3) Turn off both the TV and the Bose system and then:
Unplug the HDMI cable from both ends.
Disconnect the power cables from both your TV and the Bose 321 system.
Re-connect power to the TV and to the Bose 321 system.
When the Bose 321 system startup message disappears from the display,
re-connect the HDMI cable to the TV then Bose 321 system.
Turn on the TV first, then turn on the Bose 321 system.

If all the above fail then disconnect the HDMI cable that connects the TV to the Bose 321 system and reconnect the two using a Component cable, an S-Video cable, or the Composite cable provided with the system.

Hi! It would just be easy. Just prepare RCA cables and connect the cables to the tv and satellite receiver. Link the TV and satellite audio output to the BOSE audio input. Good luck and have a good one!

Communicating with your tv message on bose 321 series 2

Well, it seems that this may be a common issue with this BOSE unit. My 321 GSIII was working fine as well for about a week. After a full frustrating day of switching, disconnecting, reconnecting cables and resetting the unit and TV several times, I was forced to call the BOSE Technical. They tried to help with the situation over the phone by directing me to do just about everything I did before I ever called them. After about an hour of their unsuccessful help, they left me in saying that I will now have to run Composite cables because my TV will not connect for some reason through HDMI even though it was working for a short time. AHHHHH...I custom prepared the walls in my new office to accommodate non-exposed cables and wires and now BOSE is saying to expose Composite cables. Tomorrow, I am going to connect the Composite cables to confirm if the 321 will now work that way (for curiousty). I will then call BOSE back and demand a replacement unit. I will keep all in the loop with my progress of this situation.

I had my older bose 321 hooked up through vcr and sounded great. Then hooked it up through directv receiver and sounded better. then switched from direct to comcast and hooked the bose up throught the comcast hd receiver and the volume is aweful. same deal, have to crank it up high. Since the stereo built into the tv sounds so much better I disconnected the bose and am going to sell it.

PCM 2.0

I had the same problem with my 321 system. The fix is in the cable box settings. You want to change the Digital Out on the cable choices were HDMI....Dolby Digital..and None. Choose Dolby Digital and it will show up on your Bose 321 display. I also have my cable box connected to my bose system via optical digital cable...and a digital coaxel cable from my dvr to my bose. Change that output setting on my cable box took care of the PCM 2.0 problem for me.
