My cable/satellite provider offers 3D channels, but I can't see them on my TV. What's wrong?  

First, be sure that you've connected the box to your TV via HDMI — it's the only type of connection cable that can carry 3D video signals.

Next, check that both your cable box and 3D TV are in 3D viewing mode. Most new cable boxes will already come with 3D enabled. If yours wasn't installed very recently, you may need to turn it on manually. Depending on your cable box, you may need to manually switch back to 2D mode for 2D viewing, though some newer models can handle this automatically.

Your 3D TV should be set to "Auto" to allow both 2D and 3D viewing; this mode should also work with your cable box.

Finally, you may want to contact your cable/satellite provider and double-check that the 3D channels are part of your programming package (not all channels are 3D). They may not necessarily be included with what you currently subscribe to. And if our troubleshooting tips haven't helped, hopefully they can get you up and running.
