new hdtv & HDMI

I had an old Sony tube tv connected via composite.  Got a new Visio tv.  Tried to connect using HDMI and got 'no signal'.  It works fine with composite. HDMI cable is a new GE high speed HDMI cable with ethernet.  I have three other older tvs which I don't want to change.  What am I doing wrong.

Some boxes won't pass an HDMI signal unless you're paying for HD service

adding... make sure you are connected to the 'out to TV' HDMI port. there are several on some of the set top boxes. Also check the port that the other end of the cable is plugged on the TV for its name and use the TV remote menu (or button) for input to select that port.

It's the type of box combined with the type of service the OP has

CEA-708 (digital closed captioning contained in the streams) is now required and only ouput on digital connectors. most new programming does not include any CEA-608 analog streams nor a conversion in recoding to 608 backwards compatible. The Digital stream must be 'on' at all times the box is in service mode and the 'provider' of the service will restrict the box to the subscriber's package. Note that HD MUST be delivered for local channels to all customers that use an HD capable TV at no extra charge to the customer for HD services.
