Signal problem with an LCD Samsung

[Tivoman44]

My father is having a problem with his TV connection, not sure if it is a TV problem or a TWC problem.  It is a Samsung LCD LN-4665F.  It has Digital cable from TWC, scientific Atlantic Box, it is a little older from 2007, it is an HD8300, NOT a newer HDC8300.  TWC gave them componant cables, eventually an HDMI cable was added instead.  At one point a message came across saying how the cable was not supported.  Off and on it happens when the picture on the TV does not work but the sound does, and you flip channels and hear the sound change.  Then the picture works out of the blue.  Has anyone ever heard of this.  Is this a TV problem or TWC problem.  Does it need a new box, a new HDMI, or to go back to componant cables?  I remember reading something abou tan HD8300 not being the same as a HDC8300.

When you have service problems call TWC  They do not charge you for it. They are the best ones to diagnose the problem.

Sounds like it's the HDCP or high def content protection, which can be linked to either a bad hdmi port on either the cable box or the tv or a bad hdmi cable.  First try the hdmi cable in a different port on the tv, also if you can try a different hdmi cable.  If that doesn't work either go to twc and swap boxes which doesn't cost anything or switch back to component.  If you swap boxes and it still doesn't work even with a new hdmi cable then it's something wrong with the tv.
