Cable TV won't work (but other HDMI sources do)

Post by Johnpaulr » Sun May 28, 2017 11:17 pm

Hi,

Hoping someone might be able to help me out. I have an old HLP5085W Samsung DLP 50". The TV works fine, except for the oddest thing. I can use a Wii U, Xbox 360, Xbox 1 all without issue through HDMI. However my Comcast Xfinity doesn't! The box works fine on other TVs, checked cables too. When I turn the cable box on it says "Setting up, this might take a few minutes" and then goes black. If I take the cable out the TV and put it into another TV the box is fine and TV is broadcasting! The issue seems to be that when the box is about to broadcast something between the TV and Box cause it to not go through.

Has anyone ever seen this? Is the a TV chip or something the box is looking for that the TV doesn't have?

I guess its maybe a problem with copy protection (HDCP, ...) or the image resolution.
