Sounds like the issue is with the set top box of your cable or direct tv provider. Please swap that receiver for the equivalent or a more updated version.If the problem persists. Verify that all inputs on television is correct. It should match. Output of source( digital receiver,dvd player) to Input( television ). Make sure all is secure. Good luck

Noise and horizontal line


Very easy Fix, The problem is the cable box is not grounded properly. (not your fault) Go to the Local store and get a Plug adapter, just to change the TV plug that goes into the wall or surge protector from 3 to 2. Trust me on this....

Lines across screen when using View On Demand channels


Could be a couple of things causing this.

1) Obvious, but I assume that you subscribe to these services, because otherwise it could be the encryption.

2) Make sure that you have the set-top box connected directly to the TV, and not through an external recorder (VCR, DVD etc)
This would be a problem if the services were copy protected in the same way DVDs are.


You could also check the settings on the set-topbox. Make sure the video output is set to RGB.
