Facing TV Problems? Ask a TV Technician.
Hi , I`m JackPerhaps I can help you with this problem , let me know when you`re ready ?
Can you see this reply ?
There should be no reason why the dvd player would not work anymore , send me a reply and we`ll figure this
Could be that your hdmi connection to the dvd got temporarily disconnected when you replaced the cables for the dish box .
Double check to make sure that cable is connected securely at both ends .
By the way , you should ask direct tv if the channels you could not receive are broadcasted in 4K ?
That's the only way your tv would not be compatible with that HDCP (protect scheme) format ,otherwise there would be a problem with their box , not the tv .
In any case ,glad you got thing worked out and let me know if you need help or have questions later on .
