Facing TV Problems? Ask a TV Technician.
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, bear with us; re-confirm and post back with the complete model number of the TV. Additionally, please describe how the DMR-BW780 is connected to the TV using what kind of cable(s).
And the TV's model number please?
With the connecting cables, possibilities are:
Have you inspected & checked or better yet replaced the connecting cable(s)?
Is it only the TV broadcasts / programs that no longer show? ...or even when attempting to play a movie Blu-ray / DVD disc?
