Possibly dirty or dead video recording head. If cleaning wont help then most likely repair is not cost effective. Save your video tape collection to digital format before unit expires.

Try a head cleaning cartridge.

Switching off DVD & disconnecting at mains cured the problem.

My Direct TV has no sound or picture but does show channel info at the top. Any help is appreciated.

Sounds like the scart lead is not in straight. Scart connectors have the audio pins at one end, and the video pins at the other. If the lead isn't in straight then you often get sound and no picture and vice versa.

Check the connection by pushing the scart lead in securely. (Both DVD and TV end of the lead)

Failing that could be a dodgy lead.
