I have a Panasonic tx-32lxd60 t v and Panasonic d v d recorder dmr-ex75eb, they have worked perfectly for 6 years. Now the recorder keeps showing no signal check aerial. I have checked the aerial and rerun the auto setup but still no stations, all other t v s are working and come off the same aerial including the one running through the recorder. Is the recorder u s or I'm I missing doing something?
