It was working fine, then didn't work? This suggests a possible change in
reception conditions. You should definitely swap the sets, as suggested.
However...
You've lost SD reception (SD being 625-line PAL), but not HD, right? As far
as I know, SD and HD use separate tuners. (I think.) I could be that the SD
tuner has gone out.
