|
On my grundig P40-440 CUC4400, the tuner signal sometimes disapearjavascript:emoticon(' ') Evil or Very Mad. If it happens, than a VCR tuner on the scart will work ok (Besides,It always do). So it means, there is an antenna signal always available, but interupted in the TV. Any ideas where to look at . I do have the scematics found on this site.  |
