Hello everyone .....

I have a problem with the screen on the BMW e39.Navigation computer dont work for some time now .... TV module is worked with
and little change in appearance of images on the screen.All options worked except navigation which is not featured in menu.Now,
I have a problem that the screen has a backlight,from time to time flickering white lines and it is
all.It is very interesting that when you pull out the fuse number 47 or 57 I'm not quite sure and again after I return after
some time image appears briefly, but only briefly until the door shut, or simply during the
drive disappears again ....
Does anyone knows what would that be a problem?
Thanks in Advanced
