DVD player "No video signal"
I have these two devices:
DVDR 3450H HDD & DVD recorder / player
DVD player is connected via scart cable.
At the beginning, when I try to play any dvd-s or recorded tv shows, the picture is very good, but after some time it starts loosing the signal. So the screen goes black for a second or so and then the video appears again. This continues for some time until the screen goes black and the white text is displayed "No video signal".
I really need some help please:(
