slt alflo, sur quelle sortie video as tu branché ta dreambox, l'AV1/3 est en RGB, l'AV2 en s-vidéo, si c'est sur l'AV2, essaie de switcher ta sortie en appuyant sur le bouton de couleur correspondant a la sortie ( il se peut que tu soit en s-video et que tu ne reçoive pas correctement le signal vidéo, il me semble que c'est le bouton vert ).
tiens moi au courant

salut voila j'ai eu la reponse au probleme c'est un probleme resident sur les marques panasonic et jvc je vous mets la reponse en anglais
It seems to be a Matsushita problem JVC/Panasonic.
I know Weare has an LG but maybe they shared something with Matsushita.
Pioneer Philips and others don't have this problem.
I thought I saw somewhere about a pin missing or something like that on these televisions
=MICHEL= did some tests and measurments but never could find the problem.

5 RGB Blue Ground
7 RGB Blue Signal (0.7Vpp 75 ohm)
9 RGB Green Ground
11 RGB Green Signal (0.7Vpp 75 ohm)
13 RGB Red Ground
15 RGB Red Signal (1Vpp 75 ohm)
17 Composite Video Ground
19 Composite Video Out (1Vpp 75 ohm)
20 Composite Video In (1Vpp 75 ohm)
On pins 19 and 20 please notice that a typical standard SCART cable the pins 19 and 20 are crossed with each other. The equipment which outputs RGB or composite video signal, the composite video is available on pin 19 at the female connector on the back of the signal sending equipment. The same signal is then available on the pin 20 at the other end of the SCART cable.
The composite video signal has amplitude of 1Vpp, which consists of 0.3Vpp composite sync signal plus 0.7Vpp picture signal.
