Xpeed-Lx1 scart error

[orion13]

I just bought a LX1 Xpeed receiver. As I have an older TV that doesn't have HDMI, I use a scart cable.
After install the firmware, on the boot, the TV picture is distorted. I can't see anything. (I think that is on error in RGB color mode)
It is a manufacturing defect of the receiver?
I have installed the latest firmware.
The TV and scart cable works well in RGB mode with a Dereambox 500s receiver and a MK-Digital XP-1000.
