Post a picture of the back of the set with the connections so we can see exactly what goes where.
The TV could of course have a problem or misadjustment in the sync or tuner I suppose. Try adjusting the vertical or horizontal hold controls, usually on the back of the TV set.

I have tried turning the output and video levels up and down. It only affects to the noise of the image, but the two shades of grey still appear.

The test signal is working. I can see two vertical white lines over a black background.

The TV makes some beep sound when the modulator is on test mode, but no sound on normal mode.
In normal mode (not test) the TV shows the same image whether the DVD is connected (and on) or not. The DVD works as I tested it in a different TV.
I attach an image of the test signal.
