Amiga 1200 repair - Video problem

I'm here taking a look at an A1200 motherboard that suffers from two problems, both related to the video output. One problem is that I'm not getting any picture from the RGB output. The other problem is that even though I am getting a picture from the composite video output, the picture that is coming out from there is distorted in some weird way.
