I'm pretty sure the U2 chip is just an audio amp and isnt needed. I think all the capacitors are just for filtering or something but they arent needed either.
Also, before I pull of the caps and trim the board I tried to test the video out that I will use, so I connected that to the AV cable and the image was very bright, is that normal? When I remove those caps and other stuff the image will get normal again?
