I have followed the lines on the printed circuit board and i have found r,g,b on tea5114 . 2 other lines on 7805 and lm317. However my knowledge ends here.

I have found a scheme. I see that the internal connector is connected to a pla and there are all cga signal. I think that using a pla these signals are all digital. Then all is connected to a TEA5114 that brings out r,g,b signals to a db9 connector. On db9 there are audio too. So the db9 is analog and can be connected to scart. I see r,g,b, 2 audio (connected toghether) sync, 5 volts line and 10 volts line, 1 ground.

How can i add picture from my mac?
