Had some problems and put the assembling aside for some time..
I've assembled the scheme completely (only SCART misses for now, as I don't need it), but still get some problems - when I switch it on, it flashes 3 times in RGB each, then starts changing colours slowly (rainbow) - as I assume, it's a test mode. But when I shorten the S2 pins for a moment, then it goes red and doesn't switch to analyzer mode anymore. The VGA from videocard is connected, and video-out enabled too.
Any suggestions? Thanks in advance!
- that's how it looks and works (or not works)
