Bringing up this topic.
I dunno, that have this been discussed on anywhere, but I took a picture from my SCART-cable for PS1:
I've wondered for some while, that is it supposed to be like that, that it doesn't have all the pins on it ? It's official Sony cable thou, but since it's black, I suspect that it might be for PS2 as well. Someone propably could explain more about this or know more. On the SCART-head, there is this sort of PCB:
The reason why I'm asking this is that I just recently hooked my PS1 back to my TV, 40 inch Sony LCD. And I noticed, that there was some small noise on the picture, when I looked closely. So I thought, that is it either bad cable or something about C Sync, that I've read about.
EDIT: I totally forgot about this very bad issue:

Either the cable is wrong one or the TV just doesn't quite accept the signal properly. TV is Sony's LCD from around 2009, Bravia-series one. Same issue happen when the game starts loading up. On here, I just resetted the console, but it also does that same thing, when pressing the power button as well. Strangely, after some while, the problem isn't anymore so bad, but still occurs.
I suspect, that the issue is on the TV, because when playing the games, there is some places in game menus, where the picture is not properly centered (gameplay is fine, picture is centered properly on that). So I perhaps could obtain and try those SCART to HDMI-converters.
