			1. It maybe that you have just an AV lead that uses a SCART connector, rather than an RGB lead. I've heard that those exist. 2. The JP1 mod doesn't work with all types of Saturns. It could be that it doesn't work with yours. Maybe try the other 50/60Hz mod instead.

			3. Make sure your TV is not trying to display an S-video picture.

No, because the same leads are used. Note that if the AV1 socket on your TV doesn't accept S-video this is not the problem. The cable is supposed to signal what mode is used but the feature doesn't always work as it should. Selecting the input mode manually from the TV set usually fixes the problem.

			i can't change it manuel. 1 have use all my rgb-stuff(psx,dc,xbox...) on av1, because av2 have not rgb.(if i connect it on av2, that works without rgb) i think i buy me a new rgb-lead. what can i do for the 50-60hz mod. I mod it exactly the same as in the picture with a switch on-off. big boss

			Big Boss don't buy another lead, I have the exact same problem as you. My 28" Sanyo TV has 2 scart sockets the first is RGB compatible the 2nd is just AV, when I plug my saturn into the RGB socket I get a black screen with sound, when I plug it into the 2nd AV socket I get full picture and sound but without the obvious crispness of RGB mode. I went and bought another RGB lead from a different source but got exactly the same problem, gonna go try fiddling about with the input mode on my tv like antime suggested. I also have performed the same 50/60hz switch mod, as well as added a mod chip and a country mod switch.

			Open your lead at the SCART end and check how/if pins 8 and 16 are connected. AFAIK pin 16 should be 1-3V for RGB and pin 8 may have to be 9.5-12V. While you're at it, check how the rest of the pins are connected.

			My 50/60hz mod works fine, as does my country mod, I should have mentioned I have a model 2 saturn not a model 1 don't know if that makes a difference. I tried messing around with the input mode on my tv I could select between S-Video and Video both would go black but still have sound, gonna open up the scart lead tonight and check pin 16 and pin 8.

			If the picture goes black but you have sound the problem almost certainly lies with pin 16. See here....

			BINGO Thanks a lot for that antime that was exactly the problem, finally RGB quality for my saturn.
