Quote from: albino_vulpix on April 11, 2009, 11:11:39 AMMy input on the netting issue: I don't think it's related to cable quality, but with the signals themselves. The patterns seem too coherent to be interference.
Quote from: Link83 on April 11, 2009, 06:50:54 AMTo be honest I have no idea what causes the dots/netting/masking. When I used an S-Video cable with the components still missing with my PAL N64 on my CRT TV I just got a washed-out overbright picture, no dots or netting as far as I can remember.
QuoteIf you see a mesh pattern in S-Video, it's because the cable itself is not actually passing Chroma/Luminance into the S-Video plug. They're passing COMPOSITE on the Luminance pin instead. If you were to take a multimeter to the Composite plug and to one of the top pins of the S-Video plug(not too sure which), you'd hear your multimeter beep, indicating there's a connection between the Luminance pin on the S-Video connector and Composite. A lot of dual Composite/S-Video cables are like this(I was burned by one of those cables, but it was for the Dreamcast), though my MadCatz Super NES/Nintendo 64/GameCube/PlayStation/Xbox dual Composite/S-Video cable actually passes true S-Video into the S-Video connector(I can confirm this as I don't get any video when using the S-Video plug on my A/V modded Top-Loader NES, AV Famicom or Super Famicom Jr., none of which output S-Video), however on my Super NES, it induces some video noise in the audio signal which is typically almost inaudible on the Super NES when I use standard Nintendo Composite cables.

Quote from: Shadow_Zero on July 10, 2013, 01:13:50 AMMy tv's support s-video. It was in colour before the mod. And for the record, composite is still in colour.
QuoteFrom my personal experience with this same problem, all you have to do is use a 75ohm resistor to bridge Y(luma) and ground. Do not bridge crhoma!Since there doesn't seem to be PAL s-video cables (all s-video cables I have bought, even in local stores, were NTSC style), you can probably just solder it directly on the console and save your cable's original form so it also works on ntsc machines.
Quote from: Shadow_Zero on August 19, 2013, 08:51:52 PMOk, tried to fix it this weekend with my mate, but resoldering everything resulted in no s-video image at all (composite was fine). Wiring it directly again and it worked again. Trying this mod again without the 2 resistors had better image (color) quality but resulted in a lot of interference lines.So what's the deal here. Do I have an other PAL revision or something?I found an other source with an other mod I could try:http://www.assemblergames.com/forums/showthread.php?12169-PAL-N64-s-video-problem&p=263540&viewfull=1#post263540Radorn wrote:QuoteFrom my personal experience with this same problem, all you have to do is use a 75ohm resistor to bridge Y(luma) and ground.

Quote from: AlmostOriginal on February 28, 2014, 12:26:57 PMHey no problem! The Nintendo 64 S-video mod is really a mind twister. I felt bad that nobody seemed to help you. I was in the same boat when i had problems with my system. Well let see, one problem that i had was i got no S-video picture. Problem? I had the 75 ohm resistors connected to ground but no ground on the svideo jack The other problem was i made the "PAL/NTSC" switch mod where i connected ground to the PAL setting, but not the NTSC setting but i saw that before i assembled it. Well well enough about me rambling. Biggest failure i had so far is forgetting to connect stuff. Another problem i had was when i tried to figuer out the composite problem. When i connected the inlline cap the cable stopped working! So i added the 75ohm resistor! When i added that it worked again. Also if i removed the cap and left the resistor it still worked. Is your current wiring the same as before? http://rguichelaar.dyndns.org/games/cables/n64_svideo_1024.jpgHave you ever successfully preform the S-video mod on any other N64? Did the system worked with S-video before you preformed the mod?Also have you ever considering wiring the way i did or make a AV-Box. Reason i ask is because you can always "test" the system with the Multi out if you hit any problems. That´s how i figured out my problem.So far i have checked the picture that you uploaded. Is it possible for you to make a video about it? The only things i can see from the picture is that maybe the solder joints might be "ok" but need some touch up "maybe"?Btw washed out colours you said. Is that the same as "Overbrightnes picture"? If so maybe one / more components doesnt make a good connection.Please check these spots with a multimeter: Sorry for long reply.
