Hi! I bought RGB modded Japanese N64 console few years ago. It has done with the simple 3 wire solder method (this method http://www.mmmonkey.co.uk/ntsc-nintendo-64-rgb-old-guide/). Everything was fine when I got CRT but now I have LCD and XRGB Framemeister so the picture was a little bit too dark. I bought RetroRGB Amp so I can amplify brighter picture. I installed it with using this tutorial (http://retrorgb.com/n64rgbmod.html). But I get white screen when using RGB scart. I did not soldered the sync wire. I think that is optional. It should work without it. I am using the same RGB-cable that I used with the simpler RGB mod. (It looks like this cable, It has RGB and component in it http://ecx.images-amazon.com/images/I/71RoXY4uEqL._SX385_.jpg) When I use component I get black picture (cannot see a thing). TV and Framemeister gives same results. But when I use that cable on my RGB-modded SNES mini component gives component picture. I tried with another cable. (I have RGB modded SNES mini (NTSC-U)) And I get the same results. The cable has no component, only RGB. I recheck the RGB-mod for cold joints and reheated them, but I get no results. I removed the RGB mod PCB, to be sure that the N64 is not faulty and soldered 3 wires back for the simple mod (with little too dark picture) And it works on that way. Do you know what is the problem. I would like to get brighter picture, but i don't know what to do. Somewhere is the problem. a) The console itself b) RGB-mod is faulty I don't believe the cable is faulty because it works with RGB-modded SNES mini and it have worked with simpler mod. EDIT: The RGB-cable with component cable gives black picture with the simpler 3 wire mod too. Thanks!
What revision motherboard is it? Do you know for sure if the cable is sync on luma or c-sync? Does the amp PCB you got from RetroRGB have just three pads (for RGB only) in the corner or does it have four (RGB+Sync)?
I am not sure about the cable. It is 3rd party, but it has worked well with 3 wire mod. (There is no R, G and B wires on the picture. I took the photo before I soldered them). 1. Why is the composite picture dark? Is there problem on the console. Or is it dark because RGB mod is done? It gives dark picture with the cable using both RGB mod method (RetroRBG and the simple mod). I have not tested if it gives dark picture if I remove all 3 wires. (Console is now with 3 wire mod) 2. Would this Scart helpfor this situation, or am I just wasting my money? https://www.retrogamingcables.co.uk...a-csync-rgb-av-scart-cable-lead-cord-for-sale These pictures are of my mod and the RGB scart I have now. EDIT: I think the motherboard was NUS-CPU-02
The mod board looks fine (as long as you connected the RGB lines after you took the picture). The mod board does not amplify/buffer a c-sync, but you don't need it to as N64's with motherboards NUS-03 or below have a buffered c-sync built in. I think you have a cable problem here, but I'm going to let someone else (potentially more knowledgeable) try to advise you before I say much more. The cable you linked to is a sync over luma cable. I think most people use that cable or something wired exactly the same. However, I personally use a c-sync cable because my NUS-03 console supports it. I don't have any point of comparison or evidence, but I thought my Framemeister would be more stable this way.
not sure the board work fine with the n64. Was made for the SNES Mini/jr. But like the tutorial it will work. You connect the c-sync option? When yes, you need a csync cable. You better buy a "ntsc" csync cable finished for this mod. I also think the problem is your cable.
On NUS-03 and below, c-sync just is connected. It's only on NUS-04 that you need to manually buffer/wire that back up.
it looks like there is a cap and maybe a resistor and on the composite video line that should not be there. there should also be caps on the r, g, and b lines. maybe that's a pal cable you have http://members.optusnet.com.au/eviltim/gamescart/gamescart.htm#snes
Considering the rgb is a mod, you can't base the cable on ntsc vs pal consoles that use different output circuits. Cable needs to match the mod, not that it's an ntsc or pal console.
this particular mod needs an NTSC cable. the composite video line though has nothing to do with the rgb mod. possibly its connected to c-sync though.
So...the best cable to recommend for a NUS-03 or below RGB modded N64 is a NTSC c-sync Super Nintendo cable...correct?
I checked the motherboard and it says NUS-CPU-02 (it is japanese). I tried the console with official Nintendo Gamecube Pal cable too (I use that cable with my RGB modded SNES Mini console) but that gives me the same results. I have understood it would be compatible cable for that RGB-mod too.
You know, looking at the rgb amp picture, it looks to me like the rgb pins aren't soldered too well. Reflow the solder on the pins and try again with gamecube pal rgb cable (I use that cable on mine).
I have double checked all the pins and flowed solder to the pins. It did not work so I removed it, then checked with "3 wire mod" that console works, put it back and all I can get is white screen on RGB. I was not sure was the cable that I use in "SNES mini NTSC-u" Gamecube or SNES RGB scart. So I opened scart to see, there is 4 capacitors and 1 resistor to see on the mother board. And the motherboard is marked "YG-H2". It looks just like the scart in: http://www.mmmonkey.co.uk/official-pal-gamecube-rgb-cable-on-ntsc-consoles/
Ah, sorry. I missed that you posted that already. Could you post new pictures of the install, showing all points you've soldered too please? Are you using the correct scart adapter for the framemeister?
yeah, either an NTSC Super Nintendo/Famicom or PAL Gamecube cable should work as they are pretty much the same. There is probably something wrong with the amp then.
I removed the amp, I contacted the seller and he says he would send me another one on the next week. I think there is something wrong with the amp. I am using Euroscart adapter on the Framemeister, I ordered it from retrogamingcables. Everything else works perfectly. Nes, Snes mini, Saturn, Pc engine Duo-R and Sega CD-X. I have soldered many mods before (first ones was on XBOX), but this is the first I have some troubles with.. I will post when I can get another amp. By the way: NTSC Super Nintendo/Famicom or PAL Gamecube cable use csync or luma?
The official ones use composite video but there are aftermarket ones that have any of the 3 (at least on the NTSC ones).
