SNES Mini RGB Mod, No Video. HELP!!

Have tried to do the RGB mod on a SNES MINI, but im getting audio but no video. Here is the install....



I first tried without the orange composite sync wire and then with but still didnt help. Im using this SNES Mini in conjunction with a XRGB-Mini. I take it the SNES Mini uses the same RGB scart lead as a standard SNES console?

 

Yes, but the lead uses composite video not composite sync (unless you bought a 3rd party cable).

Does the xrgb need csync?

Also, test the fuse in the console, as it's very easy to blow them when working on a snes

 

Yeah i got my snes 3rd party cable, i think i got it from retrocables.com or the ebay seller retro_console_accessories.

How can i find out which type of sync the cable uses?. Here a pic of the scart lead btw...



and the type of resistor i use on the R,G and B lines....



Purple, Green, Black, Gold and Brown which i believe is 75k??

 

first thing id do is plug in a composite lead and see if that works, if not check the fuse

 

also, you are using csync in not csync out on the s-rgb chip. pin 18 is csync out

 

Yeah i check with a composite lead before i started the mod just to make sure the SNES work and it was fine. Ah so i have the wrong pin soldered then, and need pin 18?. I was following the guide here...

Hmm ok i remove the sync wire from pin 7 and placed it at pin 18 as suggested, but still no display.

I should add that the input light on the XRGB-Mini does come on when i turn the SNES so it is receive a signal for the SNES, im just getting a black screen with only audio, and im still getting video via a composite cable so the SNES hasnt been damage from the install in anyway!.

Im wondering if its the resistors im using, what would happen if i didnt use any resistors at all??

 

check with composie now, because it worked before the mod doesnt mean you have not blown the fuse since

 

Yeah composite still works fine.

Im sure i do, but i am using the right resistors right?

 

I have the wrong resistors....



Purple, Green, Black, Red and Brown

7,5,0, x100, +1%

So im actually using 750ohm resistors, would explain the black screen i guess. Will teach me to only read the label on the bag and not actually check the contents

 

YEAH all sorted now!!!!! SNES MINI now RGB modded, i used 68ohm resistors!. Pictures captured with SNES MINI going through the XRGB-Mini....











Any suggestion how to best deal with that 'Blistering' on the top of the case, i know im not going to be able make it look like new, but if i could reduce the appearance of it would be great. I was think about getting some super fine wet and dry sand paper and giving it a go??

 

I'm confused. This picture is a 75 ohm resistor (not 75k ohm). Purple, Green, Black (750) x Gold (0.1) = 75

Is that an actual picture of a resistor you used? Because with ones like that, your picture should have been fine, unless something else was wrong. Or, were these the only ones you used:

Actually, these would be 75k ohm resistors (not 750 ohm): 750 x 100 = 75 000

Having 1000x resistance would certainly cause a black picture.
