hi guys... recently i found a n64 for a bargain here
even i already have on totally functional, for the price, i give a shot

after i cleaned and stuff, turned on and image goes up, but with this strange colours scheme
anyone knows what can be or what can be done

i've already test with another cable, tv.... everything

NTSC game, NTSC console, NTSC tv


thx in advance =)

 

i thought that too
but with my another n64, even my gamecube (the same cable) the colors are normal
=/

 

yeah, i tested a bunch of games, in fact i've got a ed64... so i tested A LOT of games indeed
my other n64 is a brazilian one, solded by gradiente, and work normally
is there some tweak that i could do?

 

For whatever reason, it seems like the red color is missing entirely, I'd guess it's a hardware problem with the N64 itself, maybe the chip on the board that outputs RGB color has a burnt out pin, or there's some problem between that pin and the components that convert it to composite video. I don't know the N64 internals very well, but it's almost certainly an internal hardware problem, as the conversion from RGB to composite happens internally.
Edit: Wait no, if red was faulty, it wouldn't be able to display yellow, so it's able to display red to some degree when combined with other colors but not pure red. Very strange.

 

Unfortuantely, I think there's no easy tweak... I searched for a solution back when I had this issue only to find tutorials to re-mod the console to fix the issue. Stuff about changing the NTSC crystal... I'm far from an expert in this area... =/ If you're still willing to fix it, try googling for "n64 pal m ntsc" (no quotes). There was a lot of similar problems posted in brazilian forums. Yup, PAL-M is a b*tch... Only Gradiente made it work almost perfectly (high-res games show correct colors but have an uncentered screen).
Also, to be sure if this is the problem indeed, you should look which color system the TV is showing with the N64 on.

 

UPDATE

i just found that was modded by the previous owner, awful made tho

ntsc to pal-m

just change the oscillator crystal and everthing backs to normal!!!!
