Sega Genesis Color Issue

[dangil]

Hi there

My name is Daniel , and I am from Brazil. I joined this forum to see if I can find some answers on how to fix my Genesis

here is what happens:

I have a USA Genesis 2 (I don't know if it was transcoded to PAL-M or not) connected via Composite to my TV. If I let the TV on auto, it displays a B&W image with noise. If I change to NTSC or PAL (PAL-N), the image remains the same, B&W with noise. If I change to PAL-M the noise is gone, there is color, but the hue is off.. like blues look purple, and so on...

the interesting fact is that if I connect a 32x to this Genesis2, the image output via the 32x is perfect.

does the 32x gets a RGB input from the genesis and reencodes the video to composite?

is the genesis video encoder or crystal damaged?

I also have a Brazilian Genesis 1 that has this same behavior, but I can't connect the 32x to it since I don't have the din->mini-din adapter.

what would be the first step to check this issue and try to solve it ?

thanks in advance!

sounds like the crystal..

sub carrier seems off..

[dangil]

but is it a common thing to happen ? does the crystal wear off with time ?

I just think it's too much coincidence to have 2 genesis with the same issue... a third one that I have is fine, so it's not the TV (I tested the other ones with 3 TVs already)

I will try to change the crystal so see what happens

thanks !

Well, i've honestly never heard of such a thing happening.

You should match your region console to your region TV. That's the BEST way.

OR if your TV has RGB SCART inputs, just get an RGB SCART cable and enjoy the wonderful world of RGB. (the highest picture quality your genny can do)

I'am assuming that you have a north America console,I don't think there is a problem with your Genesis.Most likely is a region issue.Have you tested this system in a NTSC tv set?..which they are probably hard to find in your region.Also,you must know that there is NTSC 3.58 and NTSC 4.43 a nice video converter system may help you....I had a problem like that with one of those cool Brazilian TecToy Sega Master System II(the one's with the built in games)because I live within USA and my COM World digital converter tooked care of it!...Problem is,they are a bit expensive..
