Genesis with dim RGB picture?

Jibbajaba · Dec 11, 2014

I don't know if this is just a known issue, but my model 1 Genesis outputs a pretty dim RGB picture, requiring me to crank up the brightness and contrast on my monitor when I play it. I cracked open the SCART hood on my cable, and the resistors and capacitors are there, and are the correct values. Is there anything I can do without modding my system? Is this a known issue with early Genesis systems? Mine is a "High Definition Graphics" model with no "Produced or Licensed by" splash screen.

Thanks!

non-TMSS with dim RGB video.

hmmm

I made my own scart cable and it looks fine on my PVM-2530.

interesting..

Maybe try removing the resistors just to see :/

Could also be your power supply

I think I have another Gen 1 MD scart cable you can pick up when you're over on Sunday. That may help you to narrow things down a bit.

Thanks, Teddy.

I should say that when I say "dim", it's just that the colors don't pop like they do on my Neo unless I crank up the contrast. In chat, Ballz suggested that I try removing the 75 ohm resistors, since I already have 75 ohm terminators on the back of the monitor.

I find this odd, my model 1 has blindingly bright output without the resistors. Even with them it's still on the bright end of my systems.

Maybe the inline caps in the scart cable are dried up. Try replacing those.

Good idea, I know some systems look dark w/o the caps. Replacing them is worth a shot over removing resistors.

Sounds like a good idea. I'll check my stock of rando electronic supplies and see if I have some. If not, I'll get some.

I've noticed that a lot of SCART cables use cheapo quality caps so that could very well be the issue here.

I found some caps in my stash, so I will try changing them out tonight. Although they look like the exact same ones that are already in the cable...
