Faint jailbars on AV Famicom with NESRGB

Post by Koolhass » Sat Jul 04, 2020 10:53 am

Finally i got up and running my AV Famicom with a NESRGB install (somehow i killed the CPU, so i ordered a replace and everything is fine now)...... but !!!, i have a little nuisance. When i see games with a light color in the background, as the sky in Super Mario Bros 3, i detect some very faint lines, something like jailbars, but very subtle. I took a picture but is hard to notice without horizontal movement:

So i know it could be a lot of factors.

The console is original, i only replaced one capacitor, the one next to the reset button.
I use the OSSC with this RGB cable: https://www.retrogamingcables.co.uk/SUP ... CART-CABLE
I didn't cut any traces on the board.
I did remove the composite capacitor
I don't care to have composite video.

In the RGB install, i used the original AV output of the AV Famicom, and the CS, R, G and B of te NESRGB

Any ideas of what can i do to improve image??
