SNES mini RGB image issue FIXED :D

hi, i RGB modded my SNES mini useing the instructions from RetroRGB. But when i use it with my framemeister i get these lines that are stationary and start from the bottom left to top right and a extrealy faint line going from bottom right to top left, which i didnt notice untill to took the photo. (it looks alot worse in the photo than it appears)



I never noticed it when i used a pvm 14" crt but now when i look for it i can see the line going from bottom left to top right



any ideas on how to fix this? Dose it look like interfearance due to a cheap scart cable?



EDIT: Still digging for answers, might be a better cable in order. Came across a pic the better demos my issue http://i.imgur.com/N2fdP2x.png



MORE EDIT: welp.. thanks to ccovell of chrismcovell.com  my issue got a fix. just had to bridge a pad. check out those pics and the original post at http://shmups.system11.org/viewtopic.php?f=6&t=47617&start=2010



EVEN MORE EDIT: pics arnt working for me, youll just have to take my word on it

    i know some models of the snes used different chips to render the graphics some had more noise than others ive seen the lines in certain models of the older snes using s video connections. from your picture it appears normal to me. im not completely sure though.

    Did you build a amp or simple wires and resistors for RGB build?  What is your sync method? This looks a lot like the issue that N64 RGBs display when using composite video as sync this is known as "crosshatching"



    Also Sony PVMs seldom display crosshatching issues.  They have a superior way of using sync information. Composite sync equals Csync on most models. XRGB mini models are more temperamental. Also what cable are you using? Where purchased?

    I can see the diagonal lines on my sony bvm-20f1u and my sony pvm 14”



    as for the scart cable, i cant remember and im thinking /hopeing that is the issue. i dont recall spending much on it.



    i have seen posts where people have said they had the issue with shoddy s-video cables,



    Im in the process of getting some quality cables from retro_console_accessories, but if all else fails I did come across one person who solved their issue by bridging the C48 capacitor pad on a SFC jr

    Yes retro_console_accessories.  Simply the best for premade USA cables.

    Thats what I use and test with.



    I have seen many crap scart cables.  Plus there are Pal versions and JP21 versions that can mess things up. Many sellers have no idea what the cable truly is.

    yeah, i ended up putting in a order to replace all my cheap ass cables. Its gonna cost a bunch but im over audio hum and diagonal lines. Getting them all coax and RCA breakout, all my audio will end up bypassing everything going straight from the console to a AV switch. Just clean video signal going through the scart hub to the xrgb mini.
