i installed the mod but the image isnt syncing proper not sure whats the issue i tried two different cables removed the cap on it nothing.

I had the same kind of issue with my SNES Jr/SFC Jr despite correct soldering points on console board and the same Retro Gaming Cable NTSC SCART cable as yours with the Nintendo RGB Bypass Amp Revision 4.1b by VGP.
I remember I had to solder jumpers J2 (Change Csync Attenuation) and J3 (Buffered Csync) to sync picture properly. Since done, it works like a charm with a perfect sync and crisp RGB signal on my CRT (via SCART) as well as an upscaler (successfully tested on OSSC and RetroTink 5X).
I hope it’ll help you.
I finally tried soldering j2 and 3 and it just stayed the same ill try to just de and re solder everything i guess not sure maybe a wires crossed
redid everything tried all combonations i got it to move around slower and more clear now but still wont sync no idea lol

I dont think you are picking up the CSYNC signal from the right place
