I finally got a bvm 20f1e but I have some problem with geometry, I'm using a snes JR rgb modded with an rgb amp and 240p test suite and I'm experiencing some weird distortion expecially on the right side of the screen:
I've read all the chapter about the alignment menu and tried every option but it seems that I can't solve this issue.
is it a configuration problem or some hardware problem like the capacitors on the deflection board?
Edit
Little update, I've detached the deflection board to examine the capacitors and none of them seems leaking or "fat".
I've launched the 240p test suite from other consoles (nes and mega drive), the imperfection is still there but way more less noticeable.. I'm really confused..
All the consoles ouput rgb with a shielded scart cable. On the same chain (located just before the 20f1e) I've got also a pvm 20l2md and the issue is not present in any console I've tried
thank you in advance for your help
