I have one Sony BVM 2010-C that I have acquired a couple of months ago, but I have some problems with the image.
I tried to use a PS2 and a Nintendo 64 with yellow composite cable, and here is what I obtain :
- While using Video Input A : https://www.youtube.com/watch?v=g_5VZ4cJgWs
- While using Test input : https://www.youtube.com/watch?v=llo5jKliLaw
I'm using a Composite-BNC adapter and a 75 ohms resistor like this :

(That's not a picture from me, it's a RGB configuration on this picture and i'm using Input Video A or test (Green) input because I don't have any RGB devices, only composite or SCART).
Also, I don't have any user manual or operation manual for this television.
Feel free to ask me some questions if you need some others information.
Regards,
