Reply To: On Sony CRTs and D-sub-SCART cables

Yeah, you can read some people having color issues with this Sony chassis (FE2) yet never it’s properly diagnosed. I’m still to find it fully documented, at least. So I’m not really sure which are the intolerances exactly.

I’ve tested it with two different units though, both behaving the same:

· Japanese Sega Saturn with C-sync TTL cable: severely wrong colors, kind of greenish

· Japanese Sega Saturn with sync on CVBS RGB cable: accurate colors

· PAL PS2 slim with sync-on-luma cable from RGC: only red is darkened

· PAL PS2 slim with unexpensive RGB cable (I assume sync on CVBS): accurate colors

· Japanese DC with two different RGB cables (they were unexpensive so I assumed as well they were sync on CVBS): red is darkened, unsure if the rest are really fine

· RGBHV D-sub to RGBS SCART with a resistor to join syncs: only red is darkened

All these cables were already tested on different TV sets with no major issues detected.

Likely the major color issues I get with the SS C-sync cable are due to it not having attenuated electrical signals for consumer TVs, but inferring that this TV chassis only tolerates sync on CVBS is the only answer I can think of. I’m far from being an expert anyway, so maybe I’m missing something.

Do you know of a device which safely turns either RGBHV or RGBS into sync-on-CVBS RGB?

Also, could you confirm that sync-on-CVBS RGB uses pin 20 also for R-G-B and leaves pins 15, 11 and 7 withou any use?

(I’m a bit surprised that sync-on-CVBS RGB is so widely ignored by European cable makers, despite knowing that digital devices usually don’t support it.)

Thank you.
