I'm watching my MX6000 now exclusively using RGB signals since the internal tuner is useless over here nowadays. I have a slight problem with the picture sharpness, though. This is most evident when I call up the menu and the picture underneath switches to composite. I know that is mostly artificial sharpness and I can't stand watching composite otherwise, but still the RGB picture from the stb is somewhat soft compared to my old Finlux.

The onscreen menus and teletext are razor sharp (and I've cleaned under the contrast screen...) so I don't think there's much to improve with adjustments. I noticed though that the RGB signals from the AV connectors go through rather complicated level clamping and switching networks - are there any components that could be upgraded / modified to improve the frequency response?

Have the same “problem” with my MX7000. The picture is a little dark and soft, but when I press menu, the picture moves slightly to the right, and switches to (the much brighter) composite.

The same thing happens when I press AV-CD… Annoying…

Better SCART leads?

Bypass the SCART switching ... ouch ;o)

Better SCART leads?

The problem is definitely the MX. I can compare the picture with the same STB and SCART lead anytime with my old tv.

I don't have the schematics here now, but from the quick look I took, it seems the RGB signals are switched passively between AV1 and AV2 using biased diodes - hardly videophile quality... It wouldn't be too hard to bypass this and hardwire RGB to only one of the SCARTs, with obvious drawbacks but sharper image. Well, I'm sure it's all surface mount components and I'm not going to touch that. Maybe I'll revert to Y/C, it seems to be implemented better...
