How to Disable VisionClear SVM Digital Sharpness Processing on a Bang & Olufsen MX8000 CRT
A Mod / Hack to disable the VisionClear Scan Velocity Modulation (SVM) digital sharpness processing circuit on a Bang & Olufsen MX8000 CRT.
Warning! Please know what you are doing or use someone qualified before working on a CRT as they can carry extremely high voltages. Perform this mod at your own risk.

Bang & Olufsen MX7000 CRT - Retro Gaming TV
Просмотров 4,9 тыс.5 лет назад
Little demo of what this set looks & sounds like for Retro Gaming. Playing games from a modified PAL SNES in NTSC format using MSU1 Enhanced Audio. This model is fitted with an active speaker system which sounds great and the screen generates some really nice scan lines.

    Is this VisionClear on all of the MX8000's? I only ask as mine doesn't give anywhere near as sharp of an image as your comparison shots show (when still connected). I doubt the previous owner disconnected it as he was an old chap (not used it for retro gaming 🤣) and he'd owned the set from new (2003).

    That added SVM sharpness doesn't really bother me that much and it doesn't create "ringing" artifacts etc what I can see, so it's ok from the distance I'm sitting. What I would like to do though is turn off the sensor that makes the tv set adjust brightness and contrast according to available light source. I wanna be able to turn it off and adjust it to my own liking but doesn't seem to work to disable that sensor without loosing remote control function?

      Unfortunatley not no. I dont recall the MX7000 having an ambient light sensor though but I could be wrong.

      yeah the MX4000 and MX7000 are known for being a bit dim due to the contrast screen in front of them (which can be removed btw), plus they are old sets now its likely that some of the components might be wearing e.g. capacitor. They should still have a nice picture if its working correctly!

    If you open up your SCART cable and disconnect pin 8, the widescreen problem goes away. I have an MX4200 that has the same behaviour. For some reason, every SCART cable seems to wire up pin 8 with the voltage that sets 16:9.

      Hi! As always you will need someone who knows a bit about troubleshooting electronics etc, and I know that is increasingly hard to find these days but I suspect from what you describe it would be capacitor related as is quite commonly the case with aging electronics.

      Better RGB mode colours as they were a bit washed out and couldn’t be adjusted on the 7000 and the 8000 also has a much better menu system and a few others things I’ve already mentioned in this video and the pinned comment. However the 7000 is still a great tv it looks identical to this one and has the same amazing active sound system, they are a lot more common (in the UK anyway) as took me a long time to hunt down an 8000.
