Hi,

Last week I purchased a mx7000 with sw 4.3. After a lot of fiddeling I got the picture settings how I want them.

I've been playing n64, gamecube and laserdisc on it. Works great!
The only problem I have is that I can't change mono to stereo for any device. It's stays on mono. I have the beo4 remote and when I select sound en press go serveral times, but it just tells me its mono. They are all connect through scart.

Both speakers sides are working, but how do I set them up to work in stereo?

Longtime lurker here,
I bought a Mx4002 with sw 2.0 just over a year ago for my game room and this thread has proved invaluable.
To access the service menu I installed a spare arcade push button on top of the set.

Also I found that the deinterlacing mode works on my model by simply highlighting shift on the remote and pressing 7.

Thanks for the info everybody.

I have obtained a MX8000 and I have done a quick G2 adjustment, it seemingly were set too low judging from B&O G2 calibration screen. Just a tiny adjustment and the standby light went from yellow to green =) All good!

I've read that many prefer to disable the SVM (B&O VisionClear sharpness stuff), since it might bring a bit "too much" sharpness to the image, especially for 2D games. I tend to agree judging from a quick and dirty comparison with my MX7000. Disabling it on the MX8000 did make for a softer image more like the MX7000...HOWEVER! I also noticed that my MX7000 is significantly sharper vs the MX8000 (SVM deactivated) . And I don't think any calibration can make it on-par with the MX7000 sharpness, well as long as the SVM cable is detached that is.



Anyone experienced the same thing comparing the two sets?

I have a small question. Can I get s-video out of a scart port with a s-video adaptor? Or do I need to use the s-vhs port?

I have two devices who both use s-video for the video signal. Would be nice if I didn't have to change the cables all the time.

only if the device in question has a switch. S-video through scart uses the composite video pin for luma and the red pin (from RGB) for chroma. This means that a scart port can't output composite video and s-video at the same time.

I didn't mean it like that. Can the scart port on the mx7000 receive s-video from a s-video cable with a s-video to scart adapter?

Most likely one of the two SCART ports can accept S-video viable those standard SCART adapters. This is the case with my Beovision 1 and MX 4000.

I would say the opposite is true on mine, the MX8000 set has a sharper image than my MX7000 even with the SVM cable detached. Did you hppen to watch my youtube video about it by any chance?

Retro Flex? I sure did ;)

I am honestly shocked how great the image is on my old MX 7000, if I remember correctly it was manufactured way back on 93/94. It might have seen little use, or the MX 8000 did see an excessive amount of use lol. I don't know. I have managed to get my hands on a second MX 7000 unit last week, sofware 4.5 and it was manufactured in 2000. However... the anode cap cable seems to have seen better days. I will need to try and fix that before I take my chances on getting it up to speed picture wise!

Suddenly I have way more CRT's.....3 B&O's, three working Sony Trinitrons (managed to bring my parents 99-model 29X5e back to life) and a small Philips I will need to inspect further. I will need to re-arrange my retro space and try and set up a few TV's and narrow them down to which console fits what lol.

Out of curiosity, what are your settings under the picture menu when in the service menu?

Hi all,
I'm a complete novice with CRTs and have just got a MX4000, but can't seem to get a clear picture. Lines/edges seem to have a wavey/flickering.
Just wondering if anyone here would know whats up, some footage:
https://youtu.be/wTT--M2EzNU
Even the built in TV menu seems to have the same effect if you look closely. Have tried NTSC and PAL resolutions via a raspberry pi plugged into the scart port, but same problem on both.
Many thanks.

Just picked up an MX7000 and it has terrible geometry, like looking at it under rippling water (both horizontal and vertical scrolling tests show distortion like a fisheye lens).

Can anyone point me in the right direction to a solution? Not afraid to change the capacitors if that's the answer, but will need to research some specific guidance as I haven't done it before.

Thanks in advance.

Golden mate! Seems like we had near identical settings dialed in! I have been going trough all my CRT's lately and sorting them out, yesterday I hooked up my oldest MX7000 vs the MX8000 again after finetuning both of them. NOW I got the results I expected, overall sharpness on the MX8000 is indeed better than the 7000, WITH the SVM cable detached! I'm still more fan of the speakers on the 7000 though to be honest. I'm also am happy to report that the latest MX7000 pickup I did a few weeks back seems to be doing OK! I fixed the arching fram the flyback transformer, and it seems to be in a good shape now! Need to clean the contrast screen, since there's a lot of soot and grime on the inside. It's hard to tune in the sharpness and contrast with a literally BLUR-filter attached :lol: Geometry holds up well vs my other B&O's.
