B&O MX4000 shaking image

[Eminent]

Hello Pro's.
I just bought an Bang and Olufsen MX4000. I choose this telly for it's short neck on the tube.
This for a better fit in my cabinet which i'm building, but also for the adjustments which i can make when in the service menu.
Connected to the telly's scart is a jamma 60 in 1.
On other TV's  it worked nice, just a bit off-set image.
On the B&O the image is shaking a lot.
When i connect a decoder to the B&O's scart there is no problem at all.
In a schematic to use scart for our hobby i saw that there are resistors and capacitors used also.
I didn't do that, could that be the cause of the shaking image?
Any thoughts?
Thanks for your answer.
Rini.

Just bumping this as I have a beovision 1 with what sounds like the same problem although I'm sure it wasn't like it when I first got it (or I certainly didn't notice it anyway)

Is the whole screen shaking or is it more at the left and right edges?

[Eminent]

It's the whole screen.  I ordered some resistors and capacitors to put in the sync and RGB line. See if that helps.
Keep you informed.
Thanks.

Well. I just put a 500 Ohm pot in the sync line, and this solved the problem.

Hi, I've decided to do a build my self and I have a sweet deal for an MX4000 on hand.

I do have a few things that are worrying me.
How do you get the TV to automatically power on and select the Scart or S-VHS ?
I would really like a one button solution that power up both the TV and PC at the same time - having to use the remote as an extra would be a bit of a downer.

Thanks in advance / nanoflower

The TV starts automatically on at scart. There is a 12V and 5V at the scart, i don't know which one is for the TV to go on.
But the problem i had was that it won't go on when power on the telly and the jamma board simoustainly.
So i used a delay from Moeller like in the attachement. On this way the jamma board powers up 10 seconds later and the telly goes on.

thanks, useful stuff

Hi again.

Do you use the CRT_Emudriver for this set?
If yes, then how did you define it in vmmaker.ini and Mame.ini ?

[Eminent]

Hey. I don't have a PC with Mame or such in my cabinet. I use the Jamma 60in1 board. Think you have to ask somebody else. Succes.

Any change you uploaded some pictures of you Arcade somewhere?, I'm a bit curious about how it looks

[Eminent]

I will. Didn't take much pics, but i will share them here.
