'Hi to all,
Iam new here. Ibought a cpc464 and it seems that the screen every 2, 3 sec shacks with the scart cable. And if I put a Video adapter it doesnt shakes anymore but of course the colors are B/W.
Anyone knows why?
Hi and welcome here. Did you try another monitor?
i dont have a monitor, only TV ;(
I think i found the problem: My LCD TV its too modern. Can it be?
Hi and welcome,
unfortunately your TV isn't able to lock on to the exact sync frequency the CPC is producing. Video adapter is a very broad term, which type do you mean? If your TV has S-Video, it might be worth trying to connect via that?

On S-Video works, but only B/W.
If it's B&W then it's not S-Video, your TV is only detecting or displaying the Composite part of the signal. Without hardware like this: Limited batch of new S-Video Adapters. (http://www.cpcwiki.eu/forum/amstrad-cpc-hardware/limited-batch-of-new-s-video-adapters/msg60857/#msg60857) you can't get an S-Video signal from a CPC.

Sorry Bryce, you right: it is not S-Vide, its composite.
Now I try , connect the scart on my VCR input, ad it stil B/W. Only if I connect the scart directly to the TV i get color, but it shakes.
I have a E-motion plasma TV.
Probably your VCR need to set the input signal type from the scart cable.
What if i buy a Scart -> Vga cable to connect the 464 to VGA input of my TV or Monitor?
Has anyone try it?

Absolutely, that can happen. Maybe you can check with a monitor or tv at a friends place, then you know that CPC and cable are ok.

Yep, all this emotions can shake a pic quite well! :)

I see it must be the bloody TV
Thanks a lot to all
Try to get an old Sony Trinitron. Reliable and superb picture.
Does the TV have a seperate S-Video input (4 pin round connector) ?

No, it has not S-Video input.
But is has Component Video, 3 inputs: Y, Pb, Pr
Then there's a good chance that the S-Video pins in the SCART socket aren't connected. The TV definitely isn't suited for retro use.

Which S-Video pins in the Scart should be connected?
I read that some scarts needs a 1,5V battery in the 16pin of the scart

... 3 inputs: Y, Pb, Pr
Y = Yttrium
Pb = Lead (Plumbum)
Pr = Praseodynium
... nice mix of elements :)
Here, how the MP2 look to handle the signal from the CPC to the Scart out.
My friend iXien let me see inside, because it allow to get a sync picture on his LCD screen. (not the schematic usually found on internet)
[attach=2]
That's just adding a voltage to pins 16 (RGB select) to keep the TV in RGB mode and pin 8 (Aspect ratio) to force the TV to 4:3 format. are you sure about the value of R23? I would have thought it would need to be a bit larger.
Bryce.
Sure, but not only.
Some schematic on Internet said to use the luminance signal too. Look to be wrong.
I understand, but yes... Both are orange, orange, brown, gold resistors.
I don't think I've ever seen an official schematic for the French MP-2.
Bryce.
I was surprised to see so few things inside.
There are the PSU part close to the PCB with this dirty hack (many straps) instead of the expected parts drawn on it.
i try my cpc with a CRT TV and it works fine ;D
Bloody Plasmas!
