Title: Look what the mailman brought me today! :-)
Post by: mr_lou on 15:53, 14 July 15
Finally it's my turn to get a GX4000.  :)

Seems to work fine, when using the same scart cable I'm using for my CPC+, but the picture seems very "dusty" compared to the bright picture I'm getting from my CPC+.

Does anyone have any ideas about that?

It seems to be in really neat condition! BTW, the picture of the pads shooting fire is simply amazing, there were different times, that is for sure  ;D :D .

I don't think I've seen any other games console that has been looked after as well as the gx4000

Wonder why   :D

@Bryce (http://www.cpcwiki.eu/forum/index.php?action=profile;u=225), do you have an idea about the dusty picture?

I have my CPC+ connected to a Phillips 14" CRT TV.
I use the same TV and the same cable to connect this GX4000, and while my CPC+ gives me a great bright picture, the GX4000 gives me a dusty picture, like brightness has been turned up a lot and contrast has been turned down a lot.

This isn't normal, is it? You think it's a component that has gotten tired?

Does the SCART cable have resistors in it?

Is that one of those 'New old stock' GX4000's that the UK seller has been selling heaps of ??

Been thinking of grabbing one of those...

Cheers,
Shane

Um... I dunno. It's the same cable that was with the CPC+ that you modded for me. So I guess you'd know?
Shouldn't the same cable that gives a great picture on the CPC+ also give the same great picture on a GX4000? I mean, aren't those two machines roughly the same in that aspect?

Yup, that's the one.  :)
Very nice condition indeed, but this picture issue is annoying. I hope it's easy to fix somehow.

Question:

The box shows square cut outs around the connectors, I don't think mine has those, I think the cutouts go around the sockets neatly.

Like this:

and see here:

strange the box shows big cut outs at the front.

Yes, but I didn't make the cable did I?

The Plus and GX4000 video circuitry are almost identical. The only difference is that the RGB signals are also sent to the RF and SCART circuitry in the GX which could lower their peak values slightly. Have you tried connecting via the SCART output?

Try using a normal scart  to scart  cable. Mine is perfect that way. The monitor output is meant to be used with a cm14 and the 5v supply not the 9v one.

If using 5v use the din socket.
If using 9v use the scart socket.

Using the 9V with DIN isn't a problem, but using the SCART socket with 5V means you loose the switching signal on the SCART socket.

Ahhh. I guess that makes sence. I only tested 5v with my cm14.

I honestly don't know. You might have, but I don't think so.

Did just now. Gives an amazing picture. Even better than my CPC+ I think!
I guess that means the dustier picture from the monitor out is normal on the GX4000....

Thanks!

Mystery solved.

Use the 9-volt PSU = SCART plug gives a perfect image.
Use the 5-volt PSU = DIN plug gives a perfect image.

Yes you did. I admit I missed that for some reason. Saw it after I posted though.
