@jdryyz
the cable must be modified to provide expected voltages for new TVs. (pin 16 is most important)


The scart converters ignore the scart signaling pins so there's no point. He's in the USA and doesn't have scart on his tv.

If it's true, then it's simple:

jdryyz wrote his cable was working with his hdmi converter.
the scart converter is supposed to ignore all but rgbs.
no picture = scart converter malfunctioning

But, isolating a/v mode on scart cable makes my tv staying black. cutting everything but rgbs then tv ignores the cable and displays standard tv channels.
i do not know how his converter is working. measuring the cable would allow to identify the problem if all signals are on, because then it is definitly the box, that refuses to work. that was the idea behind.

Thank you all for your input. I would like to believe I simply have a defective converter box. Then I can just return it. I would really want to be sure the box is faulty, though. Is there some way we can test the box itself to PROVE it is the fault (besides not getting a picture)?

I can attach a photo of the circuit board. Let me know.

Any working video source will do.
Like:

sat-receiver
vhs-recorder
dvd/br-player
game console
home computer

As long as these devices are built to support tv output and there is a working cable.

If you're no hermit you might find one in your neighborhood :lol:
or look for retro gaming groups, meetings.

Keep in mind, my Amiga 500 via RGB -> SCART cable is the *only* source I can pass through the converter.

I'm in the USA so I do not have any native SCART-capable displays to use either.

You asked for a method to test your box (converter).

It is not about devices with scart interfaces, but video sources that have rgb out and can be directly connected to tv.
Game consoles are best bet.
 
Have a look at : http://retrorgb.com/systems.html
and http://retrorgb.com/rgbguide.html for introduction.

Some of the home entertainment stuff has additional rgb out. They are sold worldwide with minor modifications for local markets.
Those may have a 9 or 15 pin sub-d CGA connector (VGA connector).

Next way is to take a component to rbg cable. That would be somehow contradictionary, but all you need is a signal you can fed to the box. I don't know each and every type of tv gear sold in the states. You have to solder your own cable, i'm afraid.

If all is a no go i'm sorry, i have no more ideas.

Thanks.

I would rather not acquire a game console to test out the converter, though, but that is a good way rule out my *Amiga* as a source of the problem.

In addition, everything I read about game consoles says they use a lower resolution signal than the Amiga. To me that would seem to introduce even more incompatibility.

At this stage, I have asked the seller for a return. If the replacement unit does the same, not sure what to do next.

Ignore the "make an RGB to component cable" suggestion, it's just ignorant!

No purchase. Ask friends, co-workers, neighbours, family members, if they got an old game console stashed away (or old home computer).

The converters when powered up put out an OSD (on screen display) of the resolution as notification.  This lasts a second.  If you don't see it, then it it is broken.  Un-plug the power and plug it back in for this.

The RGB-YUV Converters dont, only the HDMI converters do which use a very basic video processor in them with OSD functionality.
