New Amiga RGB To Component Video Adapter FINISHED!!!

[mindprober]

I see your imbedded image link when quoting you but it did not show up in the original post. Weird.

Silly question, but if you are looking for correct voltages, I assume you want the DB23 side plugged in and the Amiga turned on before I check the SCART side?

In that event, I had better be careful where I am sticking the voltmeter probe.  

Scart pinout



Check on cable (not box )
Pin 20 --> should be less then 3.0 V
Pin 16 --> 5.0 V
Pin 8   --> 12.0 V

Final test Pin 13 on amiga sub-d 23pin should be wired to pin 18 scart only, no other ground. if it is grounded to shielding(common ground) or all other ground, isolate or cut and rewire.

i hope this will help

Yes, connect cable to miggy or you don't get anything interesting

I figured but it doesn't hurt to be certain today given my diminishing attention span.

I must be doing something wrong because I am not getting any voltages off of those pins! Yes, the computer is turned on.  

Granted, it has been years since I have used my multimeter but I did do a quick test on a battery and the reading was accurate.

I placed the common probe on the common ground (pin 21) and the "hot" probe on the various pins. Please ignore the "200" setting in the attachment. I had it on 20 when I was testing.

I also tried the shield ground instead of pin 21. It did not help.

Do I even have my "hot" probe plugged into the right socket on the meter? Probably do since the battery gave me a reading.

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.

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.

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.

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.
