MicroniK Scandex scan doubler Problem?

spawnerbr · 22 March 2016, 09:22

I have a MicroniK Scandex scan doubler that I used a lot on the past. So, I got my A1200 back in action and tried to connect it on my TV PC connector [VGA/RGB].
So, I got surprised because there are some problems on the image like strange bars and sometimes scanlines errors. My 2 TVs fails to show the Amiga image, so I tried on my 2 CRT monitors too and I got the same problem.
Maybe the last time that I used this scan doubler was on a Syncmaster 3NE monitor that I don't have anymore. Maybe a problem with actual techonology?

This is my scan doubler:

These are the pictures from the screens:

Amiga 1200

Amiga 500

Any clues what happens? Thanks.

It was never a great scan doubler. I have one and have had it since it was released. It always had a few dark blue horizontal lines running through the middle of the screen, only visible on black. I could negate it a bit by crocodile clipping the vga ground to a grounding point on one of the unused amiga sockets so there is some grounding issues inside the adaptor I think.

Sometimes I would get vertical lines as well and one of my Amigas wouldn't power up at all with the adaptor connected.

It worked with me on CRT monitors, but when I tried to use in all kinds of LCD or LED monitors, the vertical bars appeared. Only when I use Multiscan Laced, the vertical bars disappeared.
