Video Magician videoslot scandoubler, very dark picture

[keropi]

I received an A4000D with a "video magician" videoslot scandoubler



(http://bboah.com/cgi-bin/showhardware_en.cgi?HARDID=359)
the problem is that it outputs a very dark picture... tried 2 crt monitors, they are the same... there is an adjustment screw on the scandoubler, that fixes brightness, but only a bit, it is still unusable... the card looks OK , there is no visible damage...



there are 3 switches on the bracket , but they make no difference...
anyone else has this sd??? :getmad:  the seller says that if I connect the sd to the picassoII+ input that the amiga has, output will be OK... haven't tried it yet since I left the amiga at the office, but that does not sound good to me LOL

yes, 3rd one , BUT I already donated it for testing purposes to a friend that repairs some hardware in Greece

the adjuster is behind the vga-out, next to the 3 capacitors... it moves only 3/4 of a turn and adjusts brightness ONLY A LITTLE...

have not tried svideo/vhs yet... and I have no idea about the jumpers or the red connector...

the card is the same, but mine has ALL chip markings deleted... I will check the jumpers just in case  :-D

edit: there is a manual here in German: http://amiga.resource.cx/manual/VideoMagician.pdf
it appears red is CVBS and jumper1 is flickerfix on/off...

all the jumpers are in place fine, will test it now on my grex A4000 , in Arxon's place

edit: tried it, still same dark pic... damn
