Bad picture on RGB on ReAmiga 1200 with D520 or other external units.
If you are using a external scandoubler or similiar. like the D520 and get a bad picture, no picture or weird colors on your ReAmiga 1200.
This can be that the “buffer” of RGB signals is screwing things up. so here is a quick description how to remove that and fix the issue.
First locate the components for this:
you need to remove those 3 100 Ohm resistors and the 3 PNP transisors like this:
When this is done, you need to solder 3 resistors that is 0 ohm crossover the 2 pads on each transistorpad like shown on this picture:
When this is done, it will work much better and your D520 etc will work as it should be.
