I have been enjoying the Indivision ECS V2 for a month now. This morning I switched on my amiga 500 (rev6a) KS1.3 to discover a black screen. I can insert a game in the disk drive and it loads & plays the game music. I tried a scart cable through the RGB video port and it displayed the games graphics. I have also tried reseating the ECS V2 but still get a black screen.
