Hi there,
Because finding A/V cables for the Megadrive 1 has become all but impossible in the Netherlands I decided to do some modding myself. So I bought a female RCA connector, looked up the pinout on the web and got my soldering iron. I connected the 'tip' of the connector to the pin on the A/V connector marked as composite and soldered the edge to a piece of silverish plating on my Megadrive's PCB (later I tried different points for ground).
When that was done I hooked the thing up to a rca-to-scart converter and tried it on a TV. The display looked extremely odd, it was grayscale, several parts of the screen were scrolled vertically, some was garbled and the Megadrive crashed after some time (don't think that has anything to do with my soldering, though).
So I tried it on another TV, it displayed a rapidly rolling black-and-white image (only black & white, no grayscale this time). On my TV card it was even worse, I only got a display one line high and the rest was the blue color you get when there's no signal!
Now what did I do wrong? |
