Hello all. I'm hoping someone can give me a little bit of technical support. I have a model 1 sega genesis 1601 that is not working correctly. When I plug it into my newer model Plasma TV everything that should be white is green as you can see here:
I've tested multipal games using the following video cables:
DIN>RCA Composite adaptor bought on Amazon.com
Original RF Coaxial adaptor
Composite MOD from DIN Pin
As you can see, I've tried the video mod using the post/pin directly under the DIN connector on the board. Maybe there is another pin I could try? All of these scenarios give me the "green screen".
Also, I have tested on a friends newer LCD which gives a different result of the screen flipping/scrolling rapidly. Then I tested on a tube TV, and the colors appear mostly correct, but a little off - almost like it's super high contrast, and has the occasional screen scroll. In yet another test in order to rule out the TV, my friends Model 1 Genesis works and looks fine on my TV.
I've visually checked all my capacitors and they appear fine aside from one that I can't tell if it's blown or just dirty on the top - also all my solders look fine underneath. Thoughts?
