As I said in my presentation topic :
I've got a 7800 with some video problems. I hope I post this topic in the correct forum.
Here's the problems :
When I play a cartridge (2600 games, I don't own any 7800 game for now), the display is dominantly red/orange, with very visible scanlines (like a very bad filter in some emulation program) and a bit blury too.
When I play the internal 7800 game (asteroids), the problems are less important, but the display is still far from being perfect (especially the blur).
I tried to move the video cable to see if any diference appears : no diference. So I don't think it's the cable fault.
So I dissassembled the console. The video female plug seems in good shape, with all pins firmly attached to the daughter board. The weld points seems a bit dry maybe.
I also tried to move the 2 "knobs" on the daughter board, with apparently no effect (difficult to see, because of the awfull red-ish blurry display).
Now I'm a bit lost, so I think I'll start by doing new fresh weld points for the video plug. Any help will be appreciated.
Many thanks !
