Did the game start or not?

So I'm lost at the same point with my Stargate...somebody told me to change U4 but you says that it don't work...I'll bought every chip this afternoon and tell you what it done...already change U3 U8 also U5;6;7 U16;17 and every other component at it is required when unplugged DMD.
My post is called Gottlieb garbage DMD

I've change U4 for beginning and it work a little bit better with moving sequences...
After change U1 U9 U12 (forget U10 an U11 see that tomorrow) U13 U14 and U15 nothing better
I'm on the good way but enable to buy U2 at market...May be on the web

Better when I change the big one U1 so I think U2 need to be change but not even U5;6;7 U9; to U12, U13 to U17
Good luck

So I replace every chip on this card and still garbage when playing scene from the movie...I'm thinking that it may comes from the DMD itself cause I ears some noise coming from it just when screen blinking. It may had trouble when did a bad replacement on A5. As it is out of gas (probably the original one) I will change it as soon.

Good luck
