Hi all,
I have an offroad board I'm dealing with I'm hoping someone can point me in the right direction. This board originally wasn't booting at all. I went through the entire board with a fine tooth comb and found all kinds of mess ups. I found small bits of copper wire all over the board, and also found one chip U21 to have a bent chip leg and wasn't seated properly into the socket.
After re-seating every chip and cleaning all the sockets i've now got the game booting however there still seems to be an issue with the vertical positioning of the gametrack (not the cars).
Here's what I mean:
I've gone through the service switch diagnostics and everything shows good. I just wanted to confirm my next steps. I've checked out the schematics and there is one section called "Background Vertical Address". Can anyone confirm if this would be a good place to start checking chips?
Thanks in advance!
