Hello so Im finally going back to another busted board i have on my bench here and im getting a video ram error. Using a UniBios I get no sounds and missing video/sprites. Traces from the 4 rams around the LSPC2 look and test ok with continuity to the LSPC2
Ill deal with the sound issues later.
I was really just trying to remember which chips on these boards are the video rams. As you can see I have a photo of the rams around the LSPC2
The Video Ram Error does not change its read or writes across power cycles and the address changed once on the last bit from 0 to a 3, but its not reproducible
The astute among you may have noticed the two SMD rams on the left side were replaced with samsung rams of equivalency. Im just worried that i goofed and those are actually color rams and not video ram LOL
Thanks Guys
