Yeah, after all my reading about mod installs. I still am not quite sure on how to check the LA chip. If it is the LA chip...good luck replacing it. It's a pain in the ass. I'd rather install 10 mod chips in a row then try to replace that darn LA chip. Try ebay for the mother board though. Sometimes you can get some pretty good steals. As you can tell, I gave up on my issue of fixing my ps2. I've posted it on ebay twice now as broke, and both times, the winning bidder never paid. So there it sits. I suppose I can use it for emergency parts.
