Sounds like something is not properly installed.
How is your ground wire? Thick?
Yes, you can see on chips when u turn on ps2 that the black screen is a little longer and it flicker ones. If RSOD u should check DVD/CD points a,b,g,h,i, and such.
If BLACK screen check bios points.
U can disable H20 by holding in RESET. This is also a good trouble shooting method. If the console boots disabled, u know there aint no bridges but something is ****ed up on the bios points most likely.
Ive troubleshooted like that on mars and magic s+. I had lot of probs with black screen with magic s+ (shit chip! worst ever), but never had any with the h20.
Hello. This is my signature. Nice? yeah? Thanks!
