Disc Read Error!! HEEELLLPPP!!
 

I recently installed a NEO4 MOD in my PS2
SCPH 30004 v3

After the installation the PS2 started normally untill the BRowser screen.
when try to boot a CD I get an disc read error. With every disc; PS1, PS2 , Audio,
Original or Backup. I removed the 4 points for the DVD function.
Points 38.39.40.41 on the Neo4 chip. After that I only got a black screen.

Someone told me that I have a dry solder somewhere. Or does somebody else has an other idee.

CU

I hope someone with a NEO4 can help ypou but it is obvious to me that you need to go over the 44 solder points again with a map and a magnifying glass.
