I have a MI green dot installed in my ps2 scph 77001a Gh051-12.It worked for a week and then it started having problems.If i turn on the ps2 it doesn't show me no video. So i resoldered the bios wires and that seemed to fix it for a couple of hours. Then it started not to show me video again. So i resoldered the whole chip and it worked for a couple of hours. Then it started again.So i resoldered the bios wires again and that seemed to fix it for a couple of minutes. Then it froze in a game and when i restarted it it didn't show me any video.So i did the same procedure. Now sometimes it boots but if it boots the sound is f*cked up and if i insert a back-up it says that it is a dvd video and that the dvd player is not set up. I have checked every wire atleast 5 times. I know that the fan is spinning. I have tried with different cables and different TVs. My FW is 1.93.
