Hey all. Got a little bit of a problem. Modded a v5 ps2 for somebody 3-4 monthes ago, came back to me just recently because they were having problems. It was modded with a duo2 se. When i first got it, i had to vacuum the system out thoroughly, as it had large amoutns of dust inside. Anyways so they brought it to me because after playing it for 8-10 hours straight, as it froze in game, and it wouldn't load games nemore. So i turned it on, notice on boot up (without disc in) that the system is making a fuzzy/scratchy noise at the screen w/ browser and system config. So i shut it off, clean all the bios points, and once again vacuum the system from the large dust deposits inside and aroudn the bios points. Turn the system on, worked geat for 45 mins, where it then froze in game, and began doing the same thing as before.
So i took the chip out, cleaned THOROUGHLY all points, and changed the laser with another working laser i had here, and notice that after about 20 mins of socom 2 sitting through it's menu and intro movies, it began to make a scratchy/fuzzy sound through the speakers, i shut it off, turned it on and got black screen. Waited about 5 mins, turned it back on, and it once again worked. Now the BIOS points are perfectly clean, and i put a little extra solder on the pins to attach them to their pads. The chip is currently OUT of the system.
Any ideas as to what the problem might be? Thank you so much for your help!!!
