v9 help needed

**mann75** · 01-19-2006,02:48 PM

ok i have the scph 50001 series ps2. now the problem is that one day while playing my game it froze i tryed to turn it off by the reset button but it didnt work, so i manually turn it off by the switch. i realized that my laser melted (hd-7) i replaced it with a new laser now it loads fine up unto the matrix logo and then nothing but a blank screen what is going on with my ps2? i know there is a fix for it the romeo but thats only for the v12 not the v9 am i correct? any help would be appreciated.

the romeo fix is for v9 not v12. it is were you lift pin 17 (i think) on the la chip and solder a wire to it and a 5 volt point. but this wont help if your ps2 is alredy gone it is to stop it doing this. your la chip is probly blown it is a very comon problem. to test it use a multi meater to see if pin 17 (i think) is grounded

so once its blown its over?

no its not over, you can replace the la chip to get it back up and runnin again
do a search for the romeo mod and the tut will give u all the info

ok found out its not a bad la chip. for some reason the ps2 no longer accepts the dvd's that i once have after reburning afew i have a new list od dvd-s that it will boot with no problems.

maybe the laser needs retuning - it should boot all the copies. unless they were on dodgy/scratched media.

on a side note - i've replaced a few la's. all bought from divineo - installed with no problems. on just about all of them the laser coils were low, replaced laser - still didnt work, then replaced LA then it worked fine. its very difficult to detect a blown LA (apart from a huge hole in it) - the power pin rarely shorts to ground so there's not much you can measure to detect if its dead.

make sure you use good media and not crappy media, i suggest TY media

**mann75** · 01-20-2006,12:33 PM

yeah it was the media but its funny how it use to work on my old laser and now after the replacement laser is in it stops working on alot of my game disc.

it is prboly because the pot on your newer one is set difrent and is restricting the voltage more
