i baught a v7 ps2 of my mate hopin i could fix it. When i recived it there were no ribon cables plugged in so i pluged all of them in (the one between the laser and motherbourd is very loose i had to tape it in) after this i pluged power in and turned on at back at this point the restart light goes red like it should but the eject one dosnt light. if i press the restart button it goes green like it should, the fan runs and the tv flickers then goes black again but the laser dosnt make any noise or move at all. If i press the eject button which isnt lighted up it dose the exact same.
the ps11 fuse isnt blown is there still any hance of it being the ba chip if the fuse hasnt blown. also if the ba chip is faulty can i just remove it to see if video comes on the screen which it dosnt at the moment
Did you put the laser ribbon in the right way and not flipped around,there are two browm latches on the bottom side of the laser that have to be released so that the ribbon cable can be seated in there and then the clamps can be closed to hold the ribbon cable securely.
Make sure that the reset/eject ribbon isn`t damaged like kinks or nicks in it as the is a fragile ribbon cable and make sure it isn`t flipped over and plugged in wrong,and check all other connections closely to make sure it is all plug in properly before looking at other causes just in case it is only a plug or ribbon cable.
It looks like the brown clamps are missing as shown it the pic below which is a 400B laser but it has the same clamps as your`s should have but are missing. Also below is a pic of a LA chip which is also the BA chip in older ps2 versions under v9 as you can see that #8 pin is beside the wide center strip of the chip,the BA chip will be the same and if pin 8 reads 0 ohms then the BA chip is no good.
For the laser ribbon cable you will have to just try it and see if the pic i provided helps as i can`t find the other pic at this time.Hope info helps.
from what i understand i dont think the laser ribon can be the problem. because should still be able to boot to browser without the dvd drive there. But if i get this first problem fixed then i will buy a replacement lens cable from divineo.cn. Even though i cannot find anything wrong with the ba chip im going to take it out and see if the ps2 bootes to the browser if it dose il just buy a new one if it dusnt i will probly give up and sell the thing on ebay.
