To cut a long story short I have a PAL (AU) V12 slim line SPU3170 G wide laser in a customers station that has had its' tracking coil go open circuit not short circuit.
I would suggest that this is a Sony manufacturing fault... (or extended play by the customer of GTA:SA on poor quality media)
To fix the problem I first bought the PVR802 narrow lens only, from Divineo china discovering on delivery that it is around 4mm shorter... i.e. not wide enough to fit between the guide rails of the existing laser...
Not very happy as they were supposed to be universal... I still continued and bought a full optical block this time to get around this problem - again from Divineo china... (this one comes complete with its' own rails and motors)
I installed it last night (yes I removed the shorting links) coils are fine still - 5.1 and 5.7 ohms. The disk spins now (which it did not before) but no game loading... no data recognition on either CD or DVD media...
Browser still appears and works as per normal but as if no disk has been loaded.
Checked the old laser pots:
SPU3170 G CD = 268 ohms
SPU3170 G DVD = 1k ohms
New lasers (Lens and full block lens)
PVR802 CD = 432 ohms
PVR802 DVD = 903 ohms
ob802 CD = 304 ohms
ob802 DVD = 915 ohms
My question is - should I play with the pots?
Should I remove the Summ0ne fix 4.7K on the focus coil?
I have done them in the early days just using the 560 ohms on the tracking coil and they are still working fine...
Do I need to remove the entire summ0ne fix to get these new lasers to work? (or is that to dangerous?)
It is just that from what I have read people who have issues with the summ0ne fix don't even get the CD to spin. My issue seems to be more that it just can't read the disks...
Or is it just another bad buy and is the PVR802 laser totally not compatible with the SPU3170 G laser based stations?
Please anyone who has installed one of these replacement lasers - did they work first go?
Did you have to adjust anything?
Help? (Thread stuck for now - as answers may be useful to other members)
