PS2 slim v12 fried laser
PS2 slim v12 fried laser –
CC installed and fix applied (don't remember which one, though) about a year ago. Running fine until last week then the laser went. Replaced laser and the laser seems to be working now.....I mean I can see the red light......but it won't recognize any disk. Is there something else that needs to be done when replacing the laser? I used to have a v3 and replaced the laser several times in that one and was quite comfortable with the the two adjustments necessary (azimuth and white cog), however I don't see anything like that with this new laser so I don't think there are any adjustments that can be made. Is it possible that I got a bad/weak laser as a replacement or is there something else I can look into to explain why the laser appears to function but won't recognize any disks?
did you unsolder the solder bridge
Is there a solder bridge on the new v12 lasers like there was on the older fat model PS2 lasers? I looked at the underside of the new laser and I didn't see any obvious solder bridge that needed to be removed. Would the laser even produce the red light if the solder bridge was in place because it seems to produce the red laser light just fine, it just won't recognize the disks.....like it can't focus or something.
its on the side and yes it would have those symptoms
Thanks for the help.....much appreciated. Unfortunately, it appears that the solder bridge has already been removed (when I compare with the old fried laser, it looks exactly the same). Any more suggestions?
if that solder bridge is already removed then it is obviously a 2nd hand laser so quite possible it is no good.
is it the same laser, did you change the laser itself or the whole laser block thats held in with the 4 screws.
there are different lasers
Same laser as old one, KHM-430, and it is the entire laser block....not just the laser. I was thinking the same thing about the solder bridge, but the website where I bought the laser from mentioned that they removed the solder bridge as a courtesy to the customer, which was why I was unsure where exactly the bridge would be since it was already removed. Does that really mean they peddle second-hand lasers and are saying that to fool the customer.....hard to say. The laser block certainly looks unused, but I suppose anyone could clean it up to make it look new again. I guess I am wondering if a fried laser could also mean another component failed when the laser went out so that is why this new one isn't working. Although, the laser seems to work just fine, it just doesn't recognize the disk. I will email the merchant to find out the story on the solder bridge.
the soldering bridge is ther to protect laser from ESD. re look over your install and see if you cut the track. I had a V12 that someone had done by another LA installer with an H20 and did not cut track killed laser in 3 months and the rsf200fs is damaged but still working now with new laser and cut track..
