Greetings,
my PS2 laser died and i had to replace it. I have a V3 and replaced the KHS-400B with an KHS-400C. But now it only reads CD's ( PSX) and the Blue CD's ( PS2) but no DVD anymore. I tried to adjust the the laser and clean it but it didn't work out.
The Pot's are both at 1130 Ohm and it seems that it have no effect changing the DVD Pot. Finally i have tried to use lenschanger but with no positive result either.
Can someone help me out?

you probaply bought a refurbished laser unit which was allready finished off.
i also bought one in the past and it was very crapy too.
Independance exploit will still work.
if he has a big one and a network adapter, then it will be the best solution (my laserQuote:

Then i am probably out of luck :( ...
I am using the exploit because the old laser was already weak, but the problem is that not all games rum from hard drive. There must be some way to get it working, without a laser change ;). I have heard that some V3 do not work with KHS-400C laser units, does someone knows more details on that ?
There is two types of laser diode. They're electronically diferent. New PS2s can use both (V4 or newer) older PS2s have a lot of trouble using the new laser diode. Original lasers which have the new diode have a yellow ring on the lens. Old ones the ring is white. This doesn't apply to refurbished lasers for obvious reasons (chinese people have no reason to bother with the color of the ring as the lens are the same regardless of the color of the ring.)
400C lasers with orange flexible board do have the old laser. All 400B lasers have the old laser as well.
I hope this was informative. :)
Ah I forgot to mention that using a 400C in a V3 will cause your DVD ribbon cable to bend and break...
Thanks for such a detailed reply.
Looks like i have a newer refurbished laser unit. It has an green flexible board and a white ring around the Laser. Therefore i must stick to the exploit ...
If the PS2 (I chipped a V9) is chipped, i found out that not soldering the H point (or by all means - a bad soldering job / a bad wire) makes the PS2 read PSX backups, PS2 DVD's but not PS2 DVD backups! ... maybe some of you got this problem... because on my diagram said that H point is only for NTSC... but I HAD a PAL v9
