Ps2 Laser swap not working out.

[Sophm]

I have two PS2's both model ps2 SCPH-39001. One has the KHS-400C and other has KHS-400R.

The one with 400c laser, the lasers bad.
The one with 400R laser is good but the CPU kept having solder joints crack and I reflowed it 3 times but its finally went.

So I swapped the whole drive with the 400R laser into the the other system and the laser act like crap. It takes longer to read and It makes a high pitch noise when first reads disc. Backup games cut scenes stutter. I used Lens changer and it still has no improvement.

I tried changing lens voltage and adjust the white gear and not much changes. So i reverted them back to original spot.

I cant figure it out why it acts like crap the 400R laser worked great was quite and read games fast but i swapped it into the other system and act crappy.


Thanks for any help.

You need to run the lenschanger program on the target console, and use it to change that console's target laser type to the KHS-400R type.

Do it fast.... before you total that KHS-400R laser too.
You may also want to re-tune the laser's potentiometers and re-adjust that white gear after that too (if you've made some really large adjustments!! ).

I have used the lens changer you must of missed it when reading. I have it programed to 400R laser and I see very little improvement since i change it.

The voltage pots and white gear shouldn't need adjustments I would think, I swap the whole drive bay out. Like i said I changed both and couldn't find a better spot.

I use swap magic and that seems to have hard time of loading and copy games cuts scenes stutter. The 400r laser worked great in the original system I removed it from. Both systems are SCPH-39001 Except laser, power supply board and heat Sink design.

The heat sink in the system with the original 400R laser is junk its doesn't cover the whole CPU I Would say about 1/4 of the CPU is not covered and that's why I keep having to reflow the solder.

Theres a hardware mod for this too,but i never tried it out myself.Dunno where i got it from,but i saved it if you want to try it.Looks like theres some kinda jumper on those motherboards to change laser types.I had the same problem as you and i was going to try this,but i just picked up another console on ebay.

Thanks for the hardware mod.
Not ready to solder something that tiny just yet.

As of now the system is reading pressed disc pretty nicely but DVD-R's they reads but still the FMV still stuttering,they never did that on original console that had the 400R Laser.
