to the Pros (have you seen this)

The LA chip has nothing to do with what laser goes in what unit. The LA chips are in both the KHS-400C units and the HD7 units.

If you got an HD7 laser to work in a unit that originaly had a KHS-400C (or vice versa ) it will work but not well. The KHS-400C will act wacky before it finally starts to read the disc. You will hear loud clicks from the laser trying to focus and it will take a good 30 seconds before it will boot and it will sit at the browser screen while its doing this. Using a KHS-400C in a unit that has a HD7 in it will also wear out the KHS-400C very quickly because of the hard time it has focusing in the beginning of the boot process.]

Partial replacement as in you leave the dead LA in and attach the "partial" replacement. The other 2 I linked to you replace the whole LA.

thank you, Speed!

That clear up alot, just one more question... If i replace the la6508 with the full replacement chip that you pointed out, is there anyway to put the 400c laser into the ps2 with the hd7 originally? and have it working good? Thank again.

btw, when it tried the hd7 in the 400c ps2, the dvd spin up alittle slower but it seems to boot as normal, it seems pretty fast when booting and loading...how is that possible?

No, not that I'm aware of.

Hmm... no idea, luck I guess. Never worked out like that for me or any one else I have spoken with about this same issue.

Now I wonder if it work if i was to swap the khs-400c laser into the hd7 system after I replace the la6508? 'Cause if it works, I may have stumble on something interesting here...

Has the LA6508 blown in the first place?There is no point in replacing a chip which hasn't blown...

I think so, the la6508 in the ps2 with the hd7 is burned out otherwise that system would have boot with the hd7 in it. I also tried to swap the "burned out" ps2 with the 400c laser and it acted weird when i tried to boot up. The laser clicked like nuts...
