Please Help Plzzz its not a crappy post i need help cmon anyone?

[spedmetal]

What laser did you order, and from who?

[seaneyb2003]

400b i checked it all out.

But it still wont read the disks. I think ive messed it up caus i turned the white cog all the way roundd.

[spedmetal]

Take an Ohms reading off the pots and post your results for both the CD and DVD pots.

If you turn the cog all the way, it clicks and lands in it's lowest position. You can turn it back to normal position. As Sped said, post your pot results...

oh i do that tonight when im at home. I know there quite high. on the pot where do i put the multimeter tips on the 2 legs of the pot?

[ottoman]

don't forget to unsolder the two antistatic protection blobs of solder on yr new laser b4 installation or it won't read a thing.

[seaneyb2003]

i will thanks anyway

Hey man. Hope it works out. Laser cals can be a bitch but best thing is to set several hours aside for it.

Quick guide...

Leave pots where they are....Adjust cogs to lowest position and try an original dvd, then adjust up two clicks and try again ...etc.

When original dvd works continue adjusting until dvd stops working. That give u the range of height settings ( measured in cog clicks!)

So, go back to the first cog click that it worked an put a dvd backup in, now try, if it don't work again adjust the cog up and once again find the range that dvd-r will boot up.

Once range found sit the cog in the dead centre of the range, test the cd's / cdr's and check that they still work ( if not a cog click forward or backwards might be in order), test a dvd movie an check that still boots up and yr set.

So, you've gone through the dvd range and no dvd-r boot up........Adjust the DVD pot by 5% downwards in Ohms and then start the cog height adjustment again.

Warning...If u adjust yr dvd pot resistance by more than 10% of the original value then u risk seriously reducing the lifespan of yr laser....I accept no responsibility for these methods and anything u do on yr ps2 is at yr own risk. This is mearly a suggested method.

All very good suggestions, but since he did purchase this laser second hand (not the original it came with) it might be a good idea to start with a pot measurement fist to see what you are going to be working with before hand.

[seaneyb2003]

noooo sped u got it wrong

ive orderd a brand new laser.

The console itself is second hand and the laser in it atm is the origonal. Just waiting for the postman 2 come.

Otto cheers for the advice.

the cog u mean the while cog at the top?

[spedmetal]

That’s what I was referring to, was the one you are waiting for....

[seaneyb2003]

well its being gay

first of all i put the new laser in and i saw the laser been good start eh?

then i wacked a cd in didnt boot ok i knew why. So i fiddled with the cog to see if i can get a reading and i did so i tryied dvd games worked bit slow cd games fine music fine and dvds worked fine a lil slow. So again i wacked it up dvd games were perfect! tehn i booted movies and it wouldnt read it all i could here is clicking

@ Seany - Keep in there, a bit more fiddling and you'll have it. They can be a real pain in the arse...
