Playstation 2 repair

[Fritz]

Hi,

I'm trying to repair a PS2 console which is not reading either CDs or
DVD discs. So far, I've tried adjusting the laser height/angle and
I've also adjusted the pots on the laser eye itself. Sometimes the
disc will spin when inserted, sometimes not; but it won't read any
discs.

The unit will click when I insert discs as it tries to read them. I
am not familiar with class 1 lasers; I don't know whether they are
supposed to emit a visible beam or not, but if I close the tray with
no disc inside, I see nothing emitted from the laser.

Is it time to change the laser assembly in this unit?

Thanks,
Fritz

If you screwed with the adjustments, it is time to replace the laser
assembly.
Then you can start troubleshooting what might have been the actual failure,
using proper troubleshooting methods and the service manual.

That's what I figured, I will probably replace the laser assembly
next.

For my own curiosity, does anyone know how difficult it is to replace
only the actual laser diode in an assembly such as this?

I'm trying to repair a PS2 console which is not reading either CDs or

DVD discs. So far, I've tried adjusting the laser height/angle and
I've also adjusted the pots on the laser eye itself.

The angle adjustment for the traverse is easy to correct, but you also messed
with the pots for the laser gain of both the red and IR emitters, which is not
good at all. You probably just made something that was likely a simple problem
much worse now.

The problem may have likely been dust accumulation, which means that you would
have to airblast the entire drive clean of any dust as well as airblasting the
insides of the optical pickup. You would also have to relubricate the sled
path and kicker worm gear with low viscosity grease, such as molytone.

In the case of PS-2s with the Sanyo pickup, a metal peg to the left of the
white traverse tilt adjustment gear sometimes pops underneath it. You simply
reposition the peg back into place on the gear's teeth and align the peg
between two alignment holes on the gear.

Is it time to change the laser assembly in this unit?

I'm afraid so, if you can locate a source for it. However, if you marked the
old adjustments on the pots and are able to reset your tweaks, you might be
able to recover it. That is, provided that the lasers aren't damaged.

There have been two different makes of pickups used in the PS-2, both using a
dual laser/single pickup configuration and are easy to identify.

A Sony pickup can be identified simply by looking on the top of the pickup and
observing the "SONY" brand molded on the top of the black pickup housing next
to the objective lens.

A pickup without a Sony brand is the Sanyo.

Beware of counterfeits and reconditioned pickups. - Reinhart

Its very easy toput in a new laser in your ps2 & they are about $50.
