    hello,
    i have an aiwa cd stereo system (model xr-em50) that works great - except the cd player. it plays a cd then wont be able to read the cd with a message " no disk." if i buy a new cd, it will play it off and on. when it's playing, it sounds really good. it's just a question of getting it to read all cd's. i have tried cleaning the laser disk, etc - but doesn't make a difference.
    any ideas?

    Did you try to clean the lens? Another test is to tilt the player 30-60 degrees (forward, backward, sideways).

    Resqueline ,
    thanks for your reply. i did try cleaning the lens...nada
    i just tipped it to the side, front and back like you advised and it seemed to read the cd - although it makes a high pitched sound while spinning - question is how to eliminate that sound. and how often to tip it...

    it has seemed to go off again and doesn't repond to tipping it any direction now. that's the problem- it's inconsistent. don't know what else to try. perhaps the lazer lens is bad?

    The tilt test is supposed to be done while attempting to play to see if it will play reliably in any position other than horizontal.
    It's a test that will reveal possibly worn-out spindle bearings, as well as possible tracking offset errors.
    I have no idea why it should start to make a high pitched sound after being tilted and not before.
    The sound may be emitted by an overly "nervous" tracking system.

    it does play when tilted with the cd's it can read. could this be a matter of replacing the laser lens? and if so, what are the costs involved?

    Ok, if it always plays while tilted (any way) then the spindle motor bearings are shot. Replace the spindle motor, it should be quite cheap.

    here's the thing...it doesn't always play while tilted. it can read only a few new cds and not most others. i have tried the cd laser lens cleaner and it remains the same. if the unit is on for a while it will not be able to read a cd...unless i turn it off for a while.

    I will be honest... I don't know a lot about laser reading... but I have fixed a couple of PS2's with similar errors... could it be a laser lens misalignment?

    might that be why it is inconsistent in reading cd's? and if it is a case of misalignment, is that an easy correction to fix?

    well, as far as alignment goes, I am honestly not too sure, it very greatly depends on the actual player itself... I have honestly not done any of these kinds of alignments I have only done the ones on a PS2... and those are very time consuming due to how it is supposed to be tested.

    I know there are repair shops that can still do that kind of stuff... I don't know exactly what is required, but I am pretty sure something specialized is required, the way I did it with a PS2 can be found here:

    http://arstechnica.com/gaming/guides/2003/11/ps2-repair-guide.ars/

    Keep in mind, this general issue with PS2's is only ONE level of alignment, I believe it would be the "z axis adjustment" IE: how close the lens is to the disc.

    but honestly not many things look even REMOTELY close to this, and the reason why its time consuming is that I never had anything really precision enough to do this job correctly.... is was like taking a machete and trying to clear an acre of brush.... you may be able to do it, but it probably won't be worth your time.

    Either way, I wish you good luck in your ventures!
