Hmm, so I assume you're referring to actual tray alignment, if you're referring to the white cog wheel. You said you spun it around twice, but that's a bit too vague. When setting tray alignment you have to only turn that cog wheel one click at a time. Put your game in, test it, then if it doesn't work pull it part, turn it one more click, rinse, repeat. Now if this method is what you're referring to, then here is what's goin on. If the motor was damaged you wouldn't be hearing any clicking, that's incorrect. That clicking noise you're hearing is in fact the laser lens eye hitting the disk itself because it is trying to read and can not. But this is too vague, you first need to define what it is, and is not reading.

FIRST (if you've done the tray alignment trick as you stated above (hope you set a mark of some kind to set it back to where it was before) set it back to the position it was at before you first started tampering with it)

SECOND clean your laser lens, just cuz you don't see anything on it doesn't mean something isn't there. Cigarette smoke creates a gloss over film wich is almost naked to the users eye. So strip down your PS2 open up your dvdrom and find the laser eye, take a cue tip and 20% rubbing alcohol to 80% water, mix well, and saturate cuetip and go over the laser eye with that solution. Put in a a game and test. If nothing happends and game will not read then move to THIRD step.

THIRD go .::HERE::.

Follow my commented instructions on tests with regular non burned media to deduce if the lens will even read anything at all. Test DVD's (game and movie) and Playstation 1 games and Music CD's (NON BURNED - RETAIL ONLY). If my guess is correct, as with 99% of everyone's PS2 woes on disk reading. Your PS2 is playing music cd's just fine and prolly playstation 1 games just fine but not DVD material both movie or game.

IF your PS2 reads no media at all, AND you have tested every single cog wheel notch then more then likely your PS2 laser lens is damaged. Or the potentiometer pots on the back of the lens itself need adjusting (go to that link i posted above and follow the links and read what i posted there on this subject) in short there are two screws on the back of the PS2 lens one controls the power of the DVD lens one controls the power of the CD lens. These voltage regulators are the LEADING cause to PS2's lens failure on certain if not all media. That motor statement made above makes no sence at all. No offence Ryd66 but you wouldn't be hearing this clicking noise at all if that motor was burned out. It wouldn't be moving the lens in the correct position in the first place to even create the noise(in this case the noise being the lens eye hitting the disk surface, in an attempt to scan for media) in order for the lens to produce this noise the motor MUST move the eye to the inner position cuz that's where all disk reading starts. It would then run the media check to deduce what type of media it's dealing with(cd or dvd), then once it's figured that out it would move the eye again to the first entry of the LBA to try to read the media itself. It's usually in this stage that the clicking would happen as it's trying to read the data from the disk. The laser assembly moves on the glide rods from inside to outside several times to even read a media disk.

But you don't have to take my word for this, you can easily prove this yourself visually. Take apart your PS2 take the screws off your DVD-ROM and remove that plastic plate. (if you have a slimline model just open the fliptop and remove the white magnet in the center of the lid of the dvdrom cover) once you have the plate removed remove the white round magnet plastic piece. Now put a game or dvd on the tray(if you use a game, for the purpose of this test use a PS2 game cuz it's in dvd format) itself and place that plastic piece on top of the disk. This will hold the disk into place. Reason why you're using a PS2 game or DVD is cuz DVD mode laser eye uses more power and you can visually see the laser lens moving up and down the disk when you power it on, you'll see the laser almost appear through the disk itself. Next, power on the PS2. If you see the laser moving the motor is working just fine, if it doesn't move at all then yes the motor is damaged.

Once you've varified that it's not the motor then that leaves only one(two or all) of three things lens Alignment, lens Voltage, possible lens damage. If you've tested every single gear on that cog then it's not alignment, it's voltage. If you've followed my post(above) and reset your voltage to factory default and it's still not working then the lens is damaged and needs to be replaced.

Hope that's of some help,

Hmmmm, Then poissibly the motor might have a need for servicing. Because by the sounds of it, the motor isnt moving quite right inside the system. I ran into this problem with my PS1 and PS2's that i have had over the years. Motors can wear out over time and use. If your like my friends, they go through a new PS2 in a year flat, because it is used 20 to 22 horus a day by 3 different people. So yeah, they use theirs very well.

Back to subject. Anyways, if the motor is not actually doing much but clicking, it sounds like there is an Obstruction in the way of the spin. Meaning, its not getting its complete rotation every whatever amount, so it will not read the disc. The motor also has to be able to move back and forth to read the disc as you play it and if that motor goes, than you rarely can play a game all the way through.

There are usually a number of computer stores (small time) that offer repair services for a price. They can usually order the small parts and Sony lets them install those replacement parts, because like all big companies, it takes a lot longer to get things done because everyone goes there first.

When searching for a store that can help, be specific in questioning. You need to ask directly if they have any employee's who know how to service PS2's

Getting a disc error when turning on the ps2 with ps2 games, but it works with ps1 games...!

Theres a wheel in the disc drive that controls the elevation of the lens. To mod your ps2 to read burnt ps2 games ONE would alter the height of the lens by adjusting the wheel ever so slightly. There are online tutorials in the precise adjustments for different disks. (one height reads only ps1 games, another height reads ps1 and ps2 games, and one more height reads ps1/ps2 and burnt ps1/ps2 games) Your best bet would probably be to just purchase another ps2 used, but if you want to do it yourself, you can.

No Valid Disc

I had tried cleaning the lens like most solutions said to do, with no luck. I tried what user gthumm said he/she tried, which was taking off the back of the player. Their problem was the white wheel (motor) and the next wheel (black) were not turning smoothly. He/she pushed the white wheel down until it snapped back in, allowing the wheels to turn. I tried it twice and finally, I have a working portable dvd player again! Yeah! Thank you so much gthumm and fix ya team! My kids especially thank you! You are the BEST!

Disc Read Error

There is not a way to keep it from resetting, however it does sound like the lens is bad. Since it sounds like you have no problem working with them you can get a new lens cheaper than buying a new machine. The 30001's had 2 or 3 different type lens in them. You can seach ebay for them, they are normally for sale there around $40-50 last time I checked. Since cleaning and adjusting does not fix it, I think this is the last resort, other than full replacement of the system :-) Sorry....

Dodgy ps2!!!

yeah your laser is out of line. to correct it you have to open up your console a bit. Pull the rubber feet off the bottom and unscrew the shell, be really careful when you take the two halves apart because you have wires running between them. Then unscrew the black plastic cover over the drive and underneath you should see a large white gear with a slot for a hex key in the middle. Mark off the start position on this wheel then move it clockwise by one cog, close it up and try a disc. If it doesnt work, move the wheel round one more cog and try again.

Remember different types of disc work differently, the PS2 reads PS1 games easiest, then DVDs, then PS2 silver discs, then PS2 blue discs, so try them in turn.

If you look hard enough on the web there is a detailed explanation of this repair with photos that is worth seeking out

PS2 Read Error

I hope your in the right posting area, this is for the Phat PS2 consoles with the drawer that comes out to put the CD in. Procedure is different for Slim PS2.
  1. Disconnect power and turn the case upside down.
  2. Remove the screw covers to expose the case screws. These are little square pieces or square rubber pads. You can use a thin knife blade to pry the hard plastic squares up.
  3. Remove all the screws.
  4. REmove the Warranty sticker to the right edge of the power socket.
  5. Turn the PS2 over to set it right side up.
  6. lift the top cover from the back and pull it forward slightly to clear the CD tray. Be careful of a possibly Ribbon cable attached to the lid going to the REset/Eject buttons. Roll the cover over to the right leaving the ribbon intact.
  7. Remove the Cd tray lid.
  8. Polish the Laser lens, and remove any lint or hair from the Cd area. Use Alcohol and cotton swabs to clean the laser lens. By the way, Alcohol will damage a PS2 Slim lens. All lens are not created equally.
  9. Hook up the power and A/v Cables.
  10. REmove the little white disc from the Cd tray lid.
  11. Place a Disc on the spindle, and cap the disc with the little white piece that you removed from the CD tray cover.
  12. Boot up the PS2 and test it, Continue cleaning until you get it to work.
  13. Put it back together, and your in business.
If you have trouble you can send your PS2 to the Playstation Clinic for Repair. Contact
