Wont load disk

If your PS2 is made pre-2009 (has a manufacturer number less than 9xxxxxxxx) then you can use a bootloader to unlock the USB and hardrive to play "backed up" games and AVI movies.

You will need on of these things:
1) an original copy of 007 Agent Under Fire or an original PS1 game, to use as a "trigger" disk.
2) a original copy of Gameshark, SwapMagic, or CodeBreaker for PS2 (DL'ed copies wont work)

and you will need:
1) a memory card plugged into your PS2 slot 1
2) a USB drive

Now do this:

Load the boatloader ELF file from a burner "backup copy" of your 007 disk (using the "disk swap trick" on your "sensor-modded" PS2. I used ESR Disk Patcher and Apache V1.1 to alter the TOC values of the ELF file and "patch" the ISO file before burning, and I used the disk swap trick after playing level one of the game, saving, and then loading the "driving level" (level 2).

OR use SwapMagic or similar tool to load the bootloader. You can find Youtube videos detailing this process.

Install Free McBoot onto your memcard using the bootloader. You can use the "noobie package", use google to find this and put the files onto yor USB card. Voila! Now you can play AVI files or "backed up" games from USB or hard-drive, among other fun things.

try a WET cleaning disk

HI, the optics assembly has failed. the actual optical lens assembly will need to be replace in this case. you can try to clean the lens with a cleaning disk.. this may wake the laser. if the cleaning doesn't produce results, replacing the optical lens assembly will be the next move.

please tray your ps2 disc format pal with another ps2 console if still can play game sure your disk err

there is probably something wrong with the lazier i would go the radio shack or taret to get a dvd lens cleaner for your ps2 disc drive

maybe the other disks are scrached

go on to www.swapmagic3.com and have a look at the website.

ok maybe your laser is dirty - buy a disk cleaner (a disk that has brushes to clean laser)

Did you remove the anti static solder blob (point) on your new laser with a soldering iron and solder wick prior to installing it? The symptons your explaining indicate that point is still intact, If so you will need to carefully remove it first then reinstall the laser and try again.

First of all the new laser lens will not allow your Slim to read NTSC UC games if you have a PAL european Console.

There is no reason the New laser should have not read the disc unless it Came to you damaged. It sounds like you know how to replace a laser.
