If your Sony PS2 Slim console (SCPH-7000X/7500X series) is having trouble reading CD or DVD games, movies, or audio CDs, it's time to replace the laser lens. This replacement laser lens (part number SPU3170) is designed to fit many models in these series. It's a previously used but tested working product, with some cosmetic marks or signs of previous use, and comes with our 2-year warranty. You'll need a soldering iron to remove the anti-static point before installation. Disassembling the console is necessary for installation, which will void any existing warranty. Check compatibility before purchasing. To identify the region, look at the last digit of the model number: 70001 = US, 70002 = AU & NZ, 70003 = EU, 70004 = UK. The region isn't crucial for laser compatibility but can be confusing when ordering parts. Tools like a soldering iron and basic screwdrivers (not included) are needed for installation.
