That should be it! If it doesn't work you can try to adjust the servo that regulates voltage to the lasers instead but that could fry the lasers out reducing the PS4 to junk! Good Luck! The first thing is to open the PS4 up and blow it out with air from a Air Compressor to reduce the dust, heat, static electricity that dances all over the place because of the dust! Not only does the dust contribute to the items I just wrote above but it also causes tiny electric arcs if there is to much dust on the circuit board too! Remember to first blast the inside with air from a Air Compressor then clean the lenses with an eraser gently, then use alcohol on a Q-tip on both the lenses and metal contacts and blow it all out "again with air" from a Air Compressor! The air from the compressor should dry the 90% or 91% alcohol so that there will be no shorts. Both need to be cleaned by an eraser and then by a Q-tip with 91% alcohol. The Laser of the Blu-ray has actually two lenses/lasers/LED's. Allow to air dry before reassembling the drive.It simple really. Dampen a cotton or foam swab in 91%+ isopropyl alcohol.X Research source More commonly, dust or grime is causing issues, in which case you can clean it: Minor scratches shouldn't cause problems, but deep scratches could require professional treatment.

Some game console faceplates can be removed using pressure from your fingers, but do not apply force unless a guide to your specific model recommends this. Disassemble the drive using a screwdriver.If you're prepared to take the risk, follow these steps: If your device is still under warranty, be aware that this will likely void any chance of getting a replacement or free repair from the manufacture. If the steps above don't work, and you don't want to take the drive to a professional repair shop, you'll need to disassemble the drive and clean the lens.
