Fell down three times and now its not reading any disc but it still working. u can still go online with my ps3 slim(250)

Hello

Check the PS3's vents or its location if the power button alternately flashing red and green. This means it is running hot. Shut it off and wait for it to cool down.

Shut down the system if the power button flashes red and fails to operate. This means it has overheated and has reached a critical phase. Move it to another location where the vents are not blocked and it isn't in an enclosed area. Don't restart it until it cools down.

Open your PS3's disc tray and spray the inside of the machine with some compressed air, which comes either in a can or in a squeeze ball. This air will help remove any larger particles of dust or dirt that may have accumulated on the machine's lens.

Insert the cleaning CD into the disc tray and close it. These CDs often have no data on them and instead have a small brush along the bottom that cleans the laser as it spins over it.

Follow any on-screen instructions or paper instructions that may have been included with your lens-cleaning CD until the laser has been successfully cleaned, and then remove the CD.

Restore the PS3 to its default settings if the PS3 isn't able to read any discs. Go to "Settings," and then "System Settings." Under "System Settings," select "Restore Default Settings" and press the "X" button on your controller to restore the settings. Once the operation has been completed, the initial setup screen will appear.

Check to see whether the machine will load games or DVDs properly. If it still doesn't, you may have an internal hardware issue that requires sending your machine to Sony for professional repairs.
