The PS3 Blu-Ray drive can still read DVD's? What about Blu-Ray Movies? The laser diode in the drive actual has 2 laser outputs, a red laser and a blue. The red laser is used to read DVD's & CD's, while the blue reads games & Blu-Ray movies. Most likely the blue laser is damaged as it is much more sensitive to heat. The solution is replace the laser $@!'y in the drive. Be sure to get the correct assembly, you can identify the drive by its model number inscribed on the laser & motor is mounted on.
