Repair not for beginners

The article is consistent with the description and change of this piece in my PS3 slim has remedied the non-problem of playing DVD, Blu-ray.
Nevertheless, despite what I've read, making the change of this piece is not easy if not we are used to dismantle electronic devices.
For those who have never dismantled anything, I strongly discourages them from themselves this repair. There is too much risk to wrong disassemble / assemble something and make it permanently inoperable PS3.
If you are in the case of a person without experience disassembly / assembly / repair of electronic devices strongly prefer the solution to completely change the Blu-ray player. You'll have more chance of success.
