When your console does not read any disk, that is usually because of a problem with the
optical laser lens that is dirty, faulty or opaque, and will start
operating on certain disks better than others.
In that case you will hear disk spinning, whirring and clicking, but
the TOC (table of content track at start of CD/DVD will not be read,
therefore the error.
Whe this problem is starting you may be able to read only few CD, DVD.
After more prolonged usage , often the PS start losing the rest of
functions, and ends up not reading anything at
all.
If instead there is no noise, and disk does not spin at all , then
there is a faulty motor, or the motor micro-switch is bad. This
situation is far less common than the lens problem.
Try first using a CD/DVD cleaner disk to clean the lens. If that does
not work you will need to disassemble the PS, and clean lens
directly with q tips and isopropyl alcohol, or to replace the CD/DVD lens, or the whole drive unit.
before doing tis, contact Sony to check if the unit can be replaced or
repaired by Sony, you find the number on the Console documentation.
Things work in the same way on Xbox, Just contact Microsoft instead than Sony.
DVD lens cleaner is not recommended and may void your warranty. A DVD lens cleaner will very likely make the problem worse Sony warns against doing this and If my memory serves me right it might void the warranty as the disc can ruin the lens on the blue ray drive. Disassemble and cleaning the lens is a better option. Even better, just contact sony directly about it, if your on warranty its free repair, outside of warranty its 150 at that point you should try cleaning the lens.
