sounds like fried laser.
Ps2 has two lasers, one CD one DVD. Sounds like yr cd one went first and now yr dvd one gone too.
Either u have old PS2 like a version 3 or 4 and it has come to the end of its life or it has had a few bumps and knocks. It don't take much to damage the laser.
U can get the laser recalibrated but this might not work if it';s totally had it, or u can get replacement lasers.
If u interested in getting it repaired then have a look
HERE or drop us an e-mail
