I have a slim PS2 - SCPH 70006 (a modified one) I bought few months back and been using the "backup disc" for few months including dragon ball and winning eleven.
Alll of a sudden, it cannot read disc. I took to the repairman, and he said that the optical head aging and not have enough light. He replaced the head. It "worked" again.
BUT , I could not really play the Dragon Ball disc as before. In the last 20 tries, I can play 3-4 times only, other all "unable to read disc". For the other like Winning Eleven, it is noraml.
I am trying to fix it. BUT... few question I cannot answer.
If during the first failure, it is really due to the aging optical head, why it broke down so sudden. As the repairman said the light is not strong enough. I expect I should experience some problems before it became faulty. It was really a sudden thing when I became fautly, no previous malfunction at all.
The second thing is that why it can read the "backup" Dragon Ball from time to time initially. But now it basically cannot read it at all for the most recent last trials.
Any master can answer my questions ??!!
