My V12 slimline PS2 has stopped recognizing any DVD/CD. It simply goes to the browser screen on booting. It was working fine until a few days back. Then I tried to use DVD Region X for playing DVDs. Not only did this not work, since then my PS2 has stopped reading all discs. Is something wrong with the laser? What can I do about this. I hope I don't have to change the lens. It never appeared to give any problems until now.
