my previous ps2 (fat one) got problem also. it won't read new game disc. i checked with various shop & they sd probably by 2 problem.
one is the modchip is old & can't play latest games.
two is regarding the lens (already kong).
i tried with new ori game & oso canot play so it's regarding problem no 2.
i went 2 shop 4 repair but they sd the price is rm250 coz fat ps2 parts are xpensive.
so i just bought new ps2 rm500 (slim one).
when i try 2 play, some game won't load then i noticed dat it's not properly inserted (coz we need 2 inserted it manually).
some disc the hole is 2 small so i need 2 make it bigger by knife.
so far my ps2 never got any problem 2 play any games.
most shop that i went 2 repair only took a few hours & the longest time is 1 day.
u need 2 check with dat shop i think coz it's ridiculous oredi 1 week.
