sounds like ur ps2 craped out alot of ps2 do that they just stop reading dvd games dose it give a disk read error sony is bad about haveing problems with systems doing this alot of people on ebay sell there systems that r broke that do the same thing u could try getting another laser installed but thats hard to do if u dont know what ur doing . and so much for sony fixing it they wont fix systems that has a mod installed maybe if u take out the mod then send it to sony they may fix it say u bought it off ebay as a working system and u got screwed and it dose not work they fixed mine for free cause i told them that
or 2nd do the wal-mart switcharoo buy u a new system carefully open the case with out damageing the void sticker take the insides out put ur old insides in the new systems case and the insides from the new system in ur case take back and get a refund
or 3 u can just buy u a new system heard aftr the 15th price said to drop to
150$ for both ps2/xbox and belive me the chip was not the death of this system cause alot of non moded ps2 do the same thing
