I just got the game god of war, now the playstation2 will not read the disc. why?

Have you tried using a laser cleaner?

a disc used to clean dvd players and cd players?

God of War II being one of the few Dual-Layer discs on the PS2, it is possible that your problem originates from your PS2 lens being unable to read it correctly. The PS2 Slim is supposed to be able to read Dual-Layer, thus you should try cleaning your lens, it may be dirty, leading to this kind of error while still able to read Single-Layer discs.

Your Playstation 2 is having a problem reading the disc because of those scratches. Try to fix those scratches by following the steps from this website : click here. If you want you can also buy cd repair kits to fix the scratches. I checked a website where you can see which commercial cd repair kit is more effective. You can find it in this link : click here
I hope this help solved your problem. Have a good day!

my problem is gs plugin failedto open/initialize

The solution is simple. The God of War 3 demo is a dual disc. When initially inserted, the ps3 will automatically go to the game tab. Scroll over to the video tab and go up. District 9 will play on your ps3! It will say "District 9 Blu-Ray!"

clean the disc and the eye of the playstation with windex

Sounds like a defect in the disc. Possibly a scratch or blemish.
If your other games dont hiccup it's most likely the "god of war" disc

Hi there. Are the older games you're trying to play CD games ? They might be :) The laser lens in such consoles can be fried on the dvd part, but still read CD's. Have you tried, to read a DVD Movie in it ? I bet it doesn't work either. The slimlines are infamous for laser burnout, and god they're quick to burn. You can try to clean your laser lens with a q-tip and some rubbing alcohol, but i'd say you're already out of luck. The optical lens is quite easy to replace in those units. They can be found on ebay and on various websites for 20$, and if you can play a bit with a phillips screwdriver, chances you'll be able to replace it yourself with a bit of patience are good enough. If you need additional help just ask, hope that helps ! cheebster.

the problem with god of war 2 is the ps2 lasers are not capable of reading the dual layer disks. either wait and get a ps3, change the laser - i just bought on for 3 quid on e bay brand new. the lasers are not designed to be played the amount they are played. the laser is designed to play 20 hours a week but as sony found out he avg gamer will clock up up tp 60 hours a week so the lasers are only lasting 1/3rd of the time they should. plus if they put a good laser in the machine u would one buy 1 ps2 and then 1 ps3. i have burned out 3 ps2's so far lol. just forget the game or wait till its put on platinum as these are single layerd disk
