I have not played my xbox in over a month and then one day i decided to play it and I only played for about an hour or so and than boom the next day i turn it on and it says that the disc is unrecognizable is it possible that dust build up over time then when i turned it on it stired it all up and then set on the disc lazor or what i neeeeedddd heeeeelllllppppp
PS: ive tried more than 12 games and they dont work and even tried them on a different system and they do work
Compressed air or one of them DvD drive laser cleaner discs. There are guides available to adjust the power of the laser which could also be the problem, but you need to be well versed in electronics, as setting the laser output should be done by some one who knows what they're doing, even though the guides will tell you what to turn where, there's no guarantee you won't burn out your laser or something worse by doing it. The best bet is to call around for a shop that can fix it, or send it back to M$.
In order to replace the DvD drive in the system, you need to pull the key off the old drive and put it on the new drive, this requires special software in the best case, and special hardware and software in the worst case(they have different DvD drive manufacturers, and it depends on the manufacturer whether or not it's easy, or relatively easy.)
Thanks you guys I took the whole xbox apart and then took the laser out and cleaned it and blew it with compressed air and put everything back together and now it works !!!!
Good to hear! A few years back I had to rebuild my original Xbox because of all the dust buildup, seems to be a tradeoff with small console cases, always fun to take it apart and see what's inside though.
