Ok, so I called Xbox tech support today because my 360 was acting crazy this morning..not wanting to read discs n such. Anyone who owns a DVD player knows that it's typically a dusty, dirty lens. Well, I wanted to ask them...did they recommend any type of lens cleaning device. They told me that lens cleaning devices risk damaging the internal hardware which will subsequently result in voiding your warranty. WTF??, how can you NOT clean a lens on a compact disk player??? That's like common practice!...How can you design a $400 system, which I am happy with and I am not complaining abt...but..nontheless....How can you design a system that has a CD LENS that CANNOT BE CLEANED. They were like.."we're sorry sir, all you can do is clean the disc tray"..yea, LIKE THAT IS GOING TO HELP! So I said...you know what...I am going to treat this thing like my home PC. I hooked up my vacuum cleaner...I put one of those attachments on...and I ran it over every vent that the thing has.....I've had no problems since. Dust is some crap. I'll go to walmart one day to buy a dust cover though. I thought I'd share this...but I recommend dusting the thing out with ur vacuum cleaner at least once a mth. If ur not playing ur 360...cover it up with a computer cloth or a towel or something. Xbox Tech support sucks!
