Help.. Xbox won't read anything in drive. Basically, if I switch off and switch on, I get the splash screen (green lights flashing on front) then it goes to the system info (skin) screen (screen with launch DVD etc) Clicking on launch DVD does nothing. Opening and closing the drive just makes the green lights on the front flash. I can hear drive activity but screen doesn't change to 'loading' If I use the CD player, keeps telling me that the disc is dirty or damaged on every CD I put in it. Got a feeling it's the laser as it's been playing up for a few weeks. Anyway, it's got a Samsung SDG-605F drive in it. What I want to know is where can I get a replacement laser from? I live in the UK. Have had a look on ebay but they only seem to sell them for the 605B and I've read on the internet that they are different (605F has a single pot whereas the 605B has two - or something like that) Can anyone confirm whether or not a 605B laser will fit in a 605F drive? Cheers.
