Well just to let people know if the DVD drive is broken i.e laser is foobared then its no point in buying a new drive apparently the DVD drive and mother boards are linked via software and codes. The only solution to this was buying a new laser hop!
Cost £7.00 of egay one hour of my labour taking apart, cleaning, de-solidering static point, re-greasing and some superglue on crappy cheap screws on plastic it works perfect now and its got an HDMI port on this one too!
