How to replace an hp 070 projector lamp

undo the top cover you will see a black cover with clips and at the back or side there are two small screws which hold the rear concave mirror in place undo the screws bend the clip back gently and remove ....pop out old bulb and put in new bulb with a piece of tissue dont touch it with your fingers.... do all the rest in reverse order ...did mine tonight took 10 minutes just a bit tricky getting screws back in.....you need a long magnetic posidrive with a small head....
