cleaning inside projection tv

I want to clean the inside of my tv's mirrors and screen. My picture is getting very muted due to dust and such. I have tried to find the manual to do this but to no avail. I also want to know if I can use canned air to help blow out dust in it. Basically I need to find a step by step instruction so I don't manage to mess it all up. The tv is a 49in. Sony.   Thank-you in advance julieg290
