Can anyone instruct me how to remove the screen of a Tosh 42WH46 TV. I'm trying to get to my red, green and blue pots / guns and mirror as I can see they are thick with dust and I'm having a few minor image problems I think I can remedy. I've detached the screws at the rear of the set and am able to pull the top if the screen off at the top (see glance in which is how I saw the dust!) but it seems to be attached a bit more securely at the bottom. I've tried forcing it but it wont move, and I dont wanna break it off or indeed more importantly break the screen which is quite fragile. Any guideance would be appreciated as I wanna get those guns wiped and pray my small image imperfections disappear!
