The bulb replacement is easy. Unplug (make sure the set has been off for a while), and open the bulb door in the left rear (one Philips screw). Loosen the two Philips screws on the bulb housing (they don't need to come all the way out), and gently slide the entire housing straight out. You probably want to clean that area out - I used a little shop vac and a very slightly damp rag. Insert the new bulb, tighten the screws and replace the door. While you have the shop vac there, clean out the two vents (one on either side).
Taking the screen off to clean the inside is a bigger project. There used to be a link in this thread with great pictures and instructions, but I think it is gone. IIRC, one of the most important things is to remove the speakers first and disconnect the wires. Otherwise, when you go to remove the screen, you won't be able to pull it away from the TV. Removing the screen is a two person job. Remove all the screws (there must have been about 20 - save the top of screen ones for last), and with a helper gently lift the screen assembly off the front. Have your helper hold the screen in place as you remove the last couple screws. Be careful not to flex it. Make sure you have cleared an area on your floor to lay it down flat. I put down a nice soft blanket. Wipe the inside and outside of the screen with a clean damp rag or lint free cloth. I wouldn't recommend trying to separate the layers of the screen. Someone here did that, and had a lot of trouble getting it back together.
Shop vac the inside of the cabinet with a nice soft brush. Ideally, empty your shop vac and put a clean filter on it first so you don't recycle dust back into the area. I even clamped some cheesecloth over the exhaust port. With the exception of the mirror and lens, don't use any cleaning products, just wipe everything you can reach with a slightly damp rag. Be gentle around the electronics.
Use a lint free cloth and alcohol based screen cleaner on the lens (I used Maxell Digital Screen Cleaner and an eyeglass cleaning cloth I bought at Walmart).
It is possible to remove the mirror, but I cleaned it in place. Use Windex and a lint free cloth. Spray the Windex on the cloth, not the mirror, and work a small section at a time. If the cloth gets dirty, use a fresh one. In order to really see the dirt, it helps to get down on the floor in front and shine a bright flashlight at the mirror. I was surprised how much I missed after the first pass.
Re-assemble by reversing the process. It does help to have a magnetized Philips screwdriver, as some of the screw openings are deep inside the frame holes, and it's hard to get them lined up.
It took about an hour and a half total, because I was being very careful.Could probably do it in a hour now that I know what I am doing. In fact, I really need to do it again soon, as it has been three years. I was watching the hockey game the other night, and I could see some dark smudges on the ice that are either on the mirror or the inside of the screen.
Edit: Just searched and found my original post on this - it's #6248 in this thread. Seems like I remembered most of the important stuff. Forgot that I removed the screen by myself!
