Mitsubishi 55'' rear projection 1080i hd tv lense cleaning

Pry off the lower speaker grill... Remove the screws at the lower edge of the screen framing and lift screen frame of the two catches at the top. Be careful, there will be wires still attached to the front button panel... Then lay the screen down and support the bottom of it in some way because the button panel wires won't reach all the way... then using windex and papertowel cleam the mirror and lens(s) on each of the crts. Also clean the back or inside of the screen area and reverse the process to re-mount the screen.
