]]> 87070 2 0 Step Find the right LCD Many LCD screens have flat, flexible cables –known as FFCs – that are too short to use for this project. An easy way to find a screen with a long enough FFC cable is to search “LCD brand + model + FFC issue” online.

]]> 87071 3 0 Step Remove monitor stand and casing Make sure the monitor is disconnected from any computer or power source and wait five minutes before you start. Lay the monitor facedown on a towel or blanket. With a Phillips-head screwdriver, remove the stand and back casing.

]]> 87072 4 0 Tip Ground yourself and avoid static damage to the inside of your monitor by wearing an antistatic wrist strap.

]]> 87073 5 0 Step Disconnect cords Before disconnecting any wires, take a photo of your monitor’s guts for reference when reassembling. Then, carefully disconnect all power and data cords, removing tape, if needed. Then unscrew and remove the monitor’s inverter board and any other circuit boards.

]]> 87074 6 0 Step Remove LCD screen Unscrew and remove the plastic and acrylic frames protecting the back of your LCD screen. Carefully lift the fragile glass out of its casing and lay it on the towel or blanket. Use caution with the circuit board attached to the base of the screen and wiring connected on the sides – damage to these could kill your LCD for good.

]]> 87075 7 0 Step Secure foam strips On the top face of your overhead projector place two Styrofoam strips – about a half inch thick – on both sides. Secure them in place with gaffer tape.

]]> 87076 8 0 Step Set LCD on projector Place the LCD screen facedown on top of the foam strips. The strips will protect the delicate screen from the intense light-bulb heat.

]]> 87077 9 0 Step Mount circuit boards Reconnect the inverter board to the LCD screen. Use the photos you took earlier for reference.

]]> 87078 10 0 Step Reconnect cables Reconnect the power and data cables to the screen’s inverter board. Then attach the LCD controller cable – the one that normally connects a computer to a monitor – to the computer tower containing the media you want to project.

]]> 87079 11 0 Tip To connect your monitor to a game console or cable box, you’ll need one that comes with a standard S-Video or composite input connection or a VGA box converter.

]]> 87080 12 0 Step Mount fan Using gaffer tape, mount a small electrical fan – like the one found inside a computer – to the side of your projector. Direct the airflow into the space between the projector and screen. Without constant cooling, the heat from the overhead projector will create a brown spot on your LCD screen, eventually burning it out.

]]> 87081 13 0 Tip If you don’t have a small fan, a raised box fan or desk fan positioned to the side of your projector also works.

]]> 87082 14 0 Step Find screen Choose a space you’d like to project your moving images onto. A white wall, white board, or custom screen are all effective, or you can paint a wall with paint designed for video projection.

]]> 87083 15 0 Tip For an image measuring eight feet diagonally, leave 12 feet of space between your projector and screen.

]]> 87084 16 0 Step Fire up your new projector Turn on your computer, overhead projector, cooling fan and dim the lights. You’re ready to start projecting movies, web videos, and games!

]]> 87085 17 0 Fact On April 23, 1896 the very first movies were projected for American audiences on one of Thomas Edison’s later innovations, the Vitascope.
