Introduction: DIY LCD PROJECTOR
Here are step by step instructions to make your own lcd projector without spending major $$$
I did this a while back and I'm just now getting around to posting it.
Step 1: GET a 14" or 15" LCD MONITOR
I used a fifteen inch and the sides run outside of the border sooo try and get a 14 instead. A few different brand monitors are usable for this project , and a few aren't.
Here i am using a CMV 522a. These work great because they don't have the ffc
(flat flexible cable) issue that some monitors do have.The problem on some is that there is a cable connecting two circuit boards behind the lcd screen, and you need that cable to be long enough to move the boards out of the way of the lcd screen.
here is a list telling you what monitors have/don't have this issue
Step 2: DISASSEMBLING THE MONITOR
Here I had one screw in each corner. I had to pull 2 covers off of the sides of the "neck" to uncover 4 more screws. UNSCREW ALL OF THESE!
Step 3: Be Careful
With all of the screws taken out ,the back of the monitor should just come off. I had to take a flat head screw driver and run it along the seams to pop it off..
BE CAREFUL!! SOME MONITORS HAVE PARTS THAT MIGHT BE CONNECTED TO THE BACK OF THE MONITOR COVER!! DONT JUST RIP IT APART LIKE A WILD BABOON!!
Heres what I'm looking at with the back off...
Step 4: Unscrew Circuit Board and Covers....
Look for screws connecting the board and covers to the backlight ,because you are going to seperate the two since you'll be using the overhead projector lamp as the backlight.
Step 5: Unscrew Board and Flip It Out of the Way
unplug circuit board from backlight. unscrew and flip circuit board out of the way so you can take off the backlight. i removed the power side of the board for a bit cos it was easier to flip without it.
Step 6: Separate Backlight From Lcd Screen
the backlight is attached by clamps around the edges so gently pry/bend them off with a flathead. gently remove lcd screen from the backlight casing. throw away backlight. The LCD backlights contain hazardous material Hg as a fluorescent lights do. So dispose it properly.
Step 7: Set It Up
reattach the power board to the board connected to the screen and plop it on a projector this monitor only has vga input so if you have component cables you will need a convertor box. they make convertor boxes that convert component cables (and others) to vga. i put a fan on the screen because the screen does get hot. i do it just in case.
plug in a game or whatevar and have fun. this thing is not hd or anything but good enough, and pretty fun to make.
We have a be nice policy.
