Step 1: Get an old crt monitor.
2. Go to a nearby recycling center and take one home: crt monitors are very easy to find in recycling centers because they are sooooo bad.(crt monitors are generally about 3x lighter than lcd monitors, so carrying one home shouldn't be a problem(I walked 5 miles home with a 30" crt monitor, so you can too))
3.Find one inside an internal pata hard drive, these types of hard drives usually have 15"-22" crt monitors inside of them. you can find this type of hard drive inside a computer dating earlier than 1995 only.
4.Break apart the computer you are using to view this instructable to find a 55" !!!!WOW!!!! crt monitor
