Introduction: The Cheapest TV Backlight You Will Ever Find
Step 1: Get a Lamp
If you don't have one left over, IKEA has a perfect one for $5.99.
Step 2: Get a Light Bulb
I got a compact fluorescent bulb because the back of my TV was warm enough as it was.
Step 3: Combine!
If you run into difficulties during this step - find a four-year-old child to help you - or summon the spirit of Groucho Marx.
Step 4: Place It Behind the TV
Gently place the highly advanced contraption behind the TV.
Step 5: Turn On, Tune In, Pass Out
Or at least turn on and tune in.
