- 1). Unplug the TV and wait several minutes. There may be some residual charge inside the TV, you should let it rest and discharge.
- 2). Loosen the screws holding the cover onto the back of the TV with a screwdriver. You will know all of the screws are out when you can just pull the cover away from the TV.
- 3). Look inside the back of the screen and towards the bottom. Locate the 3 bulbs; they are blue, red, and green and positioned near the bottom of the screen.
- 4). Wipe away any dust or dirt from the bulbs using a lens cleaning spray and a soft cloth. Be gentle when working so you don't dislodge or damage any of the parts of the TV.
- 5). Replace the cover of the TV back into its place and tighten the screws.
