The projection lamp is gone and needs replacement. The lamp typically lasts about 8,000 hours on high end models and 1,000-2000 hours on cheaper models.LED technology based lamps lasts for about 20,000 hours. Operating the TV in a warm environment without enough ventilation or at high elevations reduces the lamp life. Setting the color or contrast to a lower level increases the lamp life.
Here's how to replace the lamp:
- Turn your TV off. Let it sit there for about 5 minutes to let the cooling fan help cool the lamp.
- Unplug
your TV from the power let it sit about another 30 minutes.
- Usually
the lamp has a cover that you will need to unscrew. Most manufactures
use a Philips head screw for holding the cover shut. Unscrew the lamp
cover.
- Unpack the replacement lamp. Be careful not to tough the glass, as oil from your fingers can damage the lamp's surface.
- Pull
the lamp out. Most lamps have a plastic tab or hoop on the handle that
you can use to pull it out. Follow the owners manual for specific
instructions on how to pull the lamp out. Make sure you do not touch
the surrounding lamp housing if you just turned off the TV. It can burn
you if it is hot.
- After the lamp has cooled, place it into the empty box of the replacement lamp. Never put the used lamp into a plastic bag.
- Using
the guiding post also called "gutters" by some manufactures slide the
lamp replacement lamp in pushing it until you hear a firm click.
- Screw the lamp cover back in.
