How do you change a DLP bulb?
Changing a digital light processing (DLP) bulb requires understanding of how the bulb is held in place and how to properly unhook the light. Generally, the bulb will be held in a cage by two black plastic wire clips.
To remove the bulb, you need to grasp both of these securely and twist them out. When putting the new bulb in place, you’ll need to make sure that the two wire clips hold the bulb tightly in place. Once the new bulb is secure, you can reattach the viewing screen or housing in place.
If the screen or housing is held in place by screws, ensure you do them up tight against the viewer body before replacing the back cover. Once the cover is on, you may need to re-align the image using the service menu settings on your projector.
This menu is sometimes called the Service Menu without Technical Parameters. This menu will have settings for V-keystone, position, focus, zoom and others that you can use to re-align the image. Finally, you can power the device back up and perform a quick calibration test to ensure everything is working properly.
Is there a bulb in a flat screen TV?
No, a flat screen TV typically does not have a bulb. Flat screen (or “plasma”) televisions use a series of LCD, LED, or OLED pixels to display images, as opposed to a traditional display screen with a backlight behind it.

What is the plasma in plasma TVs?
Plasma TVs use plasma display panels to create images. A plasma display panel is a type of flat panel display that uses small cells filled with a mixture of inert gases such as neon and xenon, to create images.
When an electric current is applied, each cell illuminates in order to create a bright and vivid picture. Plasma displays have high brightness, have wide viewing angles, and have a very fast response time, making them ideal for displaying video and animation.
Plasma TVs typically have 3 cells that each contain a mix of the gases – one cell contains a mix of neon and xenon, one cell contains only neon, and the last cell contains only xenon. The gases are electrically charged and they change to a plasma state.
This plasma is then used to create images on the screen.
Can a bulb be replaced in a TV?
