When do projector bulbs need to be replaced
|
|
Usually, to judge whether the projector bulb is aging, we will judge from the following three angles.
Projector bulbs
The projector lamp should be replaced when:
1. The projected image starts to turn black or begins to deteriorate.
2. The error indicator on the top of the projector flashes red at a frequency of once a second.
3. When the projector continues to use to the lamp life time, the "LAMP REPLACE" message will be displayed on the screen. Check the "About" menu, the lamp usage hours will be displayed.
The above is an example of an Epson projector.There are slight differences between different brand identification methods, which are not listed here.
Some cheaper or older projector products may not have "human tips",We can directly observe the picture projected by it,when the color of the picture projected by the projector obviously turns yellow and dim, it proves that the projector should be replaced.

When you start complaining about the dark projection screen and the unbearable bad brightness, , you can buy a new projector lamp.  |
