My TV does not show anything when I press the power button. Why is it not working?
Common Problem.
What you may be experiencing is a problem with your lamp. The lamp is used to light the images that appear on your screen. If there is no light, namely no illumination from your lamp, the screen will be dark.
Like a light bulb, lamps burn out after a certain amount of use. Just like light bulbs, they can be replaced. The cost of these lamps vary by manufacturer and model. But, expect to pay around $300 or more.
Diagnosing Your Problem.
This may sound strange, but you may need to read the owners manual for your TV. It will (at least if the manual is any good) describe what each light, or series of lights, or light behavior mean for your set. This will help you determine if there is a problem, and help you to decide what to do next (or not to do).
For instance, a DLP HDTV may have two lights on the front panel. There is an ‘OFF’ light which is red. There is an ‘ON’ light that is green. After you turn the TV screen off, the green lights blinks. The owner’s manual tells you this means the fan is cooling the bulb. Do not turn the set on until the blinking green light is gone, if you want the bulb to cool down.
If both lights are on (red and green), with one of them blinking, the set may be re-setting itself. This may indicate a bad bulb or another problem.
What Is Happening In There?
The big drawback to DLPs are the lamps. While it makes for spectacular viewing, you have to understand that all bulbs have to be replaced. If you believe the bulb needs to be replaced, try this…
- Go to the main menu on your TV.
- Find the ‘picture’ quality option.
- Change your picture quality brighness or intensity to something less bright or vivid.
What you are trying to do is conserve bulb life by minimizing its use. Your projection bulb may last a while longer. This keeps it from running hot and wearing out faster.
