For my phone, I take the battery out, then try again, until it turns on properly.
The forerunner to the touch screen was the light pen. A light pen would be used to select buttons or check boxes on a standard CRT.
iPods and other devices use a backlight, a luminescent underlay beneath the translucent screen. The screen itself doesn't completely block the light out, even if the screen is displaying a black image.
Yes, it is.
Black is considered as the `absence of light', or the complete absorption of the visible spectrum, from which no light reflects. In video projectors, the light is completely blocked from reaching the screen, creating the same effect. It appears to be black because you're usually watching it in a darkened room and in relation to the brighter areas on the screen, your mind perceives it as being black. In reality, if you were to look at the screen, you'd still see that there's no light hitting it to reflect back to your ryrs from the screen.
If the screen is actually white, it will absorb all light and appear black to your eye. If the screen appears white in normal light, all light will be reflected resulting in the combination of green and red (brown/yellow).
Lighted push buttons typically have tiny light bulbs or LEDs inside the buttons. My guess is that the problem is as simple as a few burned out tiny light bulbs.

black since the object is blue, it reflects only blue light thus, shining red and green lights on it will only cause the object to absorb the two colors and it will result to the appearance of the object as black
Push the set button and with the set light on, press either the scan or seek buttons to change the hours and minutes. GoodluckJoe
