Random Flashes on Macbook 13" native screen

My macbook screen has recently started flashing randomly, between brighter and less bright. It does so more when the display darkens after several minutes of inactivity and will sometimes stop when I touch the trackpad, only to begin again after the display darkens again.

You could try reseting the pram. this is accomplished by holding down Command, Option, P, and R at startup you will want to hear the start up tones at least three times. if that doesnt work you might have an inverter issue, the inverter is located behind the screen and needs to be looked at by a pro

Why is my Bose radio is too dim?


The Bose Wave Radio has two brightness levels: Bright Hi (with a range of 8-15, and default of 10) and Bright Lo (1-8, default 4). The radio automatically goes from Hi to Lo when a room is darkened so the display doesn't interfere with sleep.
On recent models you can reset the defaults to make the display brighter or dimmer in both Hi and Lo levels.
1. Press and hold the Alarm Setup (Menu) button on your remote until -setup menu- appears in the display.
2. Then press the Tune/MP3 button until Bright Hi- appears. Use the Time - or Time + buttons to change the settings.
3. Go to Bright Lo- and adjust that setting too if necessary.
4. Press Alarm Setup (Menu) again to exit setup, or simply wait 10 seconds.
You're done! Note that if you set both Hi and Lo to 8, the brightness will stay the same all day and night.

How do I adjust brightness and contrast


On a MacBook try hitting F1 and F2. You'll notice they have small little icons to signify less bring and more bright.
Also doable via the display Preferences (Apple Icon top left, Preferences, Display).

Display not bright enough on Bose AWR1-1W clock radio


Yes...within a range. The display will automatically lighten and darken depending on the amount of light in the room. During the day or when there are bright lights in the room, the display will go to full brightness. When the lights go off or the room is otherwise darkened, the display will shift down to a lower brightness. You can make the "lower brightness" a bit brighter by holding down the CLOCK SET button and pressing the 'volume up' button.

Ipod touch 1st generation display very dark


You probably reduced the brightness one time, but you just forgot about it. To make the display brighter, do this:

>on your iPod touch screen, go to Settings.
>once the Settings window is open, you'll see Brightness from the list, tap on it.
>now, you drag the button to make the display darker or brighter. drag it to the left to make it darker, to the right to make it brighter. You'll notice the display darkens / brightens simultaneously as you drag the button.

MacBook 13" starts but screen is barely visible. Tried System Preferences - already on brightest setting. Works fine otherwise. Any ideas? Capt. Dave


could be your inverter board, whitch controls the backlight. I could very well be the backlight as well, but that is less likely. Inverter boards are not all too expensive, and if you are knoledgable with laptops, i would say doit yourself, but if you have any doubts, take it to apple, sur it will cost more, but it is the safet bet.
