Aluratek at107f , unit won't boot up
Had the same problem with mine the other day. Go outside in the sunlight or use a flashlight. Touch the menu hard key. you should hear it click. Using the bright light, click on settings, go to display, and turn up the brightness. I know this sounds elementary but for what ever reason, this device, when it goes into sleep mode, will adjust the brightness settings down. Hope this works for you.
