Ktoll, Wow you will need to do a lot of surfing and a ton of reading to educate yourself as to why your monitor has the BLACK SCREEN OF DEATH!! Yes, you too, with some research might possibly fix your own monitor if you know how to use a soldering iron. Or you may want to contract out the work to a monitor repair shop! But let me suggest that you find out the reason so many monitors of all brands are failing. Have you found out how to evaluate the state of the monitors "switch-mode-power-supply"? Here's what's going to happen to your monitor. The guy at the store is going to take your display in trade. You walk out with new wide screen lcd. But the store Technician will "crack open" your monitor and with a little luck remove a few "electrolytic filter capacitors" and install new ones, button the unit up and take it home or sell it for $40-$60. Well, when strange things start happening to LCD displays with "cold-cahtode-fluorescent-lamps" that only light -up for 1-2 seconds the very first place I would look is the SMPS. Read some of my other responses to get a better handle on "BSoD" problem. You may also want to visit youtube and watch a video of a LCD monitor being repaired for the same symptom as you're having. also visit FYI www.ccl-la.com/badcaps.htm , www.lcdparts.net

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

How to shutoff ipod a1236


Turn off your iPod by holding down the "Play/Pause" button for two or three seconds. The screen should go blank, and your iPod will remain off until you turn it back on again by holding down the "Play/Pause" button.2 Let your iPod go to sleep. When an iPod isn't used for two or three minutes, it automatically goes into "sleep" mode. The screen will go black until you touch any of the controls. Sleep mode uses considerably less battery power.

    Dell monitor flashing green power button black screen.


    Your computer is in sleep mode, a low power mode that conserves power by turning off the screen and hard drive.

    Push the power button on the system and the computer will resume.

    If you don't like this feature, you can turn off sleep mode in the power options in Control Panel

    My dell dimension has gone to sleep mode by it self, and now it does not go on?? tried to take out the power cord and start but straight away it goes to sleep mode??

    When the system is going back into sleep mode what color is the power button flashing. It should like the system my not be going into sleep mode but have a more serious problem.

    Also let me know what you see on the screen as you turn on the system.

    Another thing to try is after you unplug the system hold down the power button for 30 to 45 seconds. This will reset the power state of the system. Note if you have the system plugged into a power strip you will want to reset the power strip too.

    Screen goes black. Put it in sleep mode. Then hit the start and it comes back on even with powercord in..what can fix it?


    this could be probably due to static charges or corrupt bios settings.
    Turn off the PC, disconnect the AC Adapter and remove the battery. Now press and hold the power button for 45 seconds.
    Now download and install the latest BIOS update available for your notebook from manufacturer's website. If issue persists, reinstall the display drivers.
    I hope this will help to resolve the issue.

    My screen is black. I think I may have put it in


    depending on how the system is set up simply pressing the power button on keyboard or the PC
    If you get no response no matter what you try then unplug the PC from the mains for 10 seconds. I have had this once where the ram went faulty and the system ended up needing new RAM but I think this is extremely rare especially in your case.

    Sharp light turns green thern turns yellow screen goes black


    it is going into sleep mode, good luck with this.... i am currently asking how to get my hard drive to quite putting my monitor into sleep mode.

    although it hasn't worked for me because my screen stays black, one of the options given to me is to try to start in safe mode and then adjust your settings to "never" on the energy/sleep/hibernate mode

    some one else suggested that i remove and reseat the video card

    hopefully one of those will work for you

    Phone won't ring in sleep mode


    I had the same problem with my iPhone the only way I was able to fix it was to re-flashed the latest 2.2 firmware. Power phone off, power on by holding power and home at same time, hold power for ten seconds and then release still holding home key for another 30 seconds to put phone in DFU mode. Then plug into iTunes it will detect phone in recovery mode and allow you to re-image

    OK I have the same monitor, I was given it by a client when I couldnt fix it, I DO have the 19V supply and still getting the same problem.

    If you open it and reseat all connections you can reach, I find it starts to work. Unfortunately after less than a few days use it goes off again.

    Hopefully this can help someone get further
