Stuck in sleep mode w/black screen

My Samsung is a little over a year old (warranty OVER!) and it's gone into sleep mode (power button flashing nonstop and will not turn off manually.)  It's definitely not my mac, and I've disconnected both cables for some time and tried that again, nothing. Any ideas?  Thanks!

    Compaq FS740 stuck in sleep mode please help

    My gateway FPD1975W 19 inch is doing about the same. It turns itself on and off constantly with wide white bands flashing on the screen. If you disconnect it from the computer, there is nothing. When hooked up to computer, you cannot turn it off. This is Dec and the warranty expired in Sept. Tried a different monitor on the same computer and it worked fie. Great timing!

I know this is after the fact but may help save time in future. The problem is normally one of two problems: either the internal IC chip has failed (most common) or the start capacitor in the built in power supplied has failed (a power surge will cause these). Either problem is for all intents and purposes a non-fixable situation. I know this doesn't fix it but may save you time and aggravtion.

I've been to this page several times looking for an answer. The strange thing is is that the first time this happened to me I must've read a post wrong and held down the power button and the menu button and the monitor woke up. I had to do it several times after that and it worked every time. But now nothing seems to help.

    I've done all that, it seems that it is the monitor itself. Nothing to do with the video card. It is the monitor alone that is not responding.



I have same problem, the monitor is stuck in sleep mode. L70N HYUNDAI. how, exactly, do I get it out of sleep?

If possible, try a friends monitor first. If it works, you can then change the sleep mode setting so that it won't come on again. If the other monitor does not work, the video card is probably defective.

Screen went black but computer still

Sometime this will happen when the Dell machine is stuck in sleep mode. Press and hold to power button for about 10 seconds. You should see the fan spin just a little this tells you that sleep mode is off. now try starting the computer like normal.

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

Why does my HP vs17 monitor screen keep going to blank black screen like it turned off but did' power button light is still on? Everything is running but no picture.....keeps happening everytime...

this old monitor has 2 issues.
1: it has CCFL tubes that love to burn out (backlamps)
most this old are long go, yell,dim.,blinking or DEAD.
2: push the menu button on front of mon. turn off power saver.

3: if the PC goes to sleep, or hibernete mode (parked)
then that is 100% normal
if you dont like feature then go to windows control panel
click power, ICON and turn off all monitor sleep /hibernate modes.

that assumes windows, no OS stated.

if the lamps are dead,
use flash light pointed to sceen, see data. ? bingo for bad CCFT tubes.

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.

A flashing power light like that indicated a blown power supply. Your monitor should be under warranty with Samsung. Check the mfg date on the back sticker, if it is less than 3 years then contact Samsung. If it is out of warranty then contact us at and we can get you the info you need to do the repair yourself.

Black Screen and takes blank pictures

It sounds like a stuck shutter. As the camera is less than a year old, Nikon should fix this for you for free under warranty. Contact them.

For others that experience this with cameras that are out of warranty:

A stuck shutter is another common failure mode for digital cameras. The symptoms of a stuck or "sticky" shutter are very similar to CCD image sensor failure. The camera may take black pictures (for shutter stuck closed), or the pictures may be very bright and overexposed, especially when taken outdoors (for shutter stuck open).

To confirm a stuck shutter, put the camera in any mode other than "Auto", and turn the flash OFF (you don't want to blind yourself for the next step). Next look down the lens and take a picture. You should see a tiny flicker in the center of the lens as the shutter opens and closes. If no movement is seen, then you likely have a stuck shutter. If so, please see the following for further info and a simple fix that may help:

No Display on my Samsung 204B monitor

If you know how to open it up and get to the power supply you will find three capacitors 2-820uf and 1-330 @ 25vdc 105o.they will have puffed up tops replace them. FYI the monitor has a 3 year warranty.

Flashing power indicator

Sounds like a power supply problem unless there is a short in the deflection circuits causing the power light to flash. I'm afraid it'll take a technican to figure out what is wrong. If it's more than 7 years old, you might consider replacing it.
