I don't think its the problem of your monitor. Infact it could be the problem with your System RAM. Open the cabinet, took out the RAM, Clean it with a soft brush, remove the dust and re-insert the RAM. Hope your problem will be solved.

Thank you for using FixYa

I would try shutting down the computer in the normal way, and turning off the monitor.
Boot up and turn the monitor back on.
If it still doesn't work, then I would check the cables and power plugs and wall plugs.
Check the mouse and keyboard cable and any other cables plugged into the computer.
The next step requires a seperate monitor or laptop.
Try unplugging the monitor and pluging in another monitor. Most laptops have a common
VGA adaptor jack or even an Svideo jack.
If the other monitor does not work, Then take to a qualified technician for repair.
It could be your power supply in the computer or video controller.

I hope this was useful and please comment if this was helpful to you.

Connect an external monitor to your laptop. Start your laptop and use Fn+F5 buttons (or those appropiate to your model) to send the video signal out to the external monitor. If you do not get any image on the external monitor it means that most probably the mainboard is damaged (video card or even more). Expensive to fix or replace. Have it checked by a professional.

Well heres the story my sister made the screen fall on the floor one day (it fell on a very soft rug) every thing worked fine no problems but then a couple months later it started with this doesnt wana...


bamboboy, Stop yelling at your sister! ! ! If it worked fine after falling to the floor then there is something else wrong! First Prove that the pc works with a KNOWN GOOD monitor. Next, you may want to do the flashlight test with your BAD lcd monitor. Reconnect monitor to an already fully booted pc with the WIN-desktop screen showing. Then and only then turn on your LCD monitor and note what happens. If still black screen is what you see, then shine a bright light about 1" from screen and look very closely to see if the desktop is being displayed even though the screen appears BLACK. If the power supply is only partly bad you may see the desktop. I suspect that you have a power supply problem from your description. You should visit YOUTUBE and search for video clips of LCD monitor disassembly and typical repairs of units that have similar BLACK screen symptoms such as yours. You need to read more posts on fixya that I and others have made on other brands of LCD monitors that have same symptom. You will find plenty of them!! Get back to me after doing test and some more research. I'm louie12fix on fixya or lmistyrel on aol.com Bye for now.

Possible monitor or graphics card malfunction


The monitor is bad. The flashing is telling you that something inside the monitor has gone out. If it is still under warranty they should either fix your monitor or give you a replacement. Hope this helps & please remember to rate my answer.

Mag innovision LT716s monitor


When I turn on my computer the monitor takes a long time to warm up and colors change and vertical lines flash across the screen from right to left before the screen becomes normal again. Now the power light even goes out upon turning on my computer and I have to unplug the video cord and plug it back in to start the screen back up which even takes longer.

Dell m992 screen problems


If you notice, when you see the windows start screen, its usually "big and dopey". Thats because the video drivers aren't being used yet. If it is blanking out right after you see that screen (with the scrolling bar), my guess is it's a corrupt / bad video driver.

Was any other hardware added recently?

F-17 neovo monitor stopped working. power light is flashing yellow


The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1 The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours, sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occurr suddenly are a blown capacitor on power board, the inverter board powering up backlight lamp has blown, or a fault on main lcd controller board.
check also the video cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Check connectors, try moving the video cable, and if the cable is not built in, then also try a replacement cable.

Monitor suddenly goes black


Is this monitor and LCD flat Panel? If so this is due to a bad power supply, an inverter board going bad or LCD backlight bulb blown. When the backlight goes bad it gets just enough power to start up, but when it is on for a long period of time it goes black because the bulb is not stable enough to hold the charge because it is going bad. These bulbs can be changed, but they also can be costly!

Monitor (Dell 1701FP) flickers, flashes and goes black


Just to check - when the screen is black- can you see any image- in its un-illuminated state. To do this look sideways along the screen not straight at it. I suspect this is an inverter problem. Whether or not this is repairable I know not- depending on your local repair facilities Perhaps DELL can suggest a local agent.
