A computer monitor has a front-mounted LED that displays its current status and flashes in the event of an error. When an error occurs, the flashing may be accompanied by an error message on the screen. If the screen does not display an error message, the problem most likely falls into one of four common categories.

Unsupported Display Mode A video card has the ability to send output to the monitor at many display resolutions and refresh rates. However, no single monitor is capable of supporting every possible display mode. When the video card sends an unsupported display mode to the monitor, the monitor shuts off to prevent damage and blinks, or displays an error message. Standby Mode b> When a monitor detects no video signal from the computer, it assumes that you have turned the computer off and enters standby mode to reduce power consumption. Dell and HP monitors display an amber light when in standby mode. The status light on an Apple monitor blinks slowly. Incorrect Power Supply Some monitors such as certain Apple Cinema and Studio displays use external power adapters. Because different power adapters may have similar connectors, these monitors are designed to detect when an incorrect power supply is connected and blink the status LED rather than attempting to turn on. In the case of an Apple display, the LED blinks in an alternating short and long pattern. b> Backlight Failure b> A flat panel LCD display has an LED or fluorescent backlight that illuminates the pixels and makes it possible to see the contents of the screen. If the backlight fails and requires replacement, the monitor is unable to display any information. In some cases, you may be able to resolve this issue by turning the monitor and computer off, disconnecting and reseating all cables. If the monitor still has a backlight issue, it requires professional service.

It sounds that the back-light inverter has the fault. If there is any winding short [cannot detected by measuring with an Ohmmeter], this type of fault can occur. The only thing to do is replace the back-light inverter board. The LED blinks indicates a short circuit .

In my dellvostro a860 , rite side of the screen colours are spreaded,it it looks like shade,,whats the problem in that i m not getting please help me..........


It is the screen Inverter, or the LCD screen itself.

Screen Inverter: A small circuit board located behind the Display Bezel, and mounted towards the bottom of the LCD screen,

http://support.dell.com/support/edocs/systems/vosA860/en/sm/display.htm#wp1183775

The yellowish long object, at the bottom, is the screen Inverter.

Here is another look at it,

http://www.batterycenturys.com/dell-vostro-a860-inverter-p-185294.html

Dell Support > Vostro a860 Notebook PC > Service Manual,

http://support.dell.com/support/edocs/systems/vosA860/en/sm/index.htm

In the list clicking on -> Display, will get you to the first link above.

Need guidance in replacing the screen Inverter, post in a Comment.

(Just a basic guide using a Vostro 1014/1015 Notebook PC. Not yours, but good for basic guidance. This is replacing the LCD screen,

http://www.insidemylaptop.com/replace-lcd-screen-dell-vostro-1015-1014-laptop/
)

[ Primer:
An LCD screen cannot produce light by itself,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

( Click on the small window with the monitor in it )

It needs an additional light source. A Backlight is the additional light source.
A Backlight can be a CCFL, (or more than one), or a series of LED's used as lights.

The Dell Vostro a860 Notebook PC uses one CCFL, for a Backlight, OR there are Vostro a860's that use LED lights.
(If you replace the LCD screen, make sure FIRST of what type of Backlighting it uses)

A CCFL is a Cold Cathode Fluorescent Lamp. Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

[Average thickness of a CCFL is 2mm. That is a little larger than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height ]

A screen Inverter is used to convert the power from the laptop, for the Backlight, and LCD screen.

Most of the time the fault is the screen Inverter.

The Vostro a860 Notebook PC's, that uses LED's as a Backlight, MAY also use a screen Inverter.

Primer over.

For your problem it could be the screen Inverter, but I lean more towards the LCD screen itself, is the problem.

How to test a screen Inverter? Requires a very sensitive multimeter.
Read; Expensive,

http://www.fonerbooks.com/test.htm

For a layman who does not have access to a sensitive multimeter, the method is to just replace the screen Inverter, and see if it is the problem.
'Parts changing', I know, but if you do not have the proper equipment to test with?

Screen Inverter replaced, and problem still persists, replace the LCD screen,

What does the blue blinking light at the very bottom, under the blue power button indicates?


According to the Dell 531 owners manual:

"Drive activity light-
blue light - A blinking blue light indicates the computer is reading data from or writing data to the SATA hard drive, CD, DVD or HDD."


http://support.dell.com/support/edocs/systems/inspd531/en/OM/appendix.htm

Safe to ignore. It will blink even when the computer appears to be idle.

My dell monitor turns on for 2 seconds then goes black and the green light blinks orange


I assume that you already try this monitor on another PC to verify that the problem is in the monitor, in this case you need to open it up and inspect the fuse, transitors, solder connections on the power/inverter board, see failed Dell monitors here for guide: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further.

I have a Dell flatscreen monitor that will not turn on. The power light blinks blue slowly


Hi...there,
It's seems you got a busted backlight inverter. If you still under warranty send it back to Dell for repaired. Happy Holidays!

Dell E172FP 17 monitor keeps blinking


That sounds like the backlight inverter board. Check ebay for the board or a repair kit for it.
