Dell backlight indicators

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.

HP Pavilion F1503 only displays a split second?

well, its a 2003 LDC 13 years old ,
its bad
the monitor itself of the power pack to it is bad.
you can test it on any PC< or laptop made
if its dead on all , then its dead.
what more needs saying,
older LCD monitors had old CCFL, lamps. that love to fail
newer are LED back lights that last for ever. it seems
so up grade?
seems your back light is dead
ever do the flash light trick

On my asus Eee Pc 1201HAB the display shifted to the left so the left side is partially cut off, how do i fix it?

1) Looking at the User Manual right now, and do not see a Hot Key on the Keyboard, that shifts the display.

[ Hot Key is also known as Special Key. The F1 through F12 keys at the top of the keyboard, and also for your model, colored keys on the keyboard ]

It could be the Screen Resolution is messed up. Not set at the correct settings.

Right-click on an empty area of your desktop screen.
At the bottom of the drop down list, click on Properties.

In the Display Properties window click on the Settings tab.

The screen pixel resolution should be set at 1366 X 768,

In the middle of the Display Properties window, you see the blue subheading - Screen resolution

Right under this small subheading is a Slider.
The Pointed 'arrow' with the green tip, and top, slides back, and forth on the 'line'.

It should state 1366 X 768.
If it does not;

A) Left-click on that green tipped Slider. Hold the left mouse button down. Move your mouse, and move the Slider. (Drag)
Move it to the Left to Decrease the screen resolution, or to the Right to Increase the screen resolution.

Can't set it to 1366 X 768? Post back in a Comment.
ALSO, the Color Quality should be set to -
Highest (32 bit)

If not click on the blue down arrow to the right of this box.
In the list left-click on Highest (32 bit)

Now go below to the right, and click on Apply.
After go below to the Left, and click on OK.

Still no joy?
Believe the problem is hardware related.

Could be something as simple (?) as a bad Video Cable.
(Goes from the motherboard, up under the left Hinge, and then up into the Display Assembly)

Could be the screen Inverter.

However the Eee PC 1201HAB is supposed to use an LCD panel, that has qa series of LED's for backlighting.
Newer backlighting that uses a series of LED's for the Backlight, doesn't require a screen Inverter.

There were some LED backlit LCD screen, that DID use a screen Inverter. Mostly the older models of laptops.
This is what makes me think your LCD screen's Backlight, (And LED), may use a screen Inverter,

Scroll down,
"5. Disconnect the power cable and video cable from the Asus EEE PC 1201HAB Lcd panel. The power cable connects the screen's power source, the lcd inverter, to the backlight lamp attached to a side of the panel."

Probably just a generic form, and didn't take in consideration that the Eee PC 1201HAB netbook, uses a series of LED's, as a Backlight.

May not have a screen Inverter.

To explain;

An LCD screen cannot produce light by itself,

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

It needs an additional light source. A Backlight is the additional light source.
A Backlight can be a CCFL, (Or two of them), or a series of LED's.

[ LED = Light Emitting Diode.
CCFL stands for Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

{Average thickness of a CCFL bulb is 2mm. That is a a little larger than 1/16th of an Inch.
The 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 LCD screen, and Backlight.

Do not see any listings for an Asus Eee PC 1201HAB netbook, for a screen Inverter. Believe the LCD screen uses LED's for a Backlight, and does NOT use a screen Inverter.

Which means if the problem is in the Display Assembly, the LCD screen itself will need to be replaced.
The LED backlighting is built-in.

[Hmmmm, I see a trend going on here that I do not care for, and just woke up to it. Have to replace the entire LCD screen, and cannot just replace the Backlight, or screen Inverter? Sounds like Ka-ching $$$$$ for somebody!

A screen Inverter usually averages from $20 to $40+.
A Backlight ( CCFL) usually ranges from $10 to $15.
An average LCD screen can range from $80 to $300+.]

How to know if the problem is in the Display Assembly?
Use a VGA monitor, and connect it to your laptop.

A) Laptop OFF, monitor OFF. Connect a VGA monitor's cable to the VGA port on the laptop.
(Left side rear. This is an example of a VGA Cable, and VGA connector { Port on a computer }, )

You can use an older CRT type of VGA monitor (Looks like a small TV), or a flat LCD screen monitor if it has a VGA cable attached.

B) Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.
By default the display should automatically show, on the external VGA monitor.
IF not;

There are at least three display options:
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external VGA monitor
3) External VGA monitor ONLY

Press the Fn key down, and hold it down. At the same time tap once on the F8 key.
The F8 key is the Display Toggle-Over key.
(Give it a few seconds. Sometimes it doesn't happen right away)

Still no?
Hold the Fn key down again, and tap once more on the F8 key.

Is the display off to one side on the external VGA monitor?

What's your problem?

First, make sure this isn't coming from your signal source; these items are not listed in any of the functions described in the manual for your monitor.
If disconnecting, changing or turning off your signal source doesn't get rid of the control item display, try resetting the monitor (maybe the display has some extra firmware features not in the documentation):
  1. Press the Menu button on the side of the monitor.
  2. From the On-Screen Display, navigate to the Setup&Reset menu using the arrow buttons, then press the Source/Select button.
  3. Navigate to "Reset" and select it.
This should restore everything to the factory default setting and get the TV/monitor out of whatever mode it's in.

Please help.. my monitor has no display and my don't even beep. the LED in the monitor turns back to orange after few seconds. cpu, disk drives and ram are working..

This is one of the serious problem that arises because if you set your monitor with a high resolution with high frequency, then the monitor doesn't display anything as it's frequency is out of the rang or limit of the monitor's actual resolution capacity. Each monitor will have a limit of max frequency that is said to be the Refresh rate (for each and every resolution setting the display is refreshed.) When high resolution is set with high frequency that is not supported by the monitor, it then display a message like "frequency out of range". If you press ESC key within the few seconds of this setting, it will revert back to its initial resolution. But if you continued with the setting of same High resolution with High frequency, the monitor is not going to display anything because its frequency is out of the range. Most of old monitors like CRT's etc doesn't support 1024×768 at a refresh rate greater than 60Hz.

My flatron L1710S flat screen will not come out of power saving mode. When I turn on the monitor the power button/light is green for a few seconds, the screen indicated "power saving mode", then...

I switch on my PC, ensuring that all cables, leads and power supplies are connected properly. The tower powers up no problems at all. I switch the screen on, the green led lights up, the screen is completely black. A blue box appears centrally on the screen with the text 'power saving mode'. The green led light turns amber and then the screen just goes black.

Please don't suggest going to control panel, as I can't get that far.

Monitor : no display and blue led light is blinking

The power supply is the first thing that the 110v electric line goes into. The invertor is the next item past the power supply, or sometimes contained within it. I do not thing monitors are a DIY repair.      First substitute a different monitor to confirm that it is, in deed , the monitor and not the video card.

Monitor Acer Problem

I agree it isn?t the monitor but I would suspect the video card you are connecting it to or the PC itself. Generally if a monitor doesn?t detect a video signal it will go into hibernation mode, typically displaying a no signal warning and changing the LED color from green to amber. When you start the computer is anything displaying at all? Are you sure the PC is powering up and booting?
