Dell monitor blue light on no display


Hook it up to a different computer or laptop. If it still has issues then change out the cable. Add more info: has it ever worked? When was the last time it worked.

My monitor power light is on but no display it is under warrenty


Hi and welcome to the site,

Initially, consider an experiment. Shine a flashlight at an angle towards the screen with the monitor and computer both powered on. Note if a dark/ghostly image of the desktop could be seen. If yes, then it would be a backlighting issue. In most instances, it would be the inverter that provides high frequency, high voltage supply to the CCF (cold cathode florescent) lamps.

It is a hardware fault and not a setting nor a configuration issue.

Offhand, perhaps your best bet would then be to consult with and/or seek the services of an authorized Service Center (specially if still under some form of warranty).

Good luck and thank you for asking.

Assuming you are using Win-XP, go into control panel, Appearance and Themes and Choose a screensaver. There should be an option below the screensaver choice to adjust Power Saver settings.

Dell 17" Monitor - Won't display anything, power light flashes


Akeru, It may or may not show up again. My guess is that it will. This seems like a power supply/inverter/CCF tube issue. The lamps try to fire up but due to a possible fault in the Switch-Mode-Power-Supply and or the Inverter circuit the SMPS goes into shutdown and does a self reset after 5 seconds. And then repeats the whole cycle again. Well if the unit is over 5years old you can do several things. 1. See if DELL can do a swapout. Send your's+$40-$90 to them. They send you a same model REFURBISHED (new CCF tubes/inverter/smps) and a short 30day min warranty. 2. You can locate a electronics repair shop ( TV/VCR/DVD/Monitor) that knows all about cold cathode fluorescent tubes and their power source, Inverter type. 3. Try to effect repair on your own. That's about all the options that a consumer/user has open to them. I'm louie12fix on fixya or lmistyrel@ aim.com Bye for now.

Blank LCD screen


Hi,

The description "comes on very faint" is indicative that the backlight is not turning on. The backlight as the name implies provide the illumination of the rear panel of the LCD display. It is made on 1 or more CCF Lamps (cold cathode florescent lamps) and are powered by an inverter that provides the high frequency high voltage needed for the CCF lamps to work. Since the entire screen is dark and it is highly unlikely that both or all the lamps would go out at the same time, it would highly be likely that the inverter is the culprit being the common denominator to all the lamps.

Should you venture to perform a DIY (do-it-yourself) (with the necessary precautions and safety in mind), look for a board that would have small transformers and have connectors that leads to the CCFLs. They often go bad because of dried up/blistered capacitors, cold solder or a general failure in the electronics.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

LCD monitor display is not appearing


Hi,

It would seem that you are on the right track. If the desktop could be seen (albeit very dark background) then it could either be the CCF Lamps (cold cathode florescent) or the inverter that powers the lamps. One way to verify is to shine a flashlight at an oblique angle to the screen, semblance of part of the desktop could be seen.

Often, the larger the screen, the more the number of CCF lamps. Being a 17incher, I wouldn't be surprised if your Acer AL1714 would have two. Having said that and I am assuming that both lamps are not working, then the common denominator would be the inverter. It is relatively easy to replace the inverted. It is sometimes more difficult and challenging cracking open the casing of the monitor than replacing the inverter. Additionally, inverters are readily available online. It is also not surprising that inverters for other brands/models would also be used in your Acer.

This would be a good place to start for inverter boards. This is a nice tutorial if you are considering a DIY.

Hope this be of additional help/idea to Coolguy's assistance. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Screen going off after 4 seconds


Hi,

This is a typical LCD monitor problem. Here's a copy of my response to a similar issue /  post.

...If the power light stays on and the unit works even if for just a moment, then chances are that you either have a cold solder, or a heat problem with some components or your CCF Lamp is starting to fail.

All possibilities require that you open your LCD monitor and perform diagnostics of the components/circuitry inside. This of course would require that you be familiar with components, circuitry, soldering and the use of a VOM.

Cold solder - refers to soldered connections that have lost 100% of their connectivity. When the unit is jarred or after some time of use it looses completely its connection. The corrective measure require that the said cold solder be located and resoldered.

Heat problems with some components - the most often are power capacitors. These are can types rated something like 470uF/16V.  When power is applied and heat starts to build up, they start to looses their capacitance and therefore can no longer hold a charge.  Most cases, there are physical evidences such as blistering, brownish leakage at the top or at the bottom, swelling or gaps at the X/Y indentation at the top.

CCF Lamp - may involve the backlight or the inverter that powers it. A way to verify this is to shine a flashlight on the instance the screen blinks out at the screen. A faint image of your desktop should be visible.  The CCF Lamp is similar to household fluorescent lamp which of course can fail after some time of usage.  The inverter is a high frequency high voltage power for the lamp.

Since there are dangerous high voltages inside, extreme care should be practiced when working on exposed components.  Should you not be comfortable doing this, perhaps your best bet would be to seek the services of a qualified technician.

Hope this be of some help/idea. Pls post back how things are or should you need additional information.

Good luck and kind regards.
