Question about Acer AL1714 17" LCD Monitor

1 Answer

LCD monitor display is not appearing

Hello hows it going.
Coolguy008 told me to seek you out for assistance. My question is in regards to my LCD monitor. I have the Acer AL1714 17" model. When i turn my monitor on the green light appears and everything boots up fine. once i am at the log in screen it is so dark, very dim to see anything but if i you were to look an inch away from the screen, you could vaguely see what is being displayed. The image is only a little bit noticeable in a right degree of light. I would like to know what could be the problem to a very dim screen. It works fine, but can the problem be the inverter, lamps or back light? In advance thank you very much.

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.

My pc desktop is showing a white screen when its on what should i do?


Is it an LCD monitor ?

When an LCD screen has turned completely white, there are three normal causes: the screen is defective, the video cable is not connected correctly, or the graphics card on the motherboard of the computer is faulty. You will need to troubleshoot these possibilities to determine which problem you have. If you are not experienced in working on computer equipment, you should not attempt to disassemble your LCD screen because you could easily damage it. Seek professional assistance unless you have experience working on computer hardware.

Disconnect the white LCD screen from the computer by unscrewing the blue monitor cable. Connect the working LCD screen to your computer by attaching its blue monitor cable to the same slot. If your computer display does not show on the functioning LCD screen, try rebooting your computer. If it still does not display, the problem is with your computer's graphic card on the motherboard. Seek professional repair assistance. If your computer display shows normally on the working LCD screen, proceed to Step 2. Unplug the LCD monitor with the white screen. Disassemble the rear panel of the monitor with the small screwdriver. Carefully separate the screws into piles so that you can keep track of how to reassemble the monitor. Locate the internal video cable, a gray cable with a plug on the end that connects to the main components of the screen. See Below for the References section for photos of the video cable for assistance. http://www.laptoprepair101.com/laptop/2008/04/13/laptop-lcd-screen-turned-white/ Unplug the cable, checking for any debris or blockage. Reconnect the cable firmly. Reassemble the LCD screen. Plug it in and connect it to your computer. If the screen is still white, you have a defective LCD screen. You will need to replace it or take it to a professional repair service for assistance. Hope this helps.

Synchmaster 913 The unit displays 'Not Optimum Mode 1280 x 1024 60hz' after being run to approx 1 hour


Hello. That message appears when the video signal from the computer exceeds the monitor's ability to display it. If the sync is set too high(i.e. max sync on the monitor is 60 Hertz at that resolution), you will get that message. Check the video settings in control panel--("appearance and themes" in XP), go to the "advanced" tab and look at the refresh rate. Most computer video cards are able to far exceed a monitor's display ability. Don't exceed 60 Hertz--check the users guide for specs--the lower resolutions can have higher refresh rates(useful in games) Sometimes, a little lower video quality can yield a big performance difference in the display because the screen can update itself faster. (I use a radio control flight simulator pgm that is heavy on video ability).---Hope I was of assistance!---Rick

LCD monitor display not working


The problem you have is with the backlight lamp, which is not turning on. When this happens only because lamp is faulty, Acer LCDs have a security switch that will not turn the screen on at all and will return a blinking light on power on led , as diagnostic feedback.
If you have a dim light it sometimes means that the bulb is still ok, but is not working. This often happens because of a faulty capacitor on inverter, which is powering the lamp.
Although the above symptoms are typical of a faulty inverter, a faulty power supply, lamp, or A/D board can produce the same symptoms.
It's also possible that an inverter could have been damaged by a faulty lamp. If faulty lamp is not replaced before refitting the repaired inverter, in time, the inverter will fail again.

Best thing to do is taking your lcd to a local TV repair or computer repair that works with lcd (ensure they work proficiently on lcds , some of them doesn't), to test if it is the lamp or a faulty component on board. If possible find a shop giving you some warranty time, as, if there is more than one problem the LCD can fail again in few days.

Problem monitor


Hi, Sounds either a backlight problem (inverter or tube light) or the display interface. Since you have confirmed that it is your LCD monitor, your best bet perhaps is to seek the services of a qualified professional. Should you venture in doing it yourself (DIY), You need to open up the casing. A step by step procedure is better illustrated here . The working principles of notebook/laptop displays are nearly identical to your LCD. Hope this be of some help. Post back how things turned up or should you need further information. Good luck and kind regards.
