LCD monitor display not working

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 it be the inverter, lamps or back light? thank you very much.

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.

A friends laptop is only showing a white screen


Step 1:
Fix a White Screen on an LCD Monitor

b>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 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.
b> b> b> Without this test you'll have to guess because as I mentioned before this could either bad motherboard or bad LCD screen.

You'll have to disconnect the video cable from the LCD screen (connector 2) and the inverter board (connectors 3 and 1). After that you connect another working screen and test video. For this purpose I'm using one of my test LCD screens. My test screen is cracked and because of that you see a wide white band in the center but it still works fine for this test.

The original screen is white but my test screen works normal (except the crack of course) and I can see the image. After this test I can tell that the problem must be related to the screen. After I assembled everything back together and connected the original LCD, it's still white. CONCLUSION. In my case this problem is related to the LCD screen and it has to be replaced. b> b>

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.

Hello,

Unless you're hooking a computer up to the monitor and watching TV/DVDs on the computer, you need a TV box such as this: http://www.kworld.com.tw/product_overview.aspx?P_ID=15 in order to watch TV/DVDs on your monitor.

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.
