LCD monitor display not working

My screen turns on fine but it is very dark to see anything on the screen. If you are an inch away from the screen you can vaguely see the image set on the desktop. Can you please help me rectify the problem.

To correct this issue in Acer LCD's you will need to have a series of capacitors replaced. If you understand electronics then it's not hard to find and replace the bad ones. Though I do advise to replace the lot since your already in there.

If you don't have a good understanding, then get your local TV tech to take care of it. The parts are cheap, it's the labour that will cost you the highest part of the bill.

Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

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.

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.

Regards

When it's turned on, the light on my monitor blinks but the screen doesn't display anything. Why might this be happening, and how can I fix it? Sampo LCD PD-80A monitor screen blinks on and off every 4...


I just replaced the relay on my second-hand NEC2010X . It would go out after some period of time, but come back if I unplugged it and then plugged it in again. It finally died altogether, but when I replaced the relay, it worked fine. Apparently this relay is the weak link on many LCD's (probably the only moving part in the whole thing). So open it up, unsolder the relay, and put in a new one.

HD19A / 19-Inch light flickers but no display


One of 2 possibilities come to mind. 

 

1,  The vga chord is loose on the back of the monitor.

2, Your resolution is set too high or low to be displayed.

 

The blinking light means that the monitor is either not getting or understanding a signal.

 

Hope this helps.
