LCD monitor display is not appearing


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.

The problem may not be the monitor. Acer AL1714 is known for its weak power supply unit. Unplug power supply from monitor. If the green light on monitor comes on but goes out quickly, the power supply is the culprit!

Hello, I have to same problem. I returned my monitor to Acer but got it back unrepaired, they could not see the malfunction. But I kept on sending it back, until I got a new model. Now after 2 years I get the same thing with this monitor. But there's no warranty anymore, so I looked into the problem myself. I found out that inside the powercircuit board is connected to the mainboard through a 10pin connector. The 5 pins that are on the lowest row, show a trace of white powder, I suppose occidation. I sprayed a little of contactspray in it. I must say the problem is not gone, but much better. The problem shows not so frequent anymore and lasts not so long. At first the screen switched of for 3 to 5 minutes and came back on. Now the screen is gone for perhaps 1 second and returns. So I'm almost convinced the problem has something to do with the connection of the powercircuitboard inside and the mainboard inside, when the monitor heats up a bad connection occurs due to occidation of the 10 pin connector. If you find a solution that fixes the problem 100% let me know, please. Mario.
