Question about Acer AL1711 17" LCD Monitor

1 Answer

Acer al1711 shows only a white screen

I searched for this problem on FixYa and I only found troubles with the backlight or the inverter causing a dark screen showing a faint display. My problem is completely different.

I have a al1711 which shows a totally white screen. The monitor reacts on the energy saver and turns off when Windows tells it to do so.

When I press on the "auto" button on the front of the screen, no display is showing "Auto confi please wait". Pressing the menu also doesn't give any result.

I hope you can give me a solution to save this monitor.

    I'm having the exact same problem with the exact same screen. Brand new. Have completely pulled it apart but can't find anything out of the ordinary. I was looking for dry solder spots but found none. Not sure where to go from here.

These are pretty old now but I'll respond anyhow-
When there is absolutely no screen content and white, it means that ALL pixels are turned off; black, means all are turned on. If you have a white screen, it means that a component in the video stream has failed; a black screen (preferable failure!) often means that the backlight lamp or its inverter have failed. The latter is a potential DIY fix, a dead IC in the video path normally not since most of the signal chips (ICs) are placed and soldered by robots and the pin spacing on those is pretty much beyond the capabilites of an untrained hand.
The only exception I can think of is if the ICs no longer have voltage supplied to them from the main power supply but you would need at least a cheap multimeter to locate that.

Why my tv have dark screen


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.
Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.

Acer AL1711 17" LCD Monitor showing white screen


Hello,

A white screen indicates the power supply board is not putting out the correct voltages to properly power the monitor, just the back light. This type of issue is caused by a failure of the filter capacitors on the power board. You can rebuild your power supply board and bring the monitor back to life by just replacing the the bad capacitors. The problem is that model the Acer AL1711 could come with 1 of 4 different power supply boards install depending and the date manufacturer and supply on hand. If you want to repair the monitor if you could open the unit and get either the model number of the power supply board or send a picture of the board to me I will be glad to help you repair the unit and get it back up and running. You can contact me to send the information at tech@ccl-la.com

Acer AL1711 monitor it almost too dark to read. have tried to adjust brightness etc. nothing seems to work. any help would be great. thanks


You probably have a back light problem. This is caused by a faulty inverter board or a faulty CCFL lamp.

When you repalce the caps, they should be repalced in a set since bad caps can look normal but can have high ESR.

And yes, you can have bad lamp assembly:

My acer laptop screen is dark


Hello,

If your laptop screen is dark, it could be the backlight,inverter, or bad lcd. You can test the backlight by starting the laptop and give it a few seconds to load and take the laptop in a dark room and shine a flashlight on the lcd and see if you can see any pictures or icons. If you can, you may just need an inverter to correct the issue, If not, you may need to replace the inverter and lcd both.

If you find that you need parts to correct the issue. I would suggest that you begin with replacing the inverter first, as they are usually less expensive.

If you can supply me with the model number of the specific laptop you are having trouble with and I can try to locate more information on replacing the parts.

Thanks

ACER ASPIRE LCD TROUBLE!!


If the screen appears dark with only a faint image or picture and the brightness can't be adjusted then it is likely that the screen backlight is not on - the backlight is like a very thin flourescent tube that runs along the bottom of the screen and provides the illumination. The backlight tube may be faulty or the small electronic inverter unit that powers the backlight tube may have failed. Occasionally the backlight is off because the little switch that is used to detect the screen lid being closed is broken or stuck in. If your backlight is faulty, some engineers will replace it - but it is more common that the entire screen is changed. If it is the inverter they can usually be replaced from ebay.

Carefully open the screen lid and look at the back of the screen there is a type number [like LTN15ox3] you can then obtain a replacement screen from ebay searching for this type number.
However if the screen only shows a faint dark image the fault could be the screen inverter that powers up the backlight tube in the screen.
