    I have the same monitor. The capacitor described in the solution does not look blown on my power board. n fact, nothing looks amiss on the entire powerboard. This monitor won't display anything. I can't even get the monitors menu to come up. When I plug it in, the green power light comes on but goes to yellow since I don't have it connected to a computer. I'm just trying to get the menu to come up. I don't even get the ACER LCD splash screen.

    Can someone tell me how you pop the back off the Acer AL1912.  


    I took out the four screws but nothing budges. Please advise.  Same problem, logo for a second, then the monitor shuts off; green light goes yellow 2 seconds after power on.

    I also have the same problem with my monitor. If I hold down the power button for a few seconds and let go my monitor comes back on.

The problem with this monitor is a leaking capacitor on the power supply board. It is the middle one at the top in a row of three. The value is 10V 1000uf. Common problem for these.
Remove 4 screws from back of display. The case can be popped apart with a small flat putty knife at different points along the two seams. Three latches on each side and two at top and bottom. Push and twist at the latch points. There is a metal cover over the two boards. Power supply board to left. Screws and plugs can be romved. Unsolder Capacitor and replace. Radio Shack probably has them. Maybe a couple bucks. Be sure the power has been off for a while. These also have problems with the button board and corrosion at ribbon cable.

I was asked by a friend of mine to look at his monitor AL 1912. Basically, inside is the power supply board that you can replace and you can get them online. That is the easiest way to fix the problem instead of looking for a component for your board. Mine, I believe, the problem is the rectifier ER1002FCT being shorted. I tried looking and found a site but they only sell in bulk, mainly dealing only with business owners.

I saw the board one time at ebay for $25.00 plus shipping of course and the seller is from Australia. Personally, I'd rather stick with the US sellers because I had a bad experience waiting for my item to arrive before because of US Custom. I know they are only doing their part.

I had a similar problem I had two of these monitors UK spec completely dead and on dissasembly there were two capacitors on the power board which had clearly blown - their 'roofs' were bulging. These were 1000uF 16v radial electroltics - a similar repair to the above cost £5 (say $10) inc P&P to get replacements for both monitors and both work fine now.

Had the same problem, monitor went dead so I took it apart and the two capacitors had raised roofs. Got 6 new ones from Ebay for £2.10 all in and replaced two. Works brill, if they go again I would replace with 25V though. Thanks jungleg49

Thank you for answering those questions. That usually indicates it has a bad power inverter. From what i can tell, that monitor is a few years old. You can attempt to find an inverter online to replace it yourself (usually about $50 if you can find one) since its no longer covered under warranty, or put that money into getting a new monitor.

My AOC screen goes black after about a few seconds after booting.


Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer or service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

SCREEN GOES BLACK AFTER A FEW SECONDS AFTER TURNING MONITOR ON.


More often then not, this is attributed to a failing Backlight Inverter. A Backlight Inverter, is a power board mounted below the screen that actually send power to the Lamp inside the LCD itself. Check to see, when it goes out if there isn't still some images faint in the screen. If this is the case take it to a local repair shop and have them order one and replace it. repair cost for this shuold be around 65-100 dollars.

If this helps, please rate my solution. Have a great day.

Monitor goes blank less than a second after turning on.


Beautiful screen, lasts about for a few minutes, goes black. Power button still green. If I turn it off, and then back on, it works again for a while. Any ideas?

RE:monitor goes black


Monitor going black after a few seconds can be causd by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4 bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.
