Monitor goes black after a few seconds

I have an Acer AL1711 monitor, I'm pretty sure I have to replace a couple capacitors on the board, but I'm not sure which ones. Can anyone tell me where they are located?

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

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:

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Acer al1711: two monitors with same problem


Hello,

The most likely cause is blown capacitors on the power supply/inverter board. Go to our web site at: www.ccl-la.com/badcaps.htm we have pictures of what the capacitors look like when the blow out. We also have some dis-assembly guides that may help you. Just open the back of he monitor and look at the board, replace all the blown capacitors that look like the ones in the pictures and you should be back going. The values hat you will need are going to be marked on the sides of the bad caps. Be sure to use a low ESR and high temp replacement or you will have to do this again in a month or two. We carry the proper caps in stock if you want us to supply you with them. The caps at Radio Shack will not do. When you replace the bad ones be sure to install the new ones with the polarity stripe on the side going the same direction as the old ones come out. If you have any additional questions just let me know.

I hope this helps, if you please rate our solution.

My Acer AL1711 LCD monitor blacks out every 2 seconds. I like to try to replace the capacitors in it as it has been tried by few people here successfully. To tri this I took the 4 screws off in the back of...


take a flathead screwdriver and place it anywhere where the front bezel and back, you can start on the top, bottom, or either side of the monitor, place your flathead screwdrier and place it in any part of the **** and twist your screwdriver, this should start releasing some of the clips. I had to do this with several dell lcd monitors to get into them. Keep in mind after this there will be more screws to take out to get the lcd out of there.

Monitor goes black after a few seconds


I have the same problem on my Acer AL1711. The monitor was out of warranty so I opened it up and found one of the 1000 mf capacitor almost ready to pop. A 50 cents replacement from allelectronics.com fixed the problem.

Not recommended for anyone without experience soldering electronic components to PCB's.

We have repaired a couple of these. R1 on board normally burnt also C6 and C22 bad on inverter board. Replace these and it will probably work. R1 is 10 ohm. Capacitors are 220uf 25v.

What is wrong with my AL1711


This is possibly an inverter. When the monitor goes out, examine the LCD to see if you can see a faint image of the video being displayed. IF so, replace inverter. If not, possibly a bad LCD or video circuitry.
