I don't know if you ever got a response to this post since it isn't attached to the exchanges you had with someone before. Always retrieve your original otherwise the person who assisted you is unlikely to see your reply.
BTW, if you have done this by now, did it solve your problem? Often, the larger caps are not at fault but smaller ones that handle feedback in an inverter. The main filter caps are not subjected to the high frequencies and ripple currents that destroy the electrolyte in them.

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.
LCD screens and Inverters are available from these WEB sites. www.lcdparts.net http://www.yallstore.com

My Acer AL1711 goes black but the light indicator on..i've read some of comment similiar to my problem and tried to repair it..but still..it didn't work..i even replaced the 1000uf capacitor..but...


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:

You need spare lamp the test the inverter board.

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you.
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.

Had the blank screen problem. Now it won't work above 800x600 res


When I replace caps in this model, I replaced all the caps (4 (1000uF by the heat sink, 1 (470uF) by the inverter transformer) for the 5v and the 12v since you cannot 100% relying on just by looking bulging tops. I am not sure why your has 3-470uf. See my example here: http://s807.photobucket.com/albums/yy352/budm/Princeton%20VL2018W/

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.

Del e173fpc 17" power light comes on but screen black.


Hello,

The issue you have is caused by a bad power supply. If you change the following capacitors on the power board you should be back running again. C925 and C924 are 470uf 16v and C922 and C923 are 1000uf 16v be sure to use high temp capacitors not just standard that you would find at Radio Shack, if you do they will blow again with in a month or two. We have a parts kit available and I will have picture posted on our web site at :

I hope this helps, if so please rate my solution.

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.

This is a known problem with a series of components inside the monitor. There are about 11 capacitors that if replaced will allow the monitor to function properly.

The best place to go to read more is http://www.badcaps.net/forum/printthread.php?t=2658

The list of the capacitors that are bad are below with possible replacements.

C922, C925: Hermei LE 1000uF 16V, low impedance, general purpose, replacing with 1000uF 16V Samxon GF.
C201: Hermei LZ 150uF 25V, ultra low impedance, high ripple current, replacing with 1000uF 25V Samxon GF.
C924, C926, C929, C930, C932, C933: Hermei LT 470uF 16V, high ripple current, low impedance, replacing with 1000uF 16V Samxon GF.
C207: Unknown CD110 50uF 4.7uF (general purpose), replacing with a 35V 4.7uF tantalum unit (SCP/Short Circuit Protection pin on TL1451 won't get anywhere near 35V).
C907: WC (with stylized Westinghouse W) SM 22uF 50V (general purpose), replacing with 63V 100uF Samxon GF (used for SMPS controller Vcc filtering).
C905: Hermei HT 100uF 400V, standard, general purpose, leaving as is - generally no problem.

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.

I fixed my AL2021 by replacing the output caps on the power board. $4 repair. Pull the thing apart and replace the 1000uF, 680uF and 470uF caps on the end of the power board.
