Need new power/invertor board for Acer AL1711

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 [email protected]

Good day!!!!


if the fuse blew continuously when you plug it...


that problem is cause of shorted parts on the power supply board...the regulator (transistor)..

or you can buy a new power supply board...

IT IS A INVERTOR BOARD FAULT OR LOOK FOR SWOLLEN CAPACITORS ON POWER SUPPLY BOARD IF THERE ARE SUSPECTED CAPACITORS REPLACE THEM WITH NEW ONE IF NOT REPLACE INVERTOR BOARD.

the fuse is on the power supply board. remove the back and replace the fuse with the exact type. if the fuse is ok, you'll need a new board.

if the power led is on then thats the only fuse/if you get sound no pic then its the invertor board/switch it on does the screen flash for a second/can you see pic with a torch in background/open it get invertor board no if so

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.

Hi.  I have no experience with an AL1711 but this sounds very much like the power supply problem that affects the AL1715.

If you understand electronics then you need to check the power supply for faulty components (there were two faulty capacitors in my AL1715).  Replacements should cost about 10p each and however much time it takes.

Unfortunately if you're not into electronics then there's really not much you can do.

If you do take the back off then please post whether you can see any faulty components.

Main power supply, and or the backplane power supply, and or the backplane lamps usually cause this.

The fix is to try new modules using the process of illimination. Once the defective modules are determined, the new ones must stay in the monitor.

That is the process used to service this monitor.

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.

Most of these have inverters that power the LCD monitor more than likey that is what happened! These can be repaired, but you will get charged an nominal amount. Better off getting a new one! You better get one soon, 17" monitors will soon be out, they will no longer be sold as the standard will soon be 19".
