I have the service guide for this monitor and the values for the R811 to R814 are the same: 1.8 . The mosfet is a 2SK2645. I will like to send the pdf file, but I new in this site and I don´t know how to attach a file due the only options that I see is a link, image or you tube clip.

Good luck

Acer AL1711 17" LCD Monitor showing white screen


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

Hi, i have an acer lCD monitor model x223w, the screen light flickers for a few seconds then the moniter shuts down. what can i do to fix it?

if no any power led indicator at the front panel after of shut down, the cause could be power supply failure. you will need to remove the back cover to gain access of the internal part of the monitor. look for a blown fuse or burnt parts at the power supply board. if you have an idea about electronic parts just replaced defective parts with the same rating and value. hope this can help good luck just let me know if you need further assistance.

I have a Acer V193W Computer Monitor. When I turn it on I get a white screen then it goes black for like two seconds then comes back on with a white screen and stays on that way. What could the problem be?

The LCD panel is not getting the 5/12vdc from the logic board or the fuse on T-CON board is blown or bad T-CON board, it can also be due to bad 5VDC power supply caps in the power supply and in the logic board.
Please read my guide and look at the pictures at my photobucket.

LCD Monitor Acer AL1717 shtting down problem


Aside from the capacitor and IC, there's a relay that you need to change. You need to locate that defective relay on the PCB and replace it.

It would be best to consult the manufacturer of the LCD and get the exact part number of it.

Have a great day!

I have an Acer 1715 that also turns on, then goes dark after a few seconds. The capacitors on the AR577 supply/inverter board were good, but I replaced them anyway. There is a good write-up with photos at:

This shows the board nicely and capacitors for the 1712 Acer, which is very close to the 1715.

This didn't cure my problem, and after chasing signals, I believe the problem is a bad inverter chip. The SG6841SZ on the back side of the board is a 20 pin gull wing surface mount package that drives the FETs to switch voltage off and on to the high voltage transformer. I know the diodes and FETs work because it comes on. The transformer drive stops when the backlights go out, though the voltages are all there. The 5V drive signal from the control board is there, so the problem has to be the inverter, or all 4 FETs.

If I can get hold of the part and it fixes it, I'll post it here.
