Question about Acer AL1916B 19" LCD Monitor

2 Answers

No power the monitor use to cut off for a few seconds and come back on sometimes when first powered up then after about say 4 to 5 hours of use it would switch off at first i suspected the timer so I set it to max time till it would go off.it still did the same .so it could be the 4 capacitors close to the heatsink.but now the monitor would not power up, no power lightorange or green. so is it the capacitors that have expired and cause a break in the circuit board or the monitor itself has failed got just over one year use out of it.cant really buy one any time soon say till the new year.

Well Good news I got my monitor to work once more As I suspected it was one of those surface transistors it had burnt out on the mainboard.well I searched and searched and could not locate that part so I called the company lets say I just blew more money no help but the tech did try.WEll got the part or one simular cause as it is it would cost to high to send it to the company so I had nothing to lose. so the same time I looked on any circuit board I could get my hand on when I came on a agp card mmx4400 128mb that had stop working and bam there it was the part or one that might work so i tried it and it worked its been working now for over a week now and it works better no more shorts or cut off. so hope this might help someone out there.

Computer was on, screensaver is from my photo file - it was running. I moved the mouse to get back to the screen I had previously been on, walked away for a minute, came back, the screen was black. ...


Windows 8 especially and sometime Windows 10 may have a black screen during an update for over 15 minutes with no indication that anything is happening.

Try complete power down by holding the power key for 10 full seconds. Consider unplugging power for a few seconds after that as well.

Re-connect power, press power button to turn on the computer then if the screen goes blank, give it a half hour before looking for another solution... it may come back to you.

Screen goes black


More likely to be in the power supply/inverter baord: http://www.lcdrepair.us/E228WFPc-inverter-power.html

Look for bad caps first, but it can also be in the lamp assembly, you will need lamp tester and inverter tester to verify that.

Picture goes black at random intervals


There are 4 c5707/5706 in the inverter transformer driving circuits, the cause of the problem was due to poor solder connection in the bias circuits of the transistors. Make sure to check that after you install the new transistors otherwise you will blowthem up. Common problem with this model. When the circuit drwas too much power from the power supply, it will shut itself off to ptotect itself.
