Question about Acer AL1916W 19" LCD Monitor

1 Answer

Acer 1916W No image on screen any more.

I have one of these and I just LOVE this screen.

My problem is that the screen comes on for a few seoonds then goes off but the light is still green so some signal is still being received obviously.

Now it doesn't come on at all but still senses an input signal.

Could either the backlights or power supply be the problem.

Also how do you get the power supply out. I have opened my monitor up but can't get the power supply cage out.

Is there a guide to dissassemble this monitor?

    I don't have access to a camera at the moment..

    However I have removed the power supply board and it looks like the capacitors have blown. Several of them have bowed tops on them and dark marks.

    From what I have read this is a very common issue with this monitor and once the capacitors are replaced I will put the board back and see what happens.

As you can see at photos I post on photobucket.com, you will see mot monitors are bad due to bad caps. http://s807.photobucket.com/home/budm/allalbums
You should replace them with LOW ESR 105C caps, I use PANASONIC FM or FC series from DIGIKEY, otherwise they will not last.

Obviously you've checked the connections are secure both sides? - thats the usual culprit.
Otherwise take it out and leave it off (power unplugged also) for minimum 5 minutes and that will clear any memory and capacitors, then try again.

It proably has dying DC filter caps.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed ACER and other monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Acer 1916w flickering


Its either going to be a problem with puffy capacitors on the main board or the lcd is going bad on it cause the backlight can't stay on.

The cost of fixing the monitor may be more then what a new one is worth but you wouldn't know unless you bring it to a repair shop and have them look at it.

Try another known working monitor to see if you get the same symptoms, if they go away then you know the original monitor is bad. if you get the same symptoms then the video card is bad.
