Question about Acer AL2416W 24 in. LCD Television
I'm getting intermittent display black-outs. The power indicator remains green, so that means it's getting power, and valid video signal. Most of the time, powering down to reset the monitor will resolve the issue; - but sometimes I'll need to leave it off for 1/2 hour before it'll start working properly again. A real BIG annoyance!!!
PS. Its not a backlighting issue, since I don't see any 'shadow pictures' during the black-outs, just no display.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Your post/description of "No Signal" and power LED changing from green to amber is indicative of just that - the monitor is not receiving any signal from the video card of the computer or the signal it is receiving is beyond its capability.
Just to verify that it is indeed the PC;'s setting that is the root of the problem and not an internal fault within the monitor, pls:
1. lower the screen resolution of your desktop's properties.
2. it may also be of help if you likewise lower the screen refresh rate.
Both of the above may be adjusted through the appropriate settings in your Display Properties.
If your concern has not been corrected after completion of the above procedures, pls post back details of your video card (brand/model), display properties settings: a) screen resolution, color quality and Advanced/Monitor screen refresh rate.
Hope this be of initial help/idea. Pls post back as requested, how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FIXYA.

I see many monitor with that trouble.
When you turn on comp., you can have a picture on monitor about 10-30 min. and that go in black screen, or If you change resolution again go in black screen.
You must repair monitor or bay another.

The problem can be the 18 or 24vdc power supply is bad or the backlight inverter board is bad. You need to open it up.

Sounds like the monitor is dying, if it starts to die more and more often you will likely have to replace your monitor before it goes completely out. There are not many ways for a user to repair a monitor, unless the problem is with the computer, which you could test by connecting a different monitor to the computer for a while (if available). Hope this helps!

In most cases the standby light might blink with different rapidity to indicate a fault relevant to the processor. It is possible that most of these indicate that there are errors in the processing section . Since there is a possible short or leak in the circuit the output driver section can take in huge current to trip the SMPS or from advice from the micro processor. Remove the power plugs and make sure that high voltage sections are discharged of the potential stored in capacitors. Look for visible signs of leak or of busted capacitors. Look for bulged capacitors or damaged components- burnt or busted. Use a multimeter to check the continuity or shorting in components, if so detach from circuit and test . If the voltage builds up and the set power ON and then shuts up then the suspected section must be checked in detail.
The processor must have the +5 voltage to the function properly , the +B and secondary voltages also must be checked to infer the fault. Trace with caution and in running through the signal path , circuit trail.
