My monitor keeps turning on and off repeatedly.

The Ballast is most likely bad. It is drawing to much power and kicking out the auto reset circuit. This is not worth repairing.
Sorry for the bad news but it happens to many LCD/LED monitors.

I got my monitor for christmas and it worked fine and to day i moveid it from my brothers room and i pluged it in and i pluged it into my laptop and it is on but it says no signal and it is pluged into...

hi what you will have to do is make sure you have swapped over from the laptop monitor to the acer monitor, as you do not say what laptop it is, i will give you an example of what you have to press to do this, if you look on your laptop keyboard there is a key that has FN on it, normally on left hand side at bottom of keys ( but could be anywhere as well ) then look at the F keys at the top, and see if you have either a key with 2 monitors on it, or a picture of a side on laptop and a face on monitor this is normally key F4, it also could be F3, dependent on the laptop make, all you have to do is press FN key keeping it pressed and then press the ( either ) F4 or F3 key, or what ever key that has the monitor icons on it, this will then switch to the main monitor and disable the laptop monitor, when you want to Finnish using the external monitor, just press the keys again in that order and it will go back to normal...hope this helps

Monitor power light blinks, then goes out. PC screen goes black.

Unplugging the power cord repeatedly is not a good idea! I hope this helps: 1- After you get a picture, go to "Device manager" (Click on Start-Programs-settings-device manager) and make sure that there is not question or an exclamation mark next to Monitors. If that is the case you might need to reinstall the driver! 2- Make sure that your video card is not faulty by hooking up a different monitor and see if it is working ok. If you still have the same problem, then you need to replace the video card. 3- Check all cables and power cords and make sure that there's good connectivity on all ends (before powering up the machine) and that there are no nicks or cuts. If possible try replacing the monitor's data cable as well. Good luck

Monitor will not turn on

It could be bad caps on the power supply. Look for bulging caps and replace them if bad.

My compiter sound is not working

If you are running windows,go to the bottom right-hand corner where the clock is and click on the little red arrow. A little row of icons pops out-there should be a little picture of a speaker, left click it and make sure the slider is all the way to the top and that the mute check-box is not selected. If that dosent help go to Start-Control Panel-Sounds Speech and Audio Devices-Sounds and Audio Devices and make sure that the Mute option isnt selected in the Volume or Audio Tabs. Also make sure that the volume slider are at maximum and that you click 'apply' for the changes to be applied.

Monitor making humming noise

First try moving speakers away from monitor a bit. Some speakers magnets actually reduce the life span off monitor. I hope I am wrong but usually a high pitch whine is the High voltage Transformer. Costs more than the monitor. All you can do is continue use till it goes. Speakers usually deteriorate the tube itself. HVT are just one of those parts that go due to use. Hope it gives you more enjoyment before it goes. Good luck and try to have a good day.

Monitor won't turn on.

Does the cord plug directly from the wall into the monitor, or is there a power "brick" adapter between?

If there's a "brick" listen to see if the hissing is coming from the monitor itself or the brick. If the hissing is coming from the brick you may just need a new power adapter.

If there's no brick or the hissing is coming from the monitor, the monitor probably needs repair. With the price of LCD monitors these days compared to the price of labor, you're probably better off getting a new LCD monitor. Just make sure you take your old one to a proper E-Waste facility so it doesn't pollute the environment.
