My screen is black and wont power off


replace the cable that goes from your monitor to PC. Especially if you have a powered mini display adapter cable (if you have a video card that supports multiple monitors you will have a mini display powered adapter cable ) these power adapters burn out easily. 2 of mine were defective out of the box, I discovered defect by pure miracle.

Hello,

There are several Mag monitors that use external AC adapters that plug into the VGA cable. Look on the blue connector and you should see the hole where the adapter plugs. The adapter is 12v 5 amp such as this one.

Which version of the monitor do you have? Built-in power supply or external AC adapter?

or AC adapter: http://www.usadapter.com/LCD-AC-Adapters/AG-Neovo-F-417-LCD-Adapter-12V-4A.html

If it uses externa; AC adapter, then you need to attach a car bulb such as 1157 using high filament to the adapter output and see if it still putting out 12vdc with load.

If it uses built-in power then you need to check the power supply section first.

Definately it's not the power supply of the computer. Maybe it's the vga card of the computer. Try using the monitor with another computer or another computer at the monitor.

Monitor not turning on


If the adapter goes out its most likely the adapter. Check the voltage on the adapter and try and match one up on the internet as the one you order from the company will most likely cost 10x more. You need to know the output voltage and amps.

Flashing on and off


Is the monitor a LCD monitor and does it uses a power adapter?
If this is the case then it could be the power adapter that is faulty or if it is underpowered and the thermal overload cuts in then it switches off and when it cools it switches back on again.
Check the monitors power specs and the adapter should match the power requirements of the monitor or greater (ie. the voltage should be the same but the current rating should be the same or greater).

I did not have a power adapter for my lcd monitor but after 2 weeks of searching stores, internet and universal adapters I found the power adapter for my specific monitor on ebay. If that doesn't work I would suggest a universal power adapter.
