Power Adapter Input AC 100-240V, 50-60Hz, Output DC 12V/4.0A
This may help. Just make sure you have the right dc output mentioned on the back of your monitor (12v4a or 12v5a) if any lower your monitor will shut off after displaying for few seconds then electrical smell will come out from your ac/dc adapter. When it overheats it shuts off.

Is this an external monitor cable? Where the monitor cable that connects to the computer has two USB cables attached at one end?
If so, no. You do not need to plug both ends in. If one is powering the monitor fine and you see no performance problem occurring with the monitor you are OK to plug in just one.
The extra USB end connected to the cable is for additional power supply. If for some reason the machine you are plugging into does not supply enough power to the external monitor you would plug the second end it to the machine and boost the power to the monitor.
Unplug the monitor power cable. You should never attempt to
disassemble an electronic component without first detaching it from its
direct power source.
Remove the screws from the back of the monitor and along the
edge of the screen. Depending on manufacturer and model, LCD monitors
will have screws located on different parts of the monitor's body. Once
the screws are off, use a flat-tipped tool, such as a knife or a
screwdriver, to pry the monitor open by dislodging the two halves; be
careful not to tear wires connecting the two halves.
Locate the power supply unit and take its metal casing off.
Once again, different models of LCD monitors will have the unit placed
in different locations. With the casing undone, unplug cables running
from the power supply to other internal components. Mark the cables that
you unplug from the power supply--you will have to plug them back in to
the new unit.
Dislodge the power supply from its dock. In some monitors
you might have to undo screws that hold the power supply unit in place.
Remember the orientation of the unit as it was placed, because you will
have to insert the new unit in exactly the same way.
Insert the new power supply into the dock and screw it in
place. If you do not have a new power supply, read the label on the
existing one to order a new one from the manufacturer or from a
third-party supplier. Obtain a power supply unit that is compatible with
your LCD monitor; never try to use a generic spare. After installing
the new unit, plug in the cables exactly as they were in the old unit.
Put the power supply casing back on and reassemble the LCD
monitor frame. Gently clasp the two halves of the monitor shut, making
sure you have reattached all cables that you unplugged to take the
monitor apart. Close the casing, tucking away all cables neatly so they
do not get in the way of the monitor casing.
Put all the screws back on. Once done, you should have no leftover pieces (screws or cables).
New PC,s are tested at the factory before they are shipped. So you need to check ALL your data and power cables as well as your AC power outlet before you report the problem to Gateway.
1. Does the power LED on the monitor light up after your connect it to AC power and turn the power switch on? If not, plug a lamp or other electrical device into the AC outlet you are using for your PC and monitor to make sure you have AC power.
2. On the rear of the PC make sure the the AC power switch on the power supply is in the on position. (Some power supplies do not have this switch) Also, make sure the AC power cable connector is fully inserted into the 3 pin power receptacle on the PC's power supply.
3. Make sure that the monitor, keyboard and mouse cables are connected to the proper receptacles on the rear or yur PC.
4. If the PV still will not power up, call Gateway tech support and tell them abouts the tests you have performed - they will probably arrange to send a technician to test your PC.
Sounds like power supply or the cable may be bad. Try another monitor on same cable or same monitor on different computer with same or different cable exchanging components until problem stops. It may be the power supply to your computer is getting bad and cannot support the power requirements you need. OR, it may be that the monitor is starting to need internal component, like relays of power supplies for itself. Try the other stuff first.
Hope this helps.
for the quickest fix, you should try a new power supply cord and see if its just a bad cable. almost any monitor cable (dell brand) should work. if you do not see any of the lights on the monitor light up then you have an internal problem and it will be costly to repair. probably better of buying a new monitor.
it seems to be an issue with the power supply as you already tried replacing the motherboard
power supply will be less expensive do try to get it replaced first
do check that monitor iss fine
unplug the blue VGA cable which connects your monitor to the tower
if a 4 colored box moves all over the screen the monitor is fine
and if it doesn't
get the monitor either repaired or get it replaced.
