If it has Gateway EZTUNE anti-theft installed and you do not know the password, then you will have to contact Gateway support to give you the default password to unlock it. Is this monitor bought from someone else?

It was released about 2006.
I do hope you do have the PIN to unlock it, otherwise you will have to contact Gateway.

GatewayShield™ Security Available
Protect your hardware using the EzTune™ Anti-Theft Software and reinforced lock slots. The slots, paired with a cable lock, physically anchor your display to a secure fixture. The software keeps the monitor secure using a unique PIN code. In the event the display is removed from the PC without the code, its full functionality is disabled.

It may have hardware problem inside due to bad caps.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

You may have to contact Gateway also. Hope it will help.

Exact same thing happened to me and gateway technical support are clueless. Try this fix:

Unplug the power at the back
wait 1 minute
hold down the power button and at the same time plug back in the power cord at the back
keep the power button pressed for 15 seconds.

The best way to protect both the screen and computer is to use an anti-theft cable. The cable is secured to the screen, computer and the desk using very strong self adhesive anchor pads and is then padlocked to the desktop.

1. Before servicing the vehicle, refer to the precautions at the beginning of this section.
   
2. Record the radio anti theft code data.

Whatever you do - DON'T CONTACT GATEWAY. I am in the UK, and the Gateway support number is only available 9 - 5 (funny 'cos I'm at work then and can't access my PC), so I filled in the technical support form - waited 2 days for a reply only to be told they don't support third party software.
I had an online chat with US Gateway support - only to be told the same thing - alternatively, pay them silly amounts of money and phone the US and they will fix the problem.

The solution is to visit Portrait Displays (software developers) website and complete an online form with your problem. (This form prompts as to whether you have already contacted Gateway - so maybe they are monitoring the adequacy of Gateway support. The support from Portrait has been brilliant.

Unplug the cable from your monitor and then hold the power button while you plug the cable back in. When the monitor is fully restored,
release the power button and an anti-theft box will appear, prompting you to press the menu button at the side of your monitor. Press the menu button and you will be given a 3-digit code. Portrait need this code to give you an unlock code. Once you have the unlock code you can remove the anti-theft option.
