Gateway HD2200 Won't stay on

First of all, you need to detached the monitor power connection and re-attached it after 5 minutes and check if the monitor works fine.
If issue persists, you need to make sure if any custom settings are made for monitor display power saving mode. To help you find these, please follow the steps mentioned below:
- Click the Start button. Select 'Control Panel' from the Start menu pane.
- Type 'power options' into the search box. Click 'Power Options'.
- Click 'Show Additional Plans' in the 'Select a Power Plan' section.
- Click and enable the 'High Performance' radio button.
- Select the blue 'Change Plan Settings' link next to the High Performance setting to open the plan settings editor window.
- Change the setting beside 'Turn Off Display' to 'Never' under both the 'On Battery' and 'Plugged In' headings. Change the setting beside 'Put the Computer to Sleep' to 'Never' under both headings.
- Click 'Save Changes' to implement the setting.

Looks like there might be issues with your cables. Try to replacing them and see if it helps out the issue.

Power board capacitors. Easy fix with some soldering skills.

It sounds like the lamp for your monitor is no longer receiving power. While you can attempt to fix this issue yourself I wouldn't recommend doing so as it doesn't mean it will work after you attempt it.
If the monitor is under warranty still then you should contact the manufacturer about a RMA. If the monitor isn't under warranty then you should purchase a new monitor.

Sounds like you faithful Gateway monitor has died.

Hey there,
This cable can be purchased on many sites online

Hope this helps!!

power ir down and then leave it for approx 3 hrs.

or use the reset button from side of the screen, or at the bottom

Probably got some bad caps on the power supply.
if you would like details email me at [email protected].
be glad to share what i know on your monitor.

Connect the monitor that works.

In the "Advanced" settings for the video-card,
set the "refresh-rate" to 60 Hertz.

Connect the other monitor -- it _very-likely_ will support a 60 Hertz refresh-rate.

Hello,

The next thing to try would be to resolder all of the connections on the transformers in your monitor. If you can take a few pictures of the board and email them to me I will mark the points to check and send it back to you.
