Spend $50 to $100 at any TV/video repair-shop, for trouble-shooting and repair.

Or, spend $40 to $50 to buy a used 17-inch LCD screen, or $100 to buy a new 19-inch LCD screen.

If you can make out a faint image then the fault is a backlight problem.
The fault could be an inverter board or the CCFL lamp/s

The connecting cable or the video card would be the first suspects. Try a different cable to connect the monitor first, if there is no change, the video card in the computer would be second to look at. Can simply connect a different monitor to your computer to troubleshoot this. If the testing monitor works, it will be the graphics card that is the issue.

Press the auto key of your monitor to get the best fitted resolution for your window, each monitor has a limited graphic capability of which it is designed. if the production is not ok consult your manufacturer.

If your motherboard doesn't have a VGA connection, then that means it most likely does not have an integrated video card. If this is the case, then you will have to purchase and install a video card. It is very easy and your local Best Buy should be a great resource. The geeks there are usually very enthusiastic about explaining how to do it. I use to order from newegg.com, but they have become very commercialized and overpriced, like Best Buy. You can check tigerdirect.com or my favorite Amazon.com. Best Buy will price match any items they sell, including those on Amazon. If you need further help, I’m available over the phone at https://www.6ya.com/expert/jason_3e83613ef5f2a68b

you need to give a bit better details as to what is happening

I would suggest trying your xbox on another monitor to be sure the xbox is not the problem.

You should have given us the Model, but see if this helps... http://forumserver.twoplustwo.com/48/computer-technical-help/where-power-button-samsung-syncmaster-t220hd-monitor-321111/

Click the menu button on the monitor.

This could be because the menu button is faulty contact Samsung support and they will help

Does this monitor use a separate AC power converter/power supply? If so, unplug from monitor, and test voltage on the output plug. Had a similar problem, it was the power supply, NOT the monitor.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors - Flickering screen - Screen image disappears after several seconds - Dim screen - Slow start - Power LED on, but no picture - Unusual colors and/or lines The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad. If they appear bulged on top, then they need to be replaced. New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years. Check the cables, connectors and connections. Take it to a repair shop.

No. No monitors do (that I have ever seen). If you think you have seen one that does, it was more likely an all-in-one computer.

Once you power off the monitor you will have to turn it back on. If you keep it in standby mode it will come up once you turn your computer on.

I had a similar problem with my monitor, it turned out to be a loose connection inside the unit, there is a motherboard inside the monitor, it was between this and the LCD that a cable had come loose, some dismantling of the monitor but worth a try.

Potential Problems: Cables One possibility is that your cables are messed up. The 15 pin connection cable could be malfunctioning. You should get a new cable and replace it to see if it helps your situation. If not, the problem lies somewhere else. Environment There could also be an electromagnetic interference affecting your computer. You should move the laptop around the building or room to see if the position of the monitor changes the flickering. If it stops when you change positions, then there is something in the virtual environment affecting your monitors ability to display properly. Display settings If your display settings are improperly set, then your screen could flicker as a result. You should go into your desktop main screen, click Properties > Settings > Advanced > Monitor, and set your screens refresh rate at around 85 hertz or less. Video card The other possibilities are that the video/graphics card that was integrated into your computer has stopped working. You should switch it out with a new one to see if this helps your situation. Monitor Try to plug your monitor into a different PC/laptop. If it works properly, then you have an internal computer problem. You should also update your monitor's drivers just in case.
