Hi, look for the degauss button and use it. the screen will go distorted a little then return to a good picture. if the condition you mention still exists, you need a new one. i do not think it is worth repair.as the cost of a new one is alot lower than in the past. i hope this helps you. good luck! and please rate this solution. if you need further help, reply.

Hello there is problem with my monitor LE2201W... there is lot of vertical and horizonyal lines in all colours mostly blue and dark red,picture is changing constantly,for second is OK after again blured...


There is a large board attached behind the LCD panel, the video enters and is processed on that board and distributed to the display screen, when there is a disruption in the processing it involves the panel that is tied to the main itself. If the video cable is detachable from the monitor and computer you can try to sub it for any change. Problems of this nature usually exceed the price of a new monitor and better just to replace it for a new one.

Hp2338h monitor goes to sleep all the time. When turned on it displays for a couple of seconds, then message flashes that its going to sleep. Its a not graphics driver board or power saver setting,...


I've seen on a few Windows 7 machines has been the display turning off after only 15 minutes, even though I set the Turn off the Display option to Never. Weird!
You're probably reading this because you've tried changing the power plan settings to Never for everything and your monitor still turns off! This can be very frustrating and usually occurs with new installs of Windows 7, though I've seen it happen on older installs too.
In this article, I'll go through the different ways you can fix this problem. Note that if your computer is on, but the screen is showing No Signal or No Input, you should read my post on fixing blank or black screens. Now let's go through the possible solutions.
Power Options - Control Panel First, we need to make sure everything is set correctly in Power Options. Click on Start and type in power options or go to Control Panel (icon view) and then open Power Options from there.
Click on Start, then Control Panel and then Hardware and Sound, and then click on Power Options.

Click on the Change plan settings link that is next to the plan that is currently selected. In my case, the High Performance plan is selected, so I'll click on the link next to it.

First, make sure that Put the computer to sleep is set to Never. Next, change the Turn off the display setting to whatever value you want it 10,15 min etc.. You don't have to set it to Never if you don't want to. After this, click on the Change advanced power settings link.

Expand Hard disk and then expand Turn off hard disk after. Reduce the value till it gets to Never. Click OK and then click Save Changes on the Edit Plan Settings page.
Screen Saver - Control Panel The second setting you want to check is the screen saver. Go to Control Panel, click on Personalization, and then click on Screen Saver at the bottom right.

Make sure the setting is set to None. Sometimes if the screen saver is set to Blank and the wait time is 15 minutes, it'll look like your screen has turned off.

BIOS, Graphics Card, Monitor The two methods above are the most common reason why your display will turn off after a set amount of time, however, there can be other possible causes.
BIOS - On some computers, the BIOS can have power saving settings that determine how the computer sleeps. These are called sleep modes (S1, S2, S3, S4, and S5). On some computers, you'll see an option called Deep Sleep Control. You may need to disable this in order for the computer to wake up faster.
Graphics Card - If you have a high-end graphics card installed, make sure you have the latest driver and management software installed. If you go through the settings, you may find an option that puts your graphics card into lower power mode or something similar.

Monitor - Lastly, some monitors have power saving features themselves. Usually, the monitor is supposed to go into power saving mode if it doesn't detect any input (HDMI, VGA, DVI, etc), but sometimes it happens unexpectedly.

You'll have to press the buttons on the monitor to get access to the monitor settings. Those are about all the reasons I could think of for your display turning off when it shouldn't. If you have any other questions please post them here ,Best

The monitor startup and few seconds later it turn


You are going to have to open up the monitor, please read below if you are going to DIY.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed SAMSUNG monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Monitor picture is distorted


This is an indication your monitor is on the way to failure: You can do a "degauss' which is usually powering the monitor off and then pushing the degauss button in and holding it while powering the monitor back on.
