use the correct caps

The most common problem with LCD monitors is the backlight. After a few years of operation the electrolytic capacitors on the power supply fail and the monitor can not be powered on or the backlight is not working. To fix it you must open the monitor and locate the power supply. Visually inspect all capacitors if they are in good condition. Faulty capacitors are deformed. Replace any deformed capacitor in the area with the red circle. Replace also the capacitor on the green circle. Its a small capacitor rated at 50 or 63 or 100 volts. This capacitor is responsible for the backlight circuit. Usually this small capacitor fails but does not deform and its hard to tell if its ok or not.

Cables, video card, resoltion. Update BIOS

chek buttons if possible can remove buttons cable

pls replace 1000/25 caps

could you calibrate your problem as screens dont require a password to use them, what is the operating system you are using

A common problem with monitors is the power supply. The electrolytic capacitors need to be replaced. The power supply is located at the back side of the monitor. The faulty capacitors are easily identified due to their shape (they become deformed after some time of use). It is common practice to replace all the electrolytic capacitors on the power supply (except the one or two big ones - high voltage capacitors). The cost of this repair is very low and it does worth to try (assuming you have soldering/desoldering skills).

Hi there, if the lamps goes off after a few seconds then it is inverter (FET driver) if it stays a while then goes off you probably have a problem with bad CCLF.Cheers

hello JareX Perhaps as far as I can tell you that your screen does not suppeot this resolution

Have you tried adjusting the screen resolution in Control Panel - Display - Settings and moving the slider on Screen resolution?
Normally a monitor such as Samsung LCD would be able to display a higher resolution.
If you cannot adjust the Screen resolution in Display - Settings then it may be that the correct video driver was not installed or is corrupted.
To check if the video diver is OK, go to Control Panel - System - Hardware - Device manager and click on Display adapter. Check that your display adapter is OK and working. If you see a yellow ? against the video adapter or a standard VGA adapter was installed then you need to re-install the video driver for your model graphics card.
