Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague

Capacitors kit: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you. 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

Anything magnetic close to the monitor can cause this happen. Make sure there is no magnetic interference.

the second pc probably has different settings on video card. go to display in control panel to adjust resolution and/or colors. remember all video cards are not the same. some have more memory and capabilities than others. some are just made better and age holds a factor.

First, try it on another PC, if it still does the same then you will need to open it up and look inside.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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 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.

Don't know about the 5- minute pop-up, but this is how you get it back to english:

• Turn the monitor on, connect a VGA cable and make sure it's receiving a signal.
• Press "MENU"
• Press "> Speaker +" repeatedly to get to the globe icon, and press "MENU"
• Press "> SPEAKER +" repeatedly to get to "English" and press "MENU"
• Press "AUTO" to quit out of the menu.
  

Modern monitors and desktop computer use universal power cables, so you should be able to go to an office supply store like Staples or Office Depot or an electronics store like Best Buy and ask them for a monitor power cable. It will have a three-prong end to plug into the wall and a six-sided end with three recessed slots to plug into the monitor.

If you want to buy online, monoprice.com has grest prices on cables.

Good luck.

The traditional (blue) connection is VGA and the other connection (which is white) is a DVI connection. It stands for Digital Video Interface. If you have an HD monitor and you are just using the (blue) VGA connection on the monitor and on the video card, you are not actually viewing in HD. On the other hand if you use the DVI connection with a DVI cable you will be viewing in HD and should notice the difference in the quality of your picture

Sounds like it could be that the lcd is going bad in your monitor. Try hooking up a known working monitor to your computer and if you get the video to stay on then you know the original monitor is bad. If you cant' get the video to stay on even with the known working monitor then you know that the video card inside of the computer is bad.

Open up and look for bad caps with bulging tops, check to see if you also have 12vdc feeding the backlights inverter circuits. See some examples of failed monitors here: http://s807.photobucket.com/home/budm/allalbums

clean the monitor by vaccum cleaner after opening and check if the front panel switches are faulty. if so replace it
it may possible by overtight of screw. there is also another reason for that is the microcontroller chip is faulty replace it .it may reprogrammed

Check to see if you do have 12v all the time, also check for bad caps in 12v supply and at the inverter section, see example of failed monitors because of bad caps: http://s807.photobucket.com/home/budm/allalbums

Try it on another PC first, if it still does not work, then check the DC filter caps in the power supply section first for leaking/bulging tops.

There are two places to look for the problems, the backlight inverter board and the power supply, look for burnt parts, bad capacitors, etc.

Please post back what you find.

Hold down the power button to turn it off, then hit the power button and immediately hold down the left side of the ring. Wait for the OK to disappear.
