Bad inverter where can you buy replacement parts for these kds monitors

You either have a bad inverter or a bad backlight tube.
The parts are relatively inexpensive but depending on your technical skill level it may not be worth repairing

The inverter is fairly easy to replace but the backlight will be a pain as the light tubes are extremely thin and break very easily.

1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.

Sure, You have many choices out there. I even saw a repair kit on Ebay for your monitor. You just can't purchase on this site.

necesito el diagrama de conexion interno para lcd kds 700p. i need de pinout tech info for lcd monitor kds model 700p myy wire is broken........ i just adapt a new part used,,,?

You can try if you have proper tools and soldering skills.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, 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.

Power supply filter caps will be he first thing to check, look for leaking/bulging tops.

The most common problem with LCD monitors is the capacitors that are on the power pack. the pack usually looses or pops as we say 2-6 of them after 3-5 years. its almost a certainty after 5 years. a component repair tech can replace these but unless you can find some one like me who will do it for cheap to save the landfill you most likely will buy a new one.

Instructions follow, RESULT "Replace and never buy a KDS USA Monitor again (less than 3 years usage)."

I have the sameproblem soI plugged in a HP 1702 after 2 days it started doing the same thing. I am using an old school kds with no problems.

Could it be a bug in the system with flat screens.

First make sure you have the monitor cables correct. Try another monitor hopefully works so you can go into your device manager and make sure the right drivers are loaded and that your monitor is listed. You may do some research because I'm not sure but I think your monitor uses a back light & an inverter which is replaceable and not usually a difficult job or to expensive. Labor of coarse cost more than the parts. Monitors use a video card or on board video so make sure these are not the problem.
Are you sure its not in wake mode in the bios?
If you shine a light on the monitor when the comp. is on and the monitor light is on you may be able to see your screen. That would be the back light.
When if all and what was going on when it stopped working?
