Most common failures in these LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply C242 470uF 10V, C241 & C242 1000uF 16V, C261 & C319 680uF 35V failed as indicated in the attached picture, replace them at once.
If the power supply board is working then it is back light problem, first do a flash light test. If you can see the image in the flash light test, follow the steps how to test back light voltages: https://how-to-repair.org/repair/lg-tv-repair-manual-pdf/lg-led-tv-no-backlights-32ln5300-32ln5310-32ln5700-voltage-test-troub/2pyuXwNkBMA.html and follow the steps how to repair back light LEDs: https://www.youtube.com/watch?v=_poWTEihIJU Fix Led Backlights for TV or Monitor Lg Led Tv No Backlights 32ln5300 32ln5310 32ln5700 Voltage Test Troub Lg...

There is nothing broken, but you must become aware of the different standards in DVI connectors.
1)DVI-D which you have, does not have the 4 analog control pins around the alpha bar meaning it only works on digital devices.
2)DVI-A only has the 4 control pins and no bar, as well as a total of only 9-10 pins altogether. This is designed for analog only, and rarely see it anymore.
3)DVI-I stands for Interlaced, meaning it can work both ways, but will not fit in monitors that are set up for DVI-D because the analog pin sockets do not exist.
You can get more detailed by counting the pins in the rectangular area, if you use all 24 pins you have what is called a Dual-Link cable, so it can support resolutions over 1920x1280 if you have about 9 pins missing it is single-link and is limited resolution.
SOURCE: Any suggestions ?
hello,
firstly you check this monitor to another pc. it the same problem accure then
i thinks this problem due to falure of power supply or dead of flurocent tube. or any the vga cable is faulty.

Sounds like you may have had a power surge.??
Disconnect power and signal input.
Turn the unit off for 20 minutes or so. Check the outlet against another device. ( Light )
Turn unit on without connection to PC video.
If you get a no signal, you good to go . Reconnect. If you continue to get a flashing light on power button,
Check warranty, get it back to Samsung for repair.
Hope this has helped

I will not be surprised that it will be bad capacitors, that is the first place to check, see some samples here: http://s807.photobucket.com/albums/yy352/budm/Samsung%20Syncmaster%20214T/
