Re: samsung syncmaster 175v
This is most probably cause by one or more Faulty Electrolytic Capacitors, I find these are the MOST commonest form of "Fault" in these LCD's TFT's units. I ususally simply replace "On Spec" all High Value Electros, in fact ALL Electro's are suspect and often I just "Shotgun" and replace 'em all. Usually fixes all problems. Always use High Temperature Caps.

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. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net
It is the picture picture board on your monitor that is
malfunctioning, since the power led or button is on, but the display screen goes blank after few seconds, it means the
board of your monitor has developed fault.
The best thing for you
do now is to take the monitor to a local repairer within your vicinity
or any service center
to help with the replacement of the picture board
because the fault is not something you can fix yourself, in order not to
Have you gone into the BIOS to make sure there aren't any power managment features? Do you get the same thing happening if plugged into a different wall socket? Sometimes bad power surges can cause this problem. Other issues have been known to arise from motherboard problems. Or NIC power settings...strangely enough...a quick way to test if it's NIC related might be too unplug any cables from the NIC to see if it stays on or not? There are power settings on NICs in advanced settings. Let me know if any of that helps and remember to rate the solutions. Thanks!
Ensure the video cable is connected (and connected to the correct video port).
Turn off the monitor using the monitor's power button and then restart the monitor.
Cycle the power on the monitor as follows:
Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
Unplug the power cord.
Wait 5 seconds.
Plug in the power cord.
Press the power button on the monitor to turn on the monitor.
One of two things happens:
The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode. For some computers, updating the BIOS corrects these types of suspend problems.
The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps to adjust the Windows display resolution to the Monitor's native (default) resolution
Connect the monitor to another computer that you know is working to determine if the monitor should be serviced or replaced:
If the monitor displays an image from another computer, you know that the monitor works. Troubleshoot the video connection and graphics adapter on the computer.
If the monitor remain blank when connected to another computer, the monitor signal processing hardware may be bad. The monitor should be repaired or replaced.
Monitor going black after a few seconds can be causd by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4
bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.
