I have a Samsung Synchmaster 712n. All of a sudden, while surfing the net, I got a white screen. There was no sound like a pop or anything, and it was instantaneous. Can you tell me what the problem is? Do I need to buy a new one or can I fix this one?

Re: Samsung Synchmaster 712n problem
This is a common issue with lcd monitors about 2-3 years old. The power supply has an issue. The unit sounds like it has a 1 or more blown capacitors in the power supply. If you are comfortable with working on electronics and with soldering you should be able to repair it, if not we offer a repair service. You can open the monitor case and look at the power board. There are parts called capacitors, these parts go bad and the top of thier aluminum cases. Look for parts small round parts with aluminum tops and covered in a plastic sleeve. You should see some of them with a slight dome in the top. These are the blown ones. On the side are numbers showing the value, they can be unsoldered and replaced with parts available from Radio Shack or online. If you don't feel like taking on the challenge we do have a repair service for LCD monitors, Send me an email at email@example.com and I can get you more info.

If there is sound, no doubt, its signal input is OK. The problem must be to your Tv itself. If the LVDS cable, the cable that connects between the T'Con board and LCD panel have a loose contact, this type of faultcan occur. Re-seat this cable once, and check.

Rush to claim your warranty, the only thing you should do first is make sure that the input signal is OK: Hook up any laptop to any other monitor, then immediately (i.e. without changing what the computer is showing) hook it up to your monitor.
Another option is that you have a faulty cable. If it is part of the monitor, the warranty will cover it. If it can be detached from the monitor, borrow another cable to see whether that is the faulty piece.
The power switch is a momentary tactile switch. If you want to fix it, you will have to turn it off and look at the size of the switch to try to find the replacement for it. Not much you can do but open it up to find the cause of the problem.
Open this link and make it full-screen. Watch the screen for 20 seconds or so to see if the line of lit (white) pixels remain.
If this line remains during this, and even when the the computer is first starting up, it is most likely a row of "lit" pixels caused by a faulty connection or circuit inside the display.
While you can sometimes rub the area of the screen near a single lit pixel, an entire line of them usually denotes a more complex problem that can only be fixed by having parts replaced by a technician
Note: Be sure all of your cable connections are securely fitted, and that the line is there no matter what is displayed on the display (especially at the boot screen before Windows loads).
Prior to attaching the SynchMaster and if there is another monitor, pls try lowering the Screen Resolution of your Display Properties. It may also be necessary to lower down the Screen Refresh Rates. In some video card, you may have to activate Twin/Extended view or enable the use of a second monitor assuming that your regular monitor is connected to the standard 15pin VGA and that the Samsung would be the 2nd monitor using the DVI.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
