This is most likely the power inverter board in the monitor - this is common in many monitors. If it started taking longer and longer to display an image, and the power light is blinking on-and-off, that's the problem. You can confirm that it's the monitor and not your computer or the cable by plugging in another monitor if you have one to try. If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old it is, you may find it better to just replace it with a gently used one from ebay.

Please try to connect your monitor to another PC, if still the problem exist, then probably an internal electronic part/s is cold soldered / defective, which I suggest to bring the unit to an authorized service center to fix the problem. regards

SyncMaster 712N monitor problem


I've had a similar problem. I took apart the monitor (it was out of warranty by that time anyway) and found the lamps would not stay on. They'd flash for a split second before remaining unlit. I tried hooking up another LCD monitor's lamp to the Samsung, and even though I knew the other lamps worked fine, they exhibited the same behavior. Looks like something's wrong with the circuitry. The LCD actually does display the desktop on screen correctly. It's just the lamps refusing to stay on.
