Samsung SA450 (S24A450BW / LS24A450) monitor turning off or no picture

The Samsung SyncMaster SA450 24" LED monitor (aka S24A450BW or LS24A450) is a great bit of kit supporting a resolution of 1920x1200 with DVI or VGA. However it started playing up, sometimes working ok and then abruptly powering off, showing the flashing Analog/Digital symbol as it scans for a signal. Other times it won't show a picture as soon as turned on - ruling out some sort of overheating problem.

I was about to pull the back off the monitor and start looking for faulty capacitors, when I spotted a firmware upgrade on the Samsung website.

You can run this Windows updater program to flash the firmware up to v1.1.7 - I did it successfully using Win7 64 bit and a VGA cable. Completely cleared up the no picture fault.
