Oh dear. A new year but no change to the random unsolvable tech issues that appear from nowhere. The monitor has stopped working for no reason. Powers on, power light stays on as if receiving a signal, screen is black (the "on" black, not the grey "I'm in standby" black), Nvidia Control Panel recognises the display and allows configuration, Windows beeps when it's plugged in, but just nothing to say for itself on show. Main screen is an identical panel, so although I was ruling out drivers, the main one is connected via VGA so shows as "generic" or similar in NVCP, whereas the second (blank) one is connected via DVI and shows as its namesake in NVCP. Only connected via DVI as I thought it might be the VGA socket that had failed, but doesn't seem the case. They're both Samsung Syncmaster SA450s. Googling shows other people have had similar issues, but I cannot find a single solution and I can't think of a reason this would be an issue other than a random guess at "backlight". Suggestions gratefully welcomed, even if they are of the "it's gone, chuck it" variety, so I don't waste any more time trying to make it comply. Thanks in advance!
