solid when I have it connected and my screens are extended to it but cannot see because it is dark.  It flashes on for one second then dissappears.

Are you trying to power on with nothing connected? If there is a device connected, is it a PC or laptop?

It has been connected and working for quite a while a little over two years.  I have it connected to a docking station for my laptop which is a thinkpad.  Just suddenly it stopped working at all only flashes my extended screen then goes dark.  I have powered it off for an extended amount of time to see if that resets it.  I have attached other monitors to my laptop to make sure it is not the laptop.  The power source is good.  My last test would be the cable I have ordered an HDMI cable to connect that is HDMI on both ends...  Not sure what else to do and not sure how to completely reset it as the menu will not even come up.

You can test with the new cable but if the symptom is not resolved, it would require service. Keep us posted.

Well I dis test with an alternate cable and that did not resolve.  It was a USB to pin cable.  I have been given another monitor to us I am a developer and I needed it badly as working off of laptop screen does not work well as any developer would know.  I purchased it at Costco and not sure what type of coverage there is for this but it is barely maybe 2 years old.

I'm wondering if you were able to resolve the problem because I am having the same problem with a recently out-of-warranty Saumsung monitor.

I too had the problem.  I have two Samsung 24" monitors, S24E390 and C24F390 (curved).  The curved is newer.  Started blanking out, usually when I go through a reboot and restart my laptop (these are connected to my laptop so I use three monitors, the laptop internal and these two external.  What I observe is the laptop and S24 start fine, but the C24 begins to flash.  Looks like it tries to start, but cycles, flashing perhaps every 7 or 8 seconds?  Tried a lot of tricks and might get it to work eventually.  Once on it seems fine, just don't restart.

 

Solution.  I swithed the power connections on the two monitors.  Now the S24 is the one flashing, meaning the problem is with the transformer.  I'm a squirrel (my wife hates this).  When I trash anything, I save parts, like transformers.  So I need at least 14.0V DC with 2.1A for output with positive in the center.  Toughest part is getting the diameter of the connector correct.  I found an old Samsung with 14.0V DC with 1.78A.  It's working fine, bit shy on amperage but is working.  Anyway, indicates the issue is crappy transformer.  Sell a high quality monitor, but gives us a crappy transformer?  Anyway, should set you up.
