Sep 27, 2016 3:18 PM in response to mickenglishby rkaufmann87,Unless your external display is Thunderbolt equipped you likely have the wrong cable. Please use a Mini-Display adapter to (VGA, HDMI, etc..) into the Thunderbolt port on the computer and then connect the correct cable to it. Then follow the Apple's directions in Use multiple displays with your Mac - Apple Support

Sep 30, 2016 4:30 PM in response to rkaufmann87by mickenglish,★HelpfulThanks for the quick response. What is Thunderbolt? I thought it was just a fancy name for a cable. I have tried 2 different mini display to HDMI cables, with the same result. Sometimes I can jog it into life by removing and reinserting one end or the other of the cable, and other timers a restart works, but there is nothing consistent. Do you think a mini display to VGA will fix it?
Regards
Mick

Sep 27, 2016 3:44 PM in response to mickenglishby rkaufmann87,Thunderbolt is explained in http://www.apple.com/thunderbolt/.
You need an adapter cable similar to one of the ones on the following web page:

Please note that not all adapters are created alike, if you buy a cheap one then expect it to give you problems. If you buy a quality one then it should be okay. Once you have the connection made then please follow the advice letter in my initial post.

Sep 30, 2016 4:40 PM in response to rkaufmann87by mickenglish,Thanks again, I bought another mini display to HDMI cable but the problem persisted. Using the links you provided, I tried the SMC reset, which I thought had fixed it but next day - same thing. Then I tried resetting NVRAM..hooray! (well-so far) If it goes OK for a few more days I will consider the problem licked. Thanks for your input.
