Q: flashing error codes

I have an older cinema display and am bringing it out of retirement.  When I connected to the computer I get the notorious short-long-short flashes. and, of course, the display remains dark.  As I recall when I used this monitor previously, I had the same problem but It was fixable by following a specific sequence for connecting.  I have researched trying to find the definition of the error code -- supposedly contianed in artnum=88366 but cannot for the life of me figure out how to get this document.  I am very new to this, so ANY help will be appreciated.  Jack

    Thanks for the info.  My flash sequence was short,long,short.  As i said, a few years ago there was a sequence that corrected the problem.  After some experimenting, I found it.  When both computer and display are connected, I turned on the computer.  I got the short,long,short seauence.  I then removed the power cord from the brick and then reconnected it.  The display worked.  This is as I remember.  Ohters with a similar problem might try this.  Thanks for your help,  Jack
