So far so good.  I don't think it has ever been powered down since the repair, barring the occasional thunderstorm.  So it seems that this did the trick.

The next post will be when it eventually eats itself.

It is a cold cathode back-light after all and has been powered on at least 8-12 hours a day since I bought it 10 years ago.   So... see you in 2-4 years?  

I really like this monitor actually.  One can only hope.
