Eight years later, and your article is still useful. My F1703 was made in September 2003, and has been in semi-constant use ever since. A few days ago, the black screen issue began to occur. I almost gave up after learning that the recall ended in 2009, but decided to give your solution a try before junking the screen. The problem on mine turned out to be a very hard-to-miss cold solder on one of the toroids. I can’t thank you enough for your excellent article, as well as all the time and research you have spent for others on this issue.

R128 on my board is marked 3.3ohm 2WJ FO37T. Hope that helps…a year later…

You are awesome. A few weeks ago I was given a HP F1703 monitor with the 5 second blackout problem. Followed your suggestion re resoldering the coils and, lo & behold, it now works. Bad solder joits appears to be a common problem with this monitor. Thanks very much for posting it.
