Dynon Avionics released a Revision B of the SkyView Display Circuit Board Replacement Technical Service Bulletin on March 4, 2013. This Revision B supersedes and replaces an earlier version of this bulletin that was originally released on Feb. 11, 2013.
The original bulletin specified a SkyView-based on-screen detection method to determine whether or not a display was affected. However, displays that were thought to be unaffected based on the on-screen detection method may actually be affected by this bulletin.
Therefore, ALL SkyView displays, whether or not they were already checked against the original service bulletin on this topic, must be re-checked using the updated instructions that are available at SkyView Display Circuit Board Replacement - Revision B
