During the past year, we have been found that various 2010 TV models do not have the correct test patterns listed in
their service menus. To ensure you have the correct test pattern for a given TV, download the TV’s latest firmware if the
TV does not have the latest firmware installed. The error is rectified in all the latest firmware versions for all models .
What does this mean to you in the field? For PDP and 120hz/240hz products, this means simplified troubleshooting. If
you are not already aware of the test patterns, now is the time to get acquainted with them. They are a valuable tool for
isolating board failures between the main board, LVDS cable, T-con/FRC, and panel.
See the flowchart below for a basic overview of the video processing flow and how it relates to the test patterns. Note
that the flowchart is accurate for PDP TVs except where it mentions FRC test patterns. For PDP TVs, use Logic test pat-
terns instead.
