Is there another way to display a test pattern without going into the service menu?
You can check your set’s geometry using this image, (right click it and save to your hard disk or to a USB thumb drive and connect it to the TV). http://psleng.dyndns.org/files/tv_test/grid.jpg You you can also use the THX Optimizer test patterns in the Setup Menu of some THX DVDs. Many Pixar DVDs such as Finding Nemo have the THX Optimizer.
