I put up the grid found here:http://psleng.dyndns.org/files/tv_test/grid.jpg
I did notice that from the top right to the botom right, the pattern does not look exactly the same. Same is true from top right to top left. Is this the proper geometry test?
Also, I put on CNN and watched a ticker go across the bottom. It looked good to me - saw no issues with it.
Thanks in advance.
I haven't done this as I don't have the tv yet, but based on what I've read I believe you measure the line on the top for the distance from the bezel to where the line starts on the one side and then do the same on the other side for the horizontal line. This should tell you how far off the it is any thing under 1/4" is within specs IIRC (sounds like it might not be to bad as you don't see it with the ticker, but find another channel that has it running across the top also). You also need to check a SD source for a 4 to 3 frame to look at the vertical lines on the picture frame (frame meaning the projected image frame) to make sure they aren't pushed in or bowed out also IIRC. Hopefully I'm not stearing you in the wrong direction here.
You can also pull up the service menu to check your geo.
How do I access the service menu?
Be careful in the service menu, if you don't know what you are doing, you can screw up your set!
With the TV off, press Mute, 1, 8, 2, Power on the remote. Caution, this will cause all of your user picture menu items to reset to their defaults. So, you will have to redo your contrast, brightness, etc. settings whenever you go to the service menu. Write them down before hand!! To back out of a service menu item, hit the menu button
- What are all of these service menu items?
See the list here thanks to ztkp01.
Need to start working on a description of service menu items, if anyone would like to contribute...
- How can I bring up some test patterns from the service menu? (Might be useful in a store to check geometry)
From the service menu, you can get to the test patterns by going to the DDP3021 menu, and choosing Test Pattern (DDP). You can then right arrow through various test patterns. There is one for adjusting the picture position that may be useful for checking geometry.
