Shell Command Buttons
Use the Pixel Locator to track and mark
individual pixels that may have failed.
For example, if an entire module fails,
an empty square box appears on the
display. For individual pixels that fail,
the display appears to miss small
portions of an image.
Note: The sign service must run for the
pixel locator to work.
To run the pixel locator diagnostic
1. Click Diagnostics > Pixel
Locator. Refer to Figure 13.
2. Select the desired sign from the drop-down menu.
3. Use the [up] and [down arrows] to increase or decrease the Row number in the Pixel
Location box. Use the [left] and [right arrows] to increase or decrease the Column
number. The Pixel Position in Driver Size and Driver Location adjusts accordingly.
Select the row and column number that corresponds to a failed pixel.
4. Click Stuck On [F5] to mark a pixel that remains on, or click Stuck Off [F6] to mark a
pixel that remains off.
Note: Marked pixels will be temporarily saved to a list, which can be printed out.
5. After identifying the failed pixels, click Verify to view the list.
