• White Balance Adjustment
  This adjustment requires that the serviceman use skills in observing what a screen without colour should look like.
  
  1. Enter the service mode.
  2. Apply a monoscope pattern to one of the video inputs.
  
  
• High Light White Balance Adjustment
  
  1. Adjust Red Drive for Red and Blue Drive for Blue adjustment.
  2. Make sure the screen is not blue or red. The screen should be white in all areas.
  3. Check the monoscope pattern for a black and white picture with even shades of gray and no colour tint in the picture.
  
  
• Low Light White Balance Adjustment
  
  1. Adjust Red cutoff for red and Blue cutoff for blue.
  2. Check the screen for even white in all areas, no colour.
  3. Check the monoscope pattern for a black and white picture, even shades of gray and no colour tint in the low lignt areas.
  4. Repeat the High Light and Low Light White Bal ance again until the white balanace tracks from high light to low light.
  
  
• Colour Check
  Again, the serviceman ability to see colour and the balance of colour is important for these adjustments. Using a clean RF or video signal, set the colour level so that it does not saturate or appear harsh. Make sure that colour is not set so that it appears dull and washed out. Look for natural colours, try to adjust the picture to appear as a normal photograph.

5. Install Alignment Template
   Convergence Alignment Template (Parts NO.TZSC07014)
   • The Convergence Alignment Template is a grid approximately the size of the viewing screen used to ensure the proper size and shape of the alignment rasters. It is 10 blocks across by 8 blocks high. The grid dimensions will vary according to the size of the screen. Apply a Convergence Alignment Template to the viewing screen of the TV. Make sure the center lines are properly aligned. If a template is not available, one can be created by following the instructions below. Great a Convergence Alignment Template by drawing the pattern to the right in the actual dimensions on transparent film or tracing paper. Start with the Horizontal and Vertical Center Axis and work outwards until the pattern is complete. Pay close attention to the actual dimensions of the pattern.

11. Display Yellow Raster Pattern
    • Press Pattern Keys ([MUTE] on remote) as needed to display Yellow (Red + Green) raster pattern.
    
    Helpful Hint
    The procedures for aligning convergence for each raster mode is identical. First align the Green raster with a Convergence Alignment Template. Then align the Red and the Blue rasters to merge with the Green raster, using the Yellow pattern (for the Red raster). Cyan or White pattern (for the Blue raster). It is highly recommended to store often throughout the convergence procedure
12. Is Red Raster merged with Green?
    • No - Using steps outlined in 10 , align Red raster to merge with Green
    • Yes - Display either Cyan or White Raster Pattern
      Press Pattern Keys ([MUTE] on remote) as needed to display either the Cyan (Blue + Green) or the White (Red + Green + Blue) raster pattern.
    
    
13. Is Blue Raster merged with Green?
    • No - Using steps outlined in 10 , align Blue raster to merge with Green
    • Yes - Store Data
