[Convergence Circuit] 22. Centering and Static Convergence
Measuring Instrument Test Point Ext. Trigger Measuring Range Input Signal Input Terminal -----------------NTSC -- None HD -- HD sync Video & HD Inputs

Purpose: Symptom:

To converge red, green and blue at the center of the screen Color edging over the entire picture.

Preliminary Degauss the shield cover and bracket unit of the CRT assembly ans chassis. HD mode 1. Supply an HD Monoscope signal to the HD Inputs. 2. Select the HD Inputs as the signal source (Input button). 3. Activate the Service Mode, Defl. Jungle Function. 4. Check that the data for Item 14 HPOS is set to 34. 5. Save data and Exit the Service Mode. 6. Enter the Convergence Coarse mode. 7. Check that the data for the HSTA and VTSA items for red, green and blue are set to 0. 8. In the Coarse Green mode: Center the Green Raster using the Green Centering Magnet. Rotate the Green Deflection Yoke to correct any tilt. 9. In the Coarse Red mode, use the Red Centering Magnet to converge red on the green at the center of screen. Correct any red tilt with the Red Deflection Yoke. 10. In the Coarse Blue mode, repeat Step 9 using the Blue Centering magnet and the Blue Deflection Yoke. 11. Exit the Convergence mode. SD mode 1. Supply an NTSC Monoscope signal to a Video Input. 2. Select the Monoscope as the signal source (Input button). 3. Activate the Service Mode, Defl. Jungle Function. 4. Check that the data for Item 14 HPOS is set to 35. 5. Save data and Exit the Service Mode. 6. Enter the Convergence Coarse mode. 7. In the Coarse Green mode, use Items 0 HSTA and 4 VSTA to center the green raster. 8. In the Coarse Red mode, use Items 0 HSTA and 5 VSTA to converge red on the green at the center of the screen. 9. In the Coarse Blue mode, repeat step 8 to converge the blue on the green. 10. Exit the Convergence mode.
