[Deflection Circuit] 20: Deflection Geometry Adjustment
Measuring Instrument Test Point Ext. Trigger Measuring Range Input Signal Input Terminal -----------------Monoscope (NTSC & HD) Video & HD Inputs

Purpose: Symptom:

To set the height, width and linearity of the raster. Incorrect height, width and/or linearity.

NTSC 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. Select and adjust each of the following items. 7 VHGT ... so the vertical marker sum = 4 8 VLIN ... so the large circle is round 1 HWD ... so the horizontal marker sum = 7 5. Save data and Exit the Service Mode. HD Mode 1. Supply a Monoscope signal to a HD Inputs. 2. Select the HD Inputs as the signal source (Input button) 3. Activate the Service Mode, Defl. Jungle Function. 4. Select and adjust each of the following items. 7 VHGT ... so the vertical marker sum = 2 8 VLIN ... so the large circle is round 1 HWD ... so the horizontal marker sum = 10 5. Save data and Exit the Service Mode.

[Convergence Circuit] 21. Convergence Geometry Adjustment
Measuring Instrument Test Point Ext. Trigger Measuring Range Input Signal Input Terminal ------------------NTSC -- None HD -- HD sync Video & HD Inputs

Purpose: Symptom:

To set the Convergence circuit geometry adjustments. Raster distortion at the top, bottom or sides of the picture.

Note: Deflection Circuit Geometry must be performed before this adjustment. NTSC mode 1. Select a Video Input with not signal. 2. Activate the Convergence Mode, Coarse Green. 3. Adjust the Coarse Green Items shown below for straight crosshatch lines. 4. Select the Fine Green Mode, a Cursor is displayed on the crosshatch. 5. Use the Cursor to adjust for straight crosshatch lines. 6. Exit the Convergence Mode. HD mode 1. Supply horizontal and vertical HD sync to the HD Inputs. Note: If an HD signal is not available, use the Conv. HD With No Signal procedure. 2. Select the HD Inputs as the signal source (Input button) 3. Enter the Convergence Mode, Coarse Green. 4. Repeat NTSC Steps 3 through 6 in the HD mode.
