Item Adjustment of V-S.COR & V.LINEARITY

Measuring instrument

Test point

Adjustment part 10. V-S. COR 11. V-LIN

Description

"

When the vertical linearity has been deteriorated remarkably, perform the following steps.

TOP

38. Receive a cross-hatch signal. 39. Select 11.V-LIN with the FUNCTION UP/DOWN key. 40. Set the initial setting value of 11.V-LIN with the FUNCTION - / + key. 41. Select 10.V-S.COR with the FUNCTION UP / DOWN key. 42. Set the initial setting value of 10.V-S.COR with the FUNCTION - / + key. 43. Adjust 11.V-LIN and 10.V-S.COR so that the spaces of each line on TOP, CENTER and BOTTOM become uniform. NOTE : Do not adjust �PANORAMIC� & �16 : 9 ZOOM SUBTITLE� mode. * For JK chassis On account of CRT (ITC), set V-S.COR except for "PANORAMIC" mode to the minimum. When adjusting "PANORAMIC" mode, slightly expand the space at the CENTER while taking the circularity at the CENTER into consideration.

CENTER

BOTTOM

At first the adjustment in 50Hz-PANORAMIC mode should be done, then the data for the other zoom mode is corrected in the respective value at the same time. And confirm the deflection adjustment initial setting value in 60Hz(NTSC EXT mode) PANORAMIC mode. If the adjustment in 50Hz each zoom mode has been done and stored, the data for the same aspect modes in 60Hz is corrected in the respective value. Only the data for the other aspect mode in 60Hz is corrected for itself.
