AK19 CHASSIS MANUAL ADJUSTMENTS PROCEDURE In order to enter the service mode, first enter the installation menu (or press blue button on the remote control handset) and then press the digits 4, 7, 2 and 5 respectively. For ADJUST settings: Select Adjust using or button and press or button to enter it. To select different adjust parameters, use or button. or button. To change the selected parameter, use WHITE BALANCE ADJUSTMENT: The following three parameters are used to make white balance adjustment. To do this, use a Colour Analyser. Using white point RED, white point GREEN and white point BLUE parameters, insert the + sign in the square which is in the middle of the screen. ADJUST 00 = White Point RED ADJUST 01 = White Point GREEN ADJUST 02 = White Point BLUE AGC ADJUSTMENT: In order to do AGC adjustment, enter a 60dBmV RF signal level from channel C-12. Connect a digital voltmeter to pin 1 of the tuner. Change the AGC parameter until you see 3.70VDC on voltmeter display. Check that picture is normal at 90dBmV signal level. IF-PLL NEGATIVE ADJUSTMENT (Only with PLL tuner): Connect 38.9 MHz test pattern for PAL B/G, PAL-SECAM B/G, 39.5 MHz test pattern for PAL I or 45.75 MHz test pattern for PAL M/N, NTSC M model to Z401 SAW filter input terminals. Change the IF-PLL Negative parameter until you see IN, DOWN below. If you cannot catch IN, DOWN position this way, using a screwdriver rotate the VIF-COIL LT401 left or right until you see IN, DOWN. IF-PLL POSITIVE ADJUSTMENT (Only with PLL tuner): Connect 33.9 MHz test pattern for SECAM L model to Z401 SAW filter input terminals. Change the IF-PLL Positive parameter until you see IN, DOWN below. If you cannot catch IN, DOWN position this way, using a screwdriver rotate the VIF-COIL LT401 left or right until you see IN, DOWN. LUMINANCE DELAY ADJUSTMENT (with only TDA 8844 video processor): Y-Delay PAL Enter a PAL B/G colour and black-white bar test pattern via RF. Adjust Y-Delay PAL till the colour transients on the colour bar of the pattern become as sharper and colours between transients do not mix with each other as possible. Note: If the SAW filter is one of the G1965M, J1951M, J3950M, K2958M, K2962M, G3957M, K6256K, K6259K or M1963M, there is constant group delay distortion, so for an equal delay of the luminance and chrominance signal the delay must be set at a value of 160nS. This means the adjustment must be set to the maximum value. Y-Delay SECAM Enter a SECAM B/G colour and black-white bar test pattern via RF. Adjust Y-Delay SECAM till the colour transients on the colour bar of the pattern become as sharper and colours between transients do not mix with each other as possible. Note: If the SAW filter is one of the G1965M, K2958M, K2962M, G3957M, K6256K or K6259K, there is constant group delay distortion, so for an equal delay of the luminance and chrominance signal the delay must be set at a value of 160nS. This means the adjustment must be set to the maximum value. Y-Delay NTSC Enter an NTS
