Orion T2915 •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

Orion T2915 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.
ADJUST 03 = AGC
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. ADJUST 04 = IF-PLL Negative
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. ADJUST 05 = IF-PLL Positive
LUMINANCE DELAY ADJUSTMENT (with only TDA 8844 video processor):
ADJUST 06 = Y-Delay PAL

Enter a PAL B/G colour a
nd 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.
ADJUST 07 = 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.
ADJUST 08 = Y-Delay NTSC
Enter an NTSC colour and black-white bar test pattern via RF. Adjust Y-Delay NTSC 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 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.
ADJUST 09 = Y-Delay Other In case of other colour systems, enter this system with colour and black-white bar test pattern via RF. Adjust YDelay
Other 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. Normally 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.
