Model: KW-34HD1 No. 496
Subject: Test Patterns Available From Digital Date: August 11, 2000
Receiver/Decoder Box.
Symptom:
(****) The digital receiver/decoder box (also known as the set-back box or "SBB") included
with the KW-34HD1 can be used to generate test patterns for both standard definition
and high definition adjustment modes if the SBB firmware version is 1.51 or
higher.
The test patterns are viewable on the KW-34HD1 only; they cannot be viewed
on any other model TV.
Solution: Follow the procedure below to determine the SBB's firmware version and to use the test
patterns for adjusting the TV.
Identifying the version of firmware in the SBB:
a. Enter the service mode (refer to page 36 of the service manual for instructions on using the
service mode if necessary).
b. Select device item "DTV".
c. Select register item "AGCL".
d. Set the data to "1".
e. Read the SBB firmware version at the bottom of the display.
The SBB firmware is displayed in white characters in the following format: "nn.nn/nnnnnn,
date of firmware, time of firmware"
Example: "02.20/00090 Nov 03 1999 14:23:19"
The version of the firmware is the first 4 characters. In the example
above the version is 02.20.
Do not confuse the SBB firmware version number with the TV's firmware version which also
appears on the display at the same time. The SBB firmware version appears in white
characters, the TV firmware version appears in green characters.
Using The Test Patterns
Checking picture size, position, geometry and convergence (NTSC FULL mode)
1- Tune the TV to a DTV channel, then turn the TV off.
2- Enter the service mode and select device item "DTV" and adjustment item "AGCL".
3- Change the data of adjustment item "AGCL" from "0" to "3". This brings up the first of the
built-in test patterns (color bars in 1080i full-screen mode).
The rest of the patterns are as follows:
Reference: PRINTED IN USA
TV Products Service Bulletin No. 496
Data "4": Cross-hatch with picture size markers, 1080i full-screen mode.
Data "5": Cross-hatch with stars, 1080i full-screen mode.
Data "6": Diagonal lines, 1080i full-screen mode.
Data "7" White raster, 1080i full-screen mode.
Data "8" Grey scale, 1080i full-screen mode.
Data "9": Color bars, 480i 4:3 mode.
Data "10": Cross-hatch with picture size markers, 480i 4:3 mode.
Data "11": Cross-hatch with stars, 480i 4:3 mode.
Data "12": Diagonal lines, 480i 4:3 mode.
Data "13" White raster, 480i 4:3 mode.
Data "14" Grey scale, 480i 4:3 mode.
Data "15": Color bars, 480p 4:3 mode.
Data "16": Cross-hatch with picture size markers, 480p 4:3 mode.
Data "17": Cross-hatch with stars, 480p 4:3 mode.
Data "18": Diagonal lines, 480p 4:3 mode.
Data "19" White raster, 480p 4:3 mode.
Data "20" Grey scale, 480p 4:3 mode.
4- Change the data to "10" so that the 480i cross-hatch is displayed.
5- Change the TV display mode to "FULL"
6- Use this pattern to confirm (and adjust if necessary) picture size, picture position, geometry,
and convergence in the NTSC 480i FULL mode. Refer to picture # 1 for using the SBB built-in
patterns for confirming the picture size. Refer to the KW-34HD1 adjustment manual for the
actual procedures. The part number for the KW-34HD1 adjustment manual is HTVADJ199.
NOTE: The adjustment manual called for a different signal source for making these
adjustments because the internal pattern generation capabilities were not available at the time
the manual was written. The picture size markers included on the SBB's internal test patterns
make it much easier to adjust the size.
7-Exit the service mode.
Checking picture size, position, geometry and convergence (NTSC NORMAL mode).
1- Tune the TV to a DTV channel, then turn the set off.
2- Enter the service mode and select device item "DTV" and adjustment item "AGCL".
3- Change the data to "10" so that the 480i cross-hatch is displayed.
4- Change the TV display mode to "NORMAL".
5- Use this pattern to confirm (and adjust if necessary) picture size, picture position,
geometry,and convergence in the NTSC 480i NORMAL mode. Refer to picture # 2 for using
the SBB built-in patterns for confirming the picture size. Refer to the KW-34HD1 adjustment
manual for the actual procedures.
6- Exit the service mode.
Checking picture size, position, geometry and convergence (NTSC ZOOM mode).
1- Tune the TV to a DTV channel, then turn the set off.
2- Enter the service mode and select device item "DTV" and adjustment item "AGCL".
