HITACHI 11AK19

TVs are assembled on a universal-type chassis AK19. This allows
use picture tubes with different screen size without making
significant changes to the scheme. TVs also use chips
controlled via I2C. This allows for adjustment televizo-
ra directly from the remote control without having to remove the rear cover.
Therefore, if the TV works, but it disrupted the consumer charac-
istics (change white balance, image size, image centering,
zheniya, etc.), it is necessary to try to adjust with the remote control.
5.1 Involvement adjustment mode
To enable the adjustment, press the blue button
remote control, while on the TV screen menu should appear USTA-
Novki the following:
INSTALLATION
Customize ...
PROGRAM ...
Configuration ...
Click the button in series 4, 7, 2 and 5, the remote control. You should
appear on the Tools menu of the following form:
SERVICE
ADJUSTMENT ...
OPTIONS ...
Inscription ADJUSTMENT ... should be highlighted in white letters on
blue background.
Press the "+" remote control, and it should enable
adjustment. On the TV screen should appear the inscription "ADJUST 00"
(Regulation 00) and the scale on which is indicated by the process of adjustment.
To the left of the scale of the numeric value of the controlled parameter (mo-
Jet vary from 0 to 63). Number of the controlled parameter is chosen in
power buttons "" or "" remote control. Parameter is controlled by
the "+" or "-" remote.
WARNING! Need to remember before adjusting the digital
value of the controlled parameter, since any change in its auto-
cally stored in memory. This is necessary in order to be able to ver-
nutsya adjustment to set the manufacture of television.
Exit control is performed by pressing the "TV".
5.1.1 White Balance Adjustment
Choose adjustable parameter "ADJUST 00", "ADJUST 01" or
"ADJUST 02". The purpose of these adjustments:
"ADJUST 00" - adjust the "red";
"ADJUST 01" - adjusting the "green";
"ADJUST 02" - adjusting the "blue".
By adjusting these parameters to achieve the white balance.
Adjustment must be performed on the signal "white box".
5.2.2 Adjustment of AGC
Choose adjustable parameter "ADJUST 03". This adjustment recom-
mended to perform to remove the back cover. To the antenna input tele-
tensor give the signal level of 60 dBmV (recommended frequency channel 12,
Recommended signal - "Color bars"). Digital voltmeter measured
rit voltage on pin 1 of SLE. The voltage should be 3.7 V. In the case of
need to put it, adjusting the value of "ADJUST 03". Verify
image quality when the signal 90 dBmV.
5.2.3 Adjustment of AGC-type PLL for SLE

parameter "image size" of 4:3. Adjustment is recommended conduction
dit on tap "UEIT" or "mesh field."
5.2.12 Adjusting the size of the horizontal picture format
4:3 (only for CRT 110 °).
"ADJUST 17" - adjusting the size of the image horizontally to
4:3 (only for CRT with a screen size of dia-
estrus 63 and 70 cm). Acts in cases where in the image was
set to "image size" of 4:3. Adjustment recom-
mended to carry out a signal "UEIT" or "mesh field."
5.2.13 Adjusting the width of the parabola to the aspect ratio 4:3
(Only for CRT 110 °).
"ADJUST 18" - width adjustment of the parabola for the format of images
of 4:3 (for CRT with a screen size 63 and 70 cm).
Acts in cases where in the image was set para-
meter "image size" of 4:3. Adjustment is recommended
on tap "UEIT" or "mesh field."
5.2.14 Adjustment of the parabola at the corners to 4:3

meter "image size" of 4:3. Adjustment is recommended
on tap "UEIT" or "mesh field."
5.2.15 Adjusting the keystone to 4:3 (only for
CRT 110 °)
"ADJUST 20" - trapezoid adjustment for aspect ratio 4:3
(Only for CRT with a screen size diagonal 63 and 70 cm). The action of
exists in cases where in the image was set to
"Image size" is 4:3. Adjustment is recommended for
signal "UEIT" or "mesh field."
05/02/16 adjustments for aspect ratio 16:9

"ADJUST 23" - vertical size
"ADJUST 24" - S-correction
"ADJUST 25" - vertical alignment
"ADJUST 26" - horizontal size (picture tubes for 110 degrees.)
"ADJUST 27" - width of the parabola (for the picture tube 110 degrees.)
"ADJUST 28" - a parabola in the corners (for the picture tube 110 degrees.)
"ADJUST 29" - trapezoid (CRT for 110 degrees.)
These adjustments apply to cases where the menu
image was set to "image size" 16:9.
These adjustments are not essential, since the transfer of form-
Volume 16:9 are not transferred. The value of these parameters
change is not recommended because of their proper setting can be
only with a special generator.

... , Chassis: F1x, F2x, F4x, percent.: SAA5288/90PS.
In _tabl. 1 shows the model of TV, chassis, and used types of microcontrollers.
All adjustments are related to service mode, performed with a standard remote control
type FX700 RCHU or FX701 RCHU. Both have the same remote control button layout, but
different symbol buttons (one button on the remote symbol in the form of words, another - in the form
characters).
1) To activate the service mode jumper to close pins 2 and 3 of connector P701. Jumper
should be during the whole period of time adjusting TV in service mode.
Initialize memory EEPROM:
After replacing the EEPROM with a new, micro-controller automatically enters it in the initial
production values. This process takes a few seconds. If the
At each turn on the TV writing process in memory is repeated, it could mean that the chip
Memory is faulty.

• Please click on teletext (UPDATE) _sm. Fig. 2 and hold it for as long as the TV does not
  

goes into standby (within three seconds). When you turn on TV will automatically
initialization procedure performed.
Adjusting the settings in service mode:
On the left side of the screen displays two numbers in hexadecimal code. The first number denotes
parameter number, the second - characterizes the actual value.Full list of available options, as well as primary production values ​​for different
diagonals of the CRT is presented in _tabl. 3.
! After setting a designated''1A''available next three parameters that instead of numbers
lettered:
Text Mode - Contrast Text.
Ex - Information (CPU) of the type of tuner: 00 - only for UHF, 01 - multiband.
AV - Information (CPU) of the nests used: 00 - SCART, 01 - SCART input, plus
phone.
Service adjustment:

• Selection of parameters of buttons P + / - remote control or SELECT button on the keyboard of the local bar.
  
• Adjusting the parameters button VOLUME + / -.
  
• Storing all the settings made at the same time TV button the remote control.
  

After storing the on-screen message appears: STORED.

• The power button and teletext button 0 in service mode, used for serial perklyucheniya
  

programs.

• Button NORMAL (normalization) is to call the production values ​​of the controlled
  

parameter.

• Numeric buttons 1 ... 8 can be used to switch individual bits installed
  

values ​​(all values ​​are written in one byte).

• Button 1 is responsible for the most significant bit. For example, if the displayed byte is equal to FF, the
  

After clicking on a byte value is changed to 7F (in binary notation this corresponds to
Change byte 11111111 to 01111111).
Mode self-test:
In case of failure, which can identify the controller, TV will automatically
switched to standby mode, and a glowing LED will flash. Fault detection
determined by the number of flashes (error number) LED _sm. Table. 2.
Additional information
Limiting the adjustment range of sound:
This function is active or disabled.
To include the following:

• Click once on the _sm. Fig. 1
  
• Use the - or + to set the nominal level of sound without any distortion.
  
• At a time when more information OSD on the screen, press MUTE.
  

The confirmation of the operation that will correctly display the symbol Reg. Volume on the rightside of the scale.
To disable the repeat vkyucheniya.
The confirmation of the operation that will correct the disappearance of the character Reg. Volume on the right
