Closed Captions
Closed captioning is a process which converts the audio portion of a television program into written words which
then appear as subtitles on the television screen. Closed captions allow viewers to read the dialogue and narration of television programs.
Using Closed Captions
Captions are the subtitles of the dialogue and narration of television programs. For prerecorded programs, program dialogue can
be arranged into captions in advance. It’s possible to caption a
live program by using a process called real-time captioning, which
creates captions instantly. Real-time captioning is normally done
by professional reporters using a machine shorthand system and
computer for translation into English.

Caption Tips
● Not all TV broadcasts include closed caption signals.
● Sometimes TV stations broadcast four different caption signals on the same channel. By selecting from
CC 1 to CC 4
while another CC might show demonstration or programming information.
● Your TV might not receive caption signals normally in the following situations.
Poor reception conditions are encountered:
1
, you can choose which signal you will receive. CC 1 is usually the signal with the captions,
Captioning is an effective system for the hearing-impaired, and it
can also aid in teaching language skills.
• The picture at left shows a typical caption.
● IGNITION:
Picture may flutter, drift, suffer from black spots, or horizontal streaking. Usually caused by interference from automobile ignition systems, neon lamps, electrical drills, and other
electrical appliances.
● GHOSTS:
Ghosts are caused when the TV signal splits and follows two
paths. One is the direct path and the other is reflected off tall
buildings, hills or other objects. Changing the direction or
position of the antenna may improve reception.
● SNOW:
If your receiver is located at the weak, fringe area of a TV
signal, your picture may be marred by small dots. It may be
necessary to install a special antenna to improve the picture.
An old, bad or illegally recorded tape is played.
2
Strong, random signals from a car or airplane interfere with the TV signal.
3
The signal from the antenna is weak.
4
The program wasn’t captioned when it was produced, transmitted, or taped.

- Connect the serial port of the control device to the RS-232C jack on the Monitor back panel.
- RS-232C connection cables are not supplied with the Monitor.
This chapter describes a subset of the Zenith standard MPI protocol. It differs from the standard
MPI communications protocol in terms of not requiring a continuous polling loop and only implementing a subset of commands and responses.
Command format is as follows:
Command byte, optional data byte, optional data byte,...., checksum. All values in hex, no spaces,
carriage returns or line feeds. The checksum is the sum of all previous bytes in the command string,
truncated to 8 bits. If a command is received with a bad checksum, it should be ignored. If the
beginning of a command is received, the entire command must be received within some timeout
period. If the timeout expires, the partial command is abandoned, and any internal buffers flushed.
Response Format: Response, Data byte, Checksum
How to connect

“E1” + “11” to get “F2”.
The TV will perform the action and will not return
a response.
03. Volume Up
- To turn the volume of the TV up, the following
string needs to be sent to the unit;
E10AEB
E1 : It is the start of the command and signifies

0A : It is the command for volume up.
EB : It is the checksum calculated by adding
“E1” + “0A” to get “EB”.
The unit will perform the action and will not
return a response.
04. Volume Down
- To turn the volume of the TV down, the following
string needs to be sent to the unit;
E10BEC
E1 : It is the start of the command and signifies
a “key” (as in front panel keys) command.
0B : It is the command for volume down.
EC: It is the checksum calculated by adding
“E1” + “0B” to get “EC”.
The TV will perform the action and will not return
a response.
05. Volume Direct Access
- To set the volume of the TV to a specific level,
the following string needs to be sent to the TV;
EAXXYY
EA : It is the start of the command and signifies
a volume command.
XX : It is the value that the TV is to be set to in
hex.
YY : It is the checksum calculated by adding the
previous bytes together and truncating.
- Valid values for “XX” are from 0-3F Hex, if the
second MSB (X1XXXXXX) is set to one, the
volume data is ignored and the TV mutes the
sound. To unmute the unit a EAcommand with
the second MSB set to 0 and a volume greater
than 0 should be issued.
Example;
To set the volume level to 29 decimal (about half
of the 63 decimal range), the data byte would be
constructed in binary as follows (MSB) 01011101
(LSB) or 5D hex. The command would then be:
● EA5D47
EA : It is the start of the command and signifies
a volume command.
5D : It is the data byte to select the volume level
and to set the value to 29 decimal.
47 : It is the checksum calculated by adding
“EA” + “5D” to get “47” after truncating the
resulting “147”.
The TV will perform the action and will not return
a response.

previous bytes together and truncating.
The data byte “XX” is defined as follows:
The upper two bits select the parameter
(00=start volume, 01 max volume limit, 10=min
volume limit) the lower 6 bits of data set the
actual volume level in a range of 0 to 3F hex.
Example;
To set the maximum volume level to 29 decimal
(about half of the 63 decimal range), the data
byte would be constructed in binary as follows
(MSB) 01011101 (LSB) or 5D hex. The command would then be:
● EB5D48
EB : It is the start of the command and signifies
a volume limit command.
5D : It is the data byte to select the volume level
and to set the value to 29 decimal.
48 : It is the checksum calculated by adding
“EB” + “5D” to get “48” after truncating the
resulting “148”.
The TV will perform the action and will not return
a response.

00=Star Volume
01=Maximum Volume Limit
10=Minimum Volume Level

07. Direct Channel Selection
- This command allows the RF channel number
to be set as well as allowing the controller to
select which base band input is active. The
command is structured as follows.
E4XXYY
E4 : It is the start of the command and signifies
a direct channel command.
XX : It is the data byte that selects the channel
to be tuned.
YY : It is the checksum calculated by adding the
previous bytes together and truncating.
In order to select different source inputs a prearranged channel number is used. The channel mapping is as follows:
Channel Number Source
1 to 125 Traditional RF
131 Rear composite Video Input
132 Rear S-Video Input
133 Front RGB Video Input
134 Rear RGB Video Input
135 Not used
136 Rear Y, Pb, Pr Component Input
137 Front S-Video
138 Not Used (Reserved for internal
139 Not Used (Reserved for internal
Note:
Not all input configurations will be available in
all products. When a non-valid input is selected the unit should remain on the current input.
Example;
To select the rear RGB video input, the data
byte would be 86 the hex representation of
134 decimal. The command would then be:
● E48678
E4 : It is the start of the command and signifies
a direct channel command.
86 : It is the data byte to select the rear RGB
input
16A: It is the checksum calculated by adding
“E4” + “86” to get “6A” after truncating the
resulting “16A”.
The TV will perform the action and will not return
a response.

08. Poll/Front panel-IR Lock Out
- This command is used to determine the status
of the TV and set the front panel keys and
infrared (IR) control. The command is issued
to the TV and the TV will return the status of
the unit as described below. If the command is
issued in the form of “A0” the front panel keys
and IR control are active and remain that way
until a subsequent “B0” command is issued. If
the command is issued in the form of “B0” the
front panel keys and IR control are disabled
and remain that way until a subsequent “A0”
command is issued. In either form of the command the TV responds with the status read
back information. A checksum equal to the
command is transmitted.
A0A0 or B0B0
09. Status Read Back
- This command allows the controller to obtain
the status of the TV. The values reported are
volume setting, current channel/input, and
input signal strength status. The status read
back command is initiated by issuing a standard poll command;
B0 or A0
B0 or A0 : It is the start of the command and sig-
nifies that the TV should return the status
of the unit to the controller. “B0” is used
when the front panel is to be locked out or
to remain locked out and “A0” is used
when the status is to be returned and the
front panel is to be unlocked or remain
unlocked. No data bytes are sent.
Upon receipt of the poll command the TV
will return the status in the form of the following command:
ABWWXXYY
AB : It is the start of the command and signi-
fies a data return command.
WW: It is the second data byte.
YY : It is the checksum calculated by adding
the previous bytes together and truncat-
ing.
206-3825
- The two 8 bit data bytes are organized as
follows:
- Data byte 1 (the first data byte received)
Bit Description
0-5 Volume level in hex,
(00=minimum, 3F=maximum)
6 Signal status (1=Good, 0=Bad)
7 Power Status (1= On, 0=Off)
- Data byte 2 (the second data byte received)
Bit Description
0-7 Channel number,
00-FF hex
Channel Number Source
1 to 125 Traditional RF
131 Rear composite Video Input
132 Rear S-Video Input
133 Front RGB Video Input
(Not used on current LCD design)
134 Rear RGB Video Input
135 Not used
(Reserved for Scan Card Products)
136 Rear Y, Pb, Pr Component Input
137 Front S-Video
138 Not Used (Reserved for internal
Y, Pb, Pr Video Input)
139 Not Used (Reserved for internal
S-Video Input)
Example;
T o determine the status of a unit that was turned on
and viewing channel 3, with a good signal, at a volume of 29 decimal the controller would issue the
following command string:
● B0B0
To which the TV would return the following string
after disabling the front panel and IR control if they
are currently active:
● ABDD038B
AB : It is the start of the command and signifies a
data return command.
DD : It is the data byte.
03 : It is the second data byte.
8B : It is the checksum calculated by adding “AB” +
“DD” to get “8B” after truncating the resulting
“18B”.
The first data byte DD hex breaks down to the following 8 bit word (MSB) 11011 101 (LSB) and the first
two bits can be read as power on, signal status good,
the remaining bits yield 29 decimal as the volume
setting.
The second data byte 03, hex breaks down to RF
channel 3.

cloth in a mixture of lukewarm water and a little fabric softener or dish
washing detergent. Wring the cloth until it’s almost dry, and then use it to
wipe the screen.
2.Make sure not to put an excessive amount of water on the screen, let it airdry before you turn on your TV.

If you leave your TV unused for a long time (such as a vacation), it’s a good
idea to unplug the power cord to protect against possible damage from lightning or power surges. If you use an antenna, you may also want to disconnect it from the back of your TV before leaving.

Image-Persistence Cause & Prevention
Image-Persistence is rare on LCDs but is something of which you, the customer, should be
aware.
What is Image-Persistence?
A residual image from a previous screen is still viewable after changing channels/inputs.
Sometimes the after image will fade away in a few seconds/minutes, but it is possible that the
image is persistent and doesn’t fade away. This problem is most common on devices that use
phosphor in the screen, but can also affect LCDs. Although Image-Persistence takes longer to
happen on LCDs than with phosphor based displays, care should be taken to prevent
permanent effects. Image-Persistence is also known as “Image Burn-In”, “Image-Retention”,
and “Image-Sticking”.
What causes Image-Persistence on LCDs?
When an LCD TV or monitor is operated continuously for a long period of time with a fixed (non-
moving) image, a trace of electric charge can build up near electrodes inside the LCD module.
The result of this is a residual image of the previous image when the screen is changed.
How do I prevent Image-Persistence on my LCD?
• Turn the device off when not use.
• Do not leave static DVD or game menus on the screen for long periods of time.
• Use a screen saver and/or power save feature when using the LCD as a PC monitor.
• Change your PC’s background wallpaper periodically.
How do I reverse Image-Persistence on my LCD?
• Leave the device off for several hours/days.
• Display a white image on your screen for several hours/days.
• Use a screen saver that uniformly “exercises” each part of the screen.
NOTE: These methods do not guarantee that image burn-in will be reversible.
Is Image-Persistence covered by warranty?
No, this is considered misuse and is not covered by warranty. Normally, only product defects are
covered by warranty and Image-Sticking is inherent to the technology used to make the display.
