PROTECTION AND LOCATION OF YOUR SET

15.1. If an outside antenna is connected to the television set, be sure the antenna system is grounded so as to provide some

protection against voltage surges and built up static charges, Section 810 of the National Electrical Code, NFPA No.
70-1975, provides information with respect to proper grounding of the mast and supportingstructure, grounding of the
lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection
to grounding electrode, and requirements for the grounding electrode.

15.2. Note to CATV system installer : (Only for the television set with CATV reception)

This reminder is provided to call the CATV system attention to Article 820-40 of the NEC that provides

installer s
guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding
system of the building, as close to the point of cable entry as practical.

16. An outside antenna system should not be located in the vicinity of overhead power lines or other electric lights or power
circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care
should be taken to keep from touching such power lines or circuits as contact with them might be fatal.

17. For added protection for this television set during a lightning storm, or when it is left unattended and unused for long
periods of time, unplug it from the wall outlet and disconnect the antenna. This will prevent damage due to lightning
and power-line surges.

a. signal and generator

The pattern of the signal should be used are White (Chroma2329 pattern113) and
Grey (pattern 114).The format of signal are respectively 720p for HDMI1
(Chroma2329 Timing 69), NTSC for AV1 (Chroma2329 Timing 37),1024×768@60Hz

(Chroma2329 Timing 14) for VGA and 720p (Chroma2329 Timing 79)for YPBPR

b. steps of adjustment

1) enter the factory menu->WHITE BALANCE, select source HDMI 1 and COLORTEMP
normal.

2) input grey signal in 720p format

3) change R OFFSET and B OFFSET to make sure the value of color coordination
equal to the value required by enterprise standard (x, y).

MS82MT-AP/LA Chassis Aliment procedure

4) input white signal in 720p format

5) change R Gain and B Gain to make sure the value of color coordination equal to

(x, y).

6) repeat step 2~5 until both of the value of color coordination of white and grey
equal to (x, y).
In addition to select COLORTEMP COOL/WARM, the adjustment method of COOL

and WARM color temperature is same with that of NORMAL. The color coordination
we recommend is as follows:

The process of adjusting ADC and White Balance automatically is out of the range
of this file. Please refer to the relevant technical file of HuiZhou factory of TCL

5. Chip list of software programming before SMT

Following chips must be programmed before SMT by ALL-11 or other tools.

Position Chip type Chip name Part number Software

description

1 U502 Flash EN25Q32B 13-EN25Q3-2BBEO main software SO-8

2 U702 E2PROM M24C32MN 13-M24C32-MNB Tcon software SO-8

Note:

1) The software for U502 and U702 can be program using ISP tool.

2) Every set has its unique HDCP key which is purchased from suppliers or HDCP

certification authority. Please check HDCP function in the process of production.

3) Once in a while, the software of main board may be upgraded. Please pay attention to

use the latest software before production.

Appendix:

1. Software upgrade through USB disk

1) Please ensure the software you are using has a correct file name
TCL_MS82_UPDATE.bin, then copy it to the root directory of a USB disk.

2) Insert the USB disk to the USB socket of the set for which you are
going to upgrade program.

3) Enter the Factory Menu (you can choose either a or b way below)
a. In the first place, press Menu button of remote
control, then select Contrast item of Picture
submenu. Finally, press 9, 7, 3, 5 consecutively.
b. When the Factory hotkey ite m of Factory Menu
is enabled (ON), press Return button of remote
control.

4) select USB UPDATE, press buttonof remote control, a pop menu
will appear prompting whether start upgradeor not. Press Yes to start upgrade,
press No to canel. Please wait patiently until the set restart automatically after

upgrade. Do not cut off the power supply during the process.

2. Check software version, release date and Project ID

After upgrading, sometimes you may not certain whether the new software has
been successfully updated or not. In this case, you can check the software version
and release date in Factory Main Menu to make sure the success of upgrading.
In addition, for the convenience of software management, many models of same
chassis may share a same software, but are allocated with different Project ID.
In another words, every model has its unique Project ID. Obviously, Both software
version and Project ID are highly critical to ensure the set work properly. Therefore,
after upgrading software,we suggest you check these information by following
method.

1) Enter the Factory Main Menu(you can choose either a or b way below
a In the first place, press Menu button of remote control, then select Contrast item
of Picture submenu. Finally, press 1, 9 5, 0 consecutively.
b. When the DESIGN HOTKEY item of Factory Main Menu is enabled (ON), press

Return button of remote control.

2) Check the version of software, release date displayed at the bottom of Factory
Main Menu. If the information is correct, you can ignore step C and D.

3) choose SERVICE MENU->PROJECT ID, choose corresponding Project ID number of

the product (Please refer to the description in BOM about Project ID number).

4) choose Factory Menu and press OK button of the remote. Next, select NVM RESET

and press and wait until prompt OK appears.

5) choose SHOP INIT and press

button of remote control to initialize the set.
Note: after step I (execute SHOP INIT), Hotel Menu will be disabled by default.
Therefore, if order requires hotel function, it is necessary to enable hotel function by
set

Factory Main Menu-> Service Menu->HOTEL ENABLE to ON.

6) restart the set.

3. FAQ

1) Why there is no picture after upgrading software or changing project ID?
It may be caused by fault of project ID. You can try below method to fix
the problem.
a. If the resolution of the panel of your set is 1366×768(HD panel), you can press

Menu, and 4976 of remote control in series after turning on.

b. If the resolution of the panel of your set is 1920×1080(FHD panel), you

can press Menu, and 4973 in series after turning on.
c. If you can see the picture at this time, please recheck the project ID again. If
the project ID is still wrong, correct it reference to above description.
