IMPORTANT SAFETY INSTRUCTIONS

CAUTION:

Read all of these instructions. Sa ve these instructions for later use . Follo w all Warnings and
Instructions marked on the audio equipment.

1. Read Instructions-All the safety and operatinginstructionsshouldbe read before the productis operated.

2. Retain Instructions- The safety and operating instructions should be retained for future reference.

3. Heed Warnings- All warnings on the product and in the operating instructions should be adhered to.

4. Follow Instructions- All operating and use instructions should be followed.

FOR YOUR PERSONAL SAFETY

1. When the power cord or plug is damaged or frayed, unplug this television set from the wall outlet and refer servicing to
qualified service personnel.

2. Do not overload wall outlets and extension cords as this can result in fire or electric shock.

3. Do not allow anything to rest on or roll over the power cord, and do not place the TV where power cord is subject to
traffic or abuse. This may result in a shock or fire hazard.

4. Do not attempt to service this television set yourself as opening or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to qualified service personnel.

5. Never push objects of any kind into this television set through cabinet slots as they may touch dangerous voltage
points or short out parts that could result in a fire or electric shock. Never spill liquid of any kind on the television set.

6. If the television set has been dropped or the cabinet has been damaged, unplug this television set from the wall outlet
and refer servicing to qualified service personnel.

7. If liquid has been spilled into the television set, unplug this television set from the wall outlet and refer servicing to
qualified service personnel.

8. Do not subject your television set to impact of any kind. Be particularly careful not to damage the picture tube surface.

9. Unplug this television set from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a
damp cloth for cleaning.

10.1. Do not place this television set on an unstable cart, stand, or table. The television set may fall, causing serious injury
to a child or an adult, and serious damage to the appliance . Use only with a cart or stand recommended by the
manufacturer, or sold with the television set. Wall or shelf mounting should follow the manufacturer s instructions, and
should use a mounting kit approved by the manufacturer.

10.2. An appliance and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces
may cause the appliance and car t combination to overturn.

PROTECTION AND LOCATION OF YOUR SET

11. Do not use this television set near water ... for example, near a bathtub, washbowl, kitchen sink, or laundry tub, in a
wet basement, or near a swimming pool, etc.
Never expose the set to rain or water. If the set has been exposed to rain or water, unplug the set from the wall
outlet and refer servicing to qualified service personnel.

12. Choose a place where light (artificial or sunlight) does not shine directly on the screen.

13. Avoid dusty places, since piling up of dust inside TV chassis may cause failure of the set when high humidity persists.

14. The set has slots, or openings in the cabinet for ventilation purposes, to provide reliable operation of the receiver, to

protect it from overheating. These openings must not be blocked or covered.

Never cover the slots or openings with cloth or other material.
Never block the bottom ventilation slots of the set by placing it on a bed, sofa, rug, etc.
Never place the set near or over a radiator or heat register.
Never place the set in enclosure, unless proper ventilation is provided.

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.

OPERATION OF YOUR SET

18.

This television set should be operated only from the type of power source indicated on the marking label.If you are not
sure of the type of power supply at your home, consult your television dealer or local power company. For television
sets designed to operate from battery power, refer to the operating instructions.

19. If the television set does not operate normally by following the operating instructions, unplug this television set from the
wall outlet and refer servicing to qualifiedservice personnel. Adjust only those controls that are covered in the operating
instructions as improper adjustment of other controls may result in damage and will often require extensive work by a
qualified technician to restore the television set to normal operation.

20. When going on a holiday : If your television set is to remain unused for a period of time, for instance, when you go on
a holiday, turn the television set and unplug the television set from the wall outlet.

off

IF THE SET DOES NOT OPERATE PROPERLY

21. If you are unable to restore normaloperationby followingthedetailedprocedurein your operating instructions,
do not attempt any further adjustment. Unplug the set and call your dealer or service technician.

22. Whenever the television set is damaged or fails, or a distinct change in performance indicates a need for
service, unplug the set and have it checked by a professional service technician.

23. It is normal for some TV sets to make occasional snapping or popping sounds, particularly when being
turned on or off. If the snapping or popping is continuous or frequent, unplug the set and consult your

1. Electrical Assembly Alignment

1.1. Preconditions – DC/DC Check

Before power on, please check the board according to the relevant block diagram and circuit

diagram, and make sure

that no serious error should destroy the board. For example,the output
of DC/DC and LDO should not shorted to ground.
Supply a suited voltage and power on , then check the voltage according to the relevant block
diagram , circuit diagram and volt
voltage for main chip(AVDD3V3, DVDD3V3,

age spec . the error should less than 5% .For example, the

VCCK,etc.), the voltage for DDR (DDRV) , the

voltage for amplifier(AUDIO_PWR),etc. Only the standby voltage is necessary if there is no
software in the flash .

1.2. SW download

Download the latest release MT8223_SW into the flash using MTK SW tool. See Appendixo

“How to download FLASH SW”. Or upgrade the SW from USB port See Appendixp” Ho

w to

upgrade FLASH SW from USB”.

1.3. Panel ID check and modify

There is different ID stored in the NVM depended on different Panels. Modify it with Hyper

terminal if the initial ID or a wrong ID make the set can not display clearly. See Appendixr

. It can

be checked and modified in Factory menu->Feature->Panel ID if the set can display clearly .

The set should be restart if the panel ID is changed .

1.4. Functional Test

Once the boards (chassis, KB, IR, PSU…) and the panel are well interconnected, connect all
external generator devices to relevant input
