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 Ele ctrical Code, NFPA No. 70-1975, provides information with respect to proper grounding of the mast and supporting structure, 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 Ar ticle 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 shouldnot 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.

has to be performed into subdued lighted room after at least 60min of warm-up in order to avoid any

temperature drift influence (colorimetry vs time).

4.1 Pre-Conditions and Power Supply Check

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

and make sure that no serious issue or mistake can destroy the board. For example, the output of DC/DC

and LDO should not be shorted to ground.

Supply a suited voltage and power-on, then check the voltage according to the relevant block diagram,

circuit diagram and voltage spec, the error should be less than 5%, for example, the voltage for main chip

(+3V3, +2.5V, VDDC1V15, 1V5_DDR, etc.), the voltage for TUNER (TU_3V3), the voltage for amplifier

(AMP_VCC), etc.

4.2 Project ID Modification

There are different ID stored in the EMMC depending on different Panels settings and Models features,

but there’s only one key branching Project ID able to ensure normal display. And when you power on the

TV set, you should make sure the Project ID is accord with the BOM description. If not, you need to

modify the ID. There is two methods to modify the ID:
