1 Safety Precautions
1.1.General Guidelines
1.When conducting repairs and servicing, do not attempt to modify the equipment, its parts or its materials.
2.When wiring units (with cables, flexible cables or lead wires) are supplied as repair parts and only one wire or some of the wires have been broken or disconnected, do not attempt to repair or re-wire the units. Replace the entire wiring unit instead.
3.When conducting repairs and servicing, do not twist the Fasten connectors but plug them straight in or unplug them straight out.
4.When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit.
5.After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed.
6.After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
1.2.Touch-Current Check
1.Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check.
2.Connect a measuring network for touch currents between each exposed metallic part on the set and a good earth ground such as a water pipe, as shown in Figure 1.
3.Use Leakage Current Tester (Simpson 228 or equivalent) to measure the potential across the measuring network.
4.Check each exposed metallic part, and measure the voltage at each point.
5.Reserve the AC plug in the AC outlet and repeat each of the above measure.
6.The potential at any point (TOUCH CURRENT) expressed as voltage U1 and U2, does not exceed the following values: For a. c.: U1 = 35 V (peak) and U2 = 0.35 V (peak);
For d. c.: U1 = 1.0 V,
Note:
The limit value of U2 = 0.35 V (peak) for a. c. and U1 = 1.0 V for d. c. correspond to the values 0.7 mA (peak) a. c. and 2.0 mA d. c.
The limit value U1 = 35 V (peak) for a. c. correspond to the value 70 mA (peak) a. c. for frequencies greater than 100 kHz.
7.In case a measurement is out of the limits specified, there is a possibility of a shock hazard, and the equipment should be repaired and rechecked before it is returned to the customer.

2 Warning
2.1.Prevention of Electrostatic Discharge (ESD) to Electrostatically
Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor [chip] components. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge (ESD).
1.Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, which should be removed for potential shock reasons prior to applying power to the unit under test.
2.After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.
3.Use only a grounded-tip soldering iron to solder or unsolder ES devices.
4.Use only an anti-static solder removal device. Some solder removal devices not classified as [anti-static (ESD protected)] can generate electrical charge sufficient to damage ES devices.
5.Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.
6.Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material).
7.Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the chassis or circuit assembly into which the device will be installed.
Caution
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
8.Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise ham less motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficient to damage an ES device).

2.2.About lead free solder (PbF)
Note: Lead is listed as (Pb) in the periodic table of elements.
In the information below, Pb will refer to Lead solder, and PbF will refer to Lead Free Solder.
The Lead Free Solder used in our manufacturing process and discussed below is (Sn+Ag+Cu).
That is Tin (Sn), Silver (Ag) and Copper (Cu) although other types are available.
This model uses Pb Free solder in it's manufacture due to environmental conservation issues. For service and repair work, we'd suggest the use of Pb free solder as well, although Pb solder may be used.
PCBs manufactured using lead free solder will have the PbF within a leaf Symbol PbF stamped on the back of PCB.
Caution
•Pb free solder has a higher melting point than standard solder. Typically the melting point is 50 ~ 70 °F (30~40 °C) higher. Please use a high temperature soldering iron and set it to 700 ± 20 °F (370 ± 10 °C).
•Pb free solder will tend to splash when heated too high (about 1100 °F or 600 °C).
If you must use Pb solder, please completely remove all of the Pb free solder on the pins or solder area before applying Pb solder. If this is not practical, be sure to heat the Pb free solder until it melts, before applying Pb solder.
•After applying PbF solder to double layered boards, please check the component side for excess solder which may flow onto the opposite side. (see figure below)
Suggested Pb free solder
There are several kinds of Pb free solder available for purchase. This product uses Sn+Ag+Cu (tin, silver, copper) solder. However, Sn+Cu (tin, copper), Sn+Zn+Bi (tin, zinc, bismuth) solder can also be used.

5.1.Specification of KEY for CI Plus, DTCP-IP, WIDEVINE and One-to-One
5.1.1. |
General information: |
|
1. |
EEPROM (IC8902) for spare parts has the seed of KEY for each. |
|
2. |
The final KEY data will be generated by Peaks IC (IC8000) when SELF CHECK was done and are stored in both Peaks IC |
|
|
(IC8000) and EEPROM (IC8902). |
|
|
Three KEY are not generated for all models. |
|
|
The necessary KEY are only generated and stored depend on the feature of models. |
|
5.1.2. |
Replacement of ICs: |
|
When Peaks IC (IC8000) is replaced, EEPROM (IC8902) should be also replaced with new one the same time. When EEPROM (IC8902) is replaced, Peaks IC (IC8000) is not necessary to be replaced the same time.
After the replacement of IC, SELF CHECK should be done to generate the final KEY data.
How to SELF CHECK: While pressing [VOLUME ( - )] button on the main unit, press [MENU] button on the remote control for more than 3 seconds.
TV will be forced to the factory shipment setting after this SELF CHECK.

5.2.1.General information:
Digital TV programmes can be recorded in USB HDD.
A One-to-One key generated in A-board by SELF CHECK binds TV and USB-HDD for communication.
That key is only one key for them. If the key is difference, TV can not access USB-HDD.
Caution:
New key will be generated by following SELF CHECK and previous TV programmes recorded in USB HDD will not be viewed.
SELF CHECK: While pressing [VOLUME ( - )] button on the main unit, press [MENU] button on the remote control for more than 3 seconds.
