SERVICING NOTICES ON CHECKING
1. KEEP THE NOTICES
As for the places which need special attentions, they are indicated with the labels or seals on the cabinet, chassis and parts. Make sure to keep the indications and notices in the operation manual.
3. USE THE DESIGNATED PARTS
2. AVOID AN ELECTRIC SHOCK
There is a high voltage part inside. Avoid an electric shock while the electric current is flowing.
The parts in this equipment have the specific characters of incombustibility and withstand voltage for safety. Therefore, the part which is replaced should be used the part which has the same character. Especially as to the important parts for safety which is indicated in the circuit diagram or the table of parts as a mark, the designated parts must be used.
5. PUT PARTS AND WIRES IN THE ORIGINAL POSITION AFTER ASSEMBLING OR WIRING
There are parts which use the insulation material such as a tube or tape for safety, or which are assembled in the condition that these do not contact with the printed board. The inside wiring is designed not to get closer to the pyrogenic parts and high voltage parts. Therefore, put these parts in the original positions.
PERFORM A SAFETY CHECK AFTER SERVICING
6.
Confirm that the screws, parts and wiring which were removed in order to service are put in the original positions, or whether there are the portions which are deteriorated around the serviced places serviced or not. Check the insulation between the antenna terminal or external metal and the AC cord plug blades. And be sure the safety of that.
(INSULATION CHECK PROCEDURE)
1.
2.
3.
4.
Unplug the plug from the AC outlet. Remove the antenna terminal on TV and turn on the TV. Insulation resistance between the cord plug terminals and the eternal exposure metal [Note 2] should be more than 1M ohm by using the 500V insulation resistance meter [Note 1]. If the insulation resistance is less than 1M ohm, the inspection repair should be required.
[Note 1]
If you have not the 500V insulation resistance meter, use a Tester.
[Note 2]
External exposure metal: Antenna terminal
A1-1
4. BE CAREFUL WITH THE
LCD PANEL
Avoid a shock to the panel while servicing. Take enough care to deal with it.
When you exchange IC and Transistor with a heat sink, apply silicon grease (YG6260M) on the contact section of the heat sink. Before applying new silicon grease, remove all the old silicon grease. (Old grease may cause damage to the IC and Transistor).
IMPORTANT
Please include the following informations when you order parts. (Particularly the VERSION LETTER.)
1. MODEL NUMBER and VERSION LETTER The MODEL NUMBER can be found on the back of each product and the VERSION LETTER can be
found at the end of the SERIAL NUMBER.
2. PART NO. and DESCRIPTION You can find it in your SERVICE MANUAL.

PCBs (manufactured) using lead free solder will have a PbF printing on the PCB. (Please refer to figures.)
Caution:
Pb free solder has a higher melting point than standard solder; Typically the melting point is 86°F~104°F(30°C~40°C) higher. Please use a soldering iron with temperature control and adjust it to 650°F ± 20°F (350°C ± 10°C). In case of using high temperature soldering iron, please be careful not to heat too long. Pb free solder will tend to splash when heated too high (about 1100°F/ 600°C). All products with the printed circuit board with PbF printing must be serviced with lead free solder. When soldering or unsoldering, completely remove all of the solder from the pins or solder area, and be sure to heat the soldering points with the lead free solder until it melts sufficiently.
Distinction of PbF PCB:
Recommendations
Recommended lead free solder composition is Sn-3.0Ag-0.5Cu.

Put Masking Tape (cotton tape) around the Flat Package IC to protect other parts from any damage.
(Refer to Fig. 2-1.)
1.
Fig. 2-1
NOTE
REMOVAL AND INSTALLATION OF FLAT PACKAGE IC
Some ICs on the PCB are affixed with glue, so be careful not to break or damage the foil of each IC leads or solder lands under the IC when removing it.
NOTE
Masking is carried out on all the parts located within 10 mm distance from IC leads.
Blower type IC desoldering machine
IC
Heat the IC leads using a blower type IC desoldering machine. (Refer to Fig. 2-2.)
2.
Fig. 2-2
NOTE
Do not rotate or move the IC back and forth , until IC can move back and forth easily after desoldering the leads completely.
When IC starts moving back and forth easily after desoldering completely, pickup the corner of the IC using tweezers and remove the IC by moving with the IC desoldering machine. (Refer to Fig. 2-3.)

Thin-tip Soldering Iron
NOTE
When the IC leads are bent during soldering and/or repairing, do not repair the bending of leads. If the bending of leads are repaired, the pattern may be damaged. So, always be sure to replace the IC in this case.
Finally, confirm the soldering status on four sides of the IC using a magnifying glass. Confirm that no abnormality is found on the soldering position and installation position of the parts around the IC. If some abnormality is found, correct by resoldering.

Solder temporarily
Soldering Iron
INSTALLATION
Take care of the polarity of new IC and then install the new IC fitting on the printed circuit pattern. Then solder each lead on the diagonal positions of IC temporarily.

ADDRESS is now selected and should "blink". Using the UP/DOWN buton on the remote, step through the ADDRESS until required ADDRESS to be changed is reached. Press LEFT/RIGHT button to select DATA. When DATA is selected, it will "blink". Again, step through the DATA using UP/DOWN button until required DATA value has been selected. Pressing LEFT/RIGHT button will take you back to ADDRESS for further selection if necessary. Repeat steps 4 to 6 until all data has been checked. When satisfied correct DATA has been entered, turn POWER off (return to STANDBY MODE) to finish DATA input.
After the data input, set to the initializing of shipping.
Turn on the Power. Set the VOLUME to minimum. Press both VOL. DOWN button on the set and Channel button (1) on the remote control for more than 2 seconds. After the finishing of the initializing of shipping, the unit will turn off automatically.

CAUTION
Use an isolation transformer when performing any service on this chassis. When removing a PCB or related component, after unfastening or changing a wire, be sure to put the wire back in its original position. When you exchange IC and Transistor with a heat sink, apply silicon grease (YG6260M) on the contact section of the heat sink. Before applying new silicon grease, remove all the old silicon grease. (Old grease may cause damages to the IC and Transistor).
