SAFETY NOTES

Warnings and Caution.

1. 
   These servicing instructions are for use by qualified service personnel only.
2. To reduce the risk of electric shock, do not perform any servicing other than that stated in the operating instructions unless you are qualified to do so.
3. 
   An isolation transformer should be used during any service to avoid possible shock hazard, because of live chassis. The chassis of this receiver is directly connected to the ac power line. The replaceable fuse should be in the neutral of the mains supply. When replacing the fuse, the mains must be disconnected to de-energize the phase conductors. (*Except AC ADAPTOR, because it does not carry out replacing an internal fuse.)
4. CARRYING THE TV: be sure to follow these guidelines to protect your property and avoid causing serious injury:

• Carry the TV with an adequate number of people; larger size TVs require two or more people.
• Correct hand placement while carrying the TV is very important for safety and to avoid damages.

Panel refresh
Panel refresh will automatically run to adjust the uniformity of the TV screen after it has been in use for long periods. Panel refresh can also be performed manually and should only be used if image retention is very noticeable, or you see the following message: [Panel refresh did not finish...]

• The Panel refresh function may affect the panel. As a reference, perform the Panel refresh only once a year, do not perform it more than once a year as it may affect the usable life of the panel.
• Panel refresh takes about one hour to complete.
• A white line may be displayed on the screen during the Panel refresh, this is not a malfunction of the TV.
• Panel refresh will only work when the room temperature is between 10-40ºC.

Pixel shift.
Automatically moves the image on the screen to prevent image retention.

Another feature.
The screen brightness is automatically reduced when displaying still images, clocks, bright colors or logos etc.

Caution_for_Board_handling.

The following problems will occur due to handling of the IC mounted on the board

• Solder crack due to substrate handling (stress).
• IC breakdown due to static electricity (ESD).

When repairing the TV at the customer's home or service station or Repair of defect board, please pay attention to the handling of the board.

Substrate that needs attention for handling:

• Main Board ( B** Board )
• Backend Board ( D** Board )

※ Things to prepare in advance.
E SD wris t-strap.

※
ESD wrist-strap to be checked daily.
Use Multi-meter to make sure resistance of ESD wrist-strap is OK.
(R=750K Ohms to 35Mega Ohms)

ESD cushion / sheet
Please use a bag containing the board or a special seat

3. Handle with care. Do not swing
   
4. Regardless of Good board or Defective board, always put it on ESD cushion / sheet slowly.
   
5. Do not stack up
   

2. Caution for Board handling (ESD).Be sure to observe the following contents
   1. When take off Rear-Cover, do not touch to board
      
   2. Use ESD wrist-strap
      

3. When holding board, do not hit or touch to Plastic part(s) After take defective board out from TV, put it into ESD bag.
   
4. Do not place on floor mat/carpet direct. And, always put it on ESD cushion
   

About the Lithium Battery.

1. Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.
2. Outer case broken battery should not contact to water.

Safety Check-Out
After correcting the original service problem, perform the following safety checks before releasing the set to the customer:-

1. Check the area of your repair for unsoldered or poorly soldered connections. Check the entire board surface for solder splashes and bridges.
2. Check the inter board wiring to ensure that no wires are pinched or contact high-wattage resistors.
3. Check all control knobs, shields, covers, ground straps and mounting hardware have been replaced. Be certain you have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly transistors that were installed during a previous repair. Point them out to the customer and recommend them replacement.
5. Look for parts which show obvious signs of deterioration even though functioning. Point them to the customer and recommend for replacement.
6. Check the line cords for cracks and abrasion. Recommend the replacement of any such line cord to the customer.
7. Check the antenna terminals, metal trim, metalized knobs, screws and all other exposed metal parts for AC leakage. Check leakage test as described next.
8. For safety reasons, repairing the Power board and/or Inverter board is prohibited.

Leakage Test.
(To protect electric shock when customer touch the terminal.). Leakage current can be measured by V: Voltmeter or oscilloscope (r.m.s or peak reading).
Stabilized power supply instrument and isolated voltage transformer:
Use too much current capacity and isolated voltage transformer does not need to use stabilized power supply equipment. Specification of RMS voltmeter: Input resistance > 1 Mohm, Input capacitance < 200 pF, Frequency range: 15 Hz – 1MHz. Refer Figure 2. Isolated type volt - meter (FLUKE 8921A etc *1). *1 Not use FLUKE 8920A that connected to protective earth by diode. # Leakage current of measurement instrument is less than 10μArms when under test equipment AC plug is opened. # Set up the following condition and turn on the set. Applied voltage: Nominal input voltage (Description on Nameplate). # Measure the leakage current between one phase conductor and neutral for terminal A and terminal B. Read rms value, and then calculate to peak value PEAK VALUE =√2 RMS VALUE. Comply with the following requirement. Class II equipment (2-pin plug): for each terminal, the worst value of measurement must not exceed AC 350uA peak).
Note: including AC adaptor, AC adaptor/DC operated unit combination.

How to Find a Good Earth Ground.

1. A cold-water pipe is a guaranteed earth ground; the cover-plate retaining screw on most AC outlet boxes is also at earth ground.
2. If the retaining screw is to be used as your earth ground, verify that it is at ground by measuring the resistance between it and a cold-water pipe with an ohmmeter. The reading should be zero ohms.
3. If a cold-water pipe is not accessible, connect a 60- to 100-watt troublelight (not a neon lamp) between the hot side of the receptacle and the retaining screw. Try both slots, if necessary, to locate the hot side on the line; the lamp should light at normal brilliance if the screw is at ground potential (see Figure 3).
   

Lead Free Information
The circuit boards used in these models have been processed using Lead Free Solder. The boards are identified by the LF logo located close to the board designation.

The servicing of these boards requires special precautions. It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints.
