ELECTRICAL SPECIFICATIONS

Cautions regarding use in high and low temperature environments

When the unit is used in a low temperature space (e.g. room, ofce), the picture may leave trails or appear slightly delayed. This is not a malfunction, and the unit will recover when the temperature returns to normal. Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed to direct sunlight or near a heater, as this may cause the cabinet to deform and the LCD panel to malfunction.Storage temperature: 20C to +60C.



SAFETY NOTICEMany electrical and mechanical parts in LCD television have special safety-related characteristics.These characteristics are often not evident from visual inspection, nor can protection afforded by them be necessarily increased by using replacement components rated for higher voltage, wattage, etc.Replacement parts which have these special safety characteristics are identied in this manual; electrical components having such features are identied by .

For continued protection, replacement parts must be identical to those used in the original circuit.The use of a substitute replacement parts which do not have the same safety characteristics as the factory recommended replacement parts shown in this service manual, may create shock, re or other hazards.

CAUTION: FOR CONTINUED PROTECTION AGAINST A RISK OF FIRE REPLACE ONLY WITH SAME TYPE F701 (4A / 250 V)

IMPORTANT SERVICE SAFETY PRECAUTIONService work should be performed only by qualied service technicians who are thoroughly familiar with all safety checks and the servicing guidelines which follow:

WARNING1. For continued safety, no modication of any circuit should be attempted.2. Disconnect AC power before servicing.

BEFORE RETURNING THE RECEIVER (Fire & Shock Hazard)

Before returning the receiver to the user, perform the following safety checks:1. Inspect all lead dress to make certain that leads are not pinched, and check that hardware is not lodged between the chassis and other metal parts in the receiver.2. Inspect all protective devices such as non-metallic control knobs, insulation materials, cabinet backs, adjustment and compartment covers or shields, isolation resistor-capacitor networks, mechanical insulators, etc.3. To be sure that no shock hazard exists, check for leakage current in the following manner.

Plug the AC cord directly into a 220~240 volt AC outlet. (Do not use an isolation transformer for this test).Using two clip leads, connect a 1.5k ohm, 10 watt resistor paralleled by a 0.15F capacitor in series with all exposed metal cabinet parts and a known earth ground, such as electrical conduit or electrical ground connected to an earth ground.

A true RMS reading multimeter should be used for this test, especially where the equipment uses a switch mode power supply which may result in very non-sinusoidal leakage current.Connect the resistor connection to all exposed metal parts having a return to the chassis (antenna, metal cabinet, screw heads, knobs and control shafts, escutcheon, etc.) and measure the AC voltage drop across the resistor.

All checks must be repeated with the AC cord plug connection reversed. (If necessary, a nonpolarized adaptor plug must be used only for the purpose of completing these checks.)Any reading of 1.05V peak (this corresponds to 0.7 mA. peak AC.) or more is excessive and indicates a potential shock hazard which must be corrected before returning the monitor to the owner.

In the case of LC-37P70E, for the Inverter PWB Units the type used is nickel, so they are marked as LFn:

PRECAUTIONS FOR USING LEAD-FREE SOLDER

1 Employing lead-free solderALL PWB of this model employs lead-free solder. The LF symbol indicates lead-free solder, and is attached on the PWBs and service manuals. The alphabetical character following LF shows the type of lead-free solder.Example:

2 Using lead-free wire solder

When xing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder may cause damage or accident due to cracks.As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40C, we recommend you to use a dedicated soldering bit, if you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station or service branch in your area.

3 Soldering

As the melting point of lead-free solder (Sn-Ag-Cu) is about 220C which is higher than the conventional lead solder by 40C, and as it has poor solder wettability, you may be apt to keep the soldering bit in contact with the PWB for extended period of time. However, Since the land may be peeled off or the maximum heat-resistance temperature of parts may be exceeded, remove the bit from the PWB as soon as you conrm the steady soldering condition.Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on and off the power of the bit as required.If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every use of it.When the tip of the soldering bit is blackened during use, le it with steel wool or ne sandpaper.

Be careful when replacing parts with polarity indication on the PWB silk.

Lead-free wire solder for servicing.

e:

Indicates lead-free solder of tin, silver and copper.

L F a

Indicates lead-free solder of tin, silver and nickel.

SPECIAL NOTE FOR USERS IN THE U.K.The mains lead of this product is fitted with a non-rewireable (moulded) plug incorporating a 13A fuse. Shouldthe fuse need to be replaced, a BSI or ASTA approved BS 1362 fuse marked or ASA and of the same ratingas above, which is also indicated on the pin face of the plug, must be used.Always refit the fuse cover after replacing the fuse. Never use the plug without the fuse cover fitted.In the unlikely event of the socket outlet in your home not being compatible with the plug supplied, cut off themains plug and fit an appropriate type.

DANGER:The fuse from the cut-off plug should be removed and the cut-off plug destroyed immediately and disposed ofin a safe manner.Under no circumstances should the cut-off plug be inserted elsewhere into a 13A socket outlet, as a seriouselectric shock may occur.To fit an appropriate plug to the mains lead, follow the instructions below:

IMPORTANT:The wires in the mains lead are coloured in accordance with the following code:

Blue: NeutralBrown: Live

As the colours of the wires in the mains lead of this product may not correspond with the coloured markingsidentifying the terminals in your plug, proceed as follows: The wire which is coloured blue must be connected to the plug terminal which is marked N or coloured black. The wire which is coloured brown must be connected to the plug terminal which is marked L or coloured red.Ensure that neither the brown nor the blue wire is connected to the earth terminal in your three-pin plug.Before replacing the plug cover make sure that: If the new fitted plug contains a fuse, its value is the same as that removed from the cut-off plug. The cord grip is clamped over the sheath of the mains lead, and not simply over the lead wires.IF YOU HAVE ANY DOUBT, CONSULT A QUALIFIED ELECTRICIAN.

The adjustment values are set to their optimum at the factory before shipping. If by any chance a value should become im-proper or a readjustment is required due to part replacement, make an adjustment according to the following procedure.

1. Entering and exiting the adjustment process mode

1- Unplug the AC power cord of TV set to force power off.2- While holding down the VOL () and INPUT keys on the set at once, plug in the AC power cord to turn on the set. The letter K appears on the screen. (Factory mode)3- Next, hold down the VOL () and P ( V ) keys on the set at once. Multiple lines of orange characters appearing on the screen indicate that the set is now in the adjustment process mode. If you fail to enter the adjustment process mode (the display is the same as normal start up), retry the procedure.4- To exit the adjustment process mode after the adjustment is done, unplug the AC power cord to force off the power. (When the power is turned off by the remote controller, unplug also the AC power cord and wait for 10 seconds before plug it in again.)5- To remove K mode, just repeat steps 1 and 2.

Condition of the inspection: Backlight: MAX (+8) [DYNAMIC] Colorimeter at screen centreAdjustment reference device: Minolta CA-210

Tolerance adjustment spec. 0.004, Inspection spec. : 0.006 (GAMMA 1)Tolerance adjustment spec. 0.002, Inspection spec. : 0.004 (GAMMA 2...6)

Adjustment: Check that the values on page 7/11 of process adjustment are set as below. If not, change them ac-cordingly.

M GAMMA IN 1 160 M GAMMA IN 2 320M GAMMA IN 3 480 M GAMMA IN 4 640M GAMMA IN 5 800 M GAMMA IN 6 960

1- Display the current adjustment status at point 6. (Page 9/11 of process adjustment)The pattern for checking the adjustment status is toggled by pressing the 6 button on the remote control. (Normal OSD display -> 6 -> pattern for check (OSD disappears) -> 6 -> normal OSD display -> )

2- Read the value of the luminance meter.

3- Change M GAMMA R6/M GAMMA B6 (adjustment offset value) on page 9/11 of process adjustment so that the values of the luminance meter approach x = 0.272 and y = 0.277.(Basically, G is not changed. If adjustment fails only with R and B, then G should be reduced. In this case, the weaker of R and B must be xed.)

4- If G is changed in step 3, change the values of M GAMMA G1 - M GAMMA G5 on pages 8/11 and 9/11 of process adjustment as follows. When not changed, go to step 5.

Offset value of M GAMMA G1 = (Offset value of M GAMMA G6)*(160/960) Offset value of M GAMMA G2 = (Offset value of M GAMMA G6)*(320/960)

Offset value of M GAMMA G3 = (Offset value of M GAMMA G6)*(480/960)Offset value of M GAMMA G4 = (Offset value of M GAMMA G6)*(640/960)Offset value of M GAMMA G5 = (Offset value of M GAMMA G6)*(800/960)
