Whenever a TV Mainboard is replaced, the correct TV ModelandSerial number must be
reinserted into memory.
This is a MANDATORY procedure thateach service center must apply.
Please refer to the chapter of ADJUSTMENT in this service manual to findouthow to set the
modelnumberand serial number in service mode.
1-2-1. Caution Handling of LCDPanel
When repairing the LCDPanel, make sure you are grounded with a wrist band.
When repairing the LCDPanel on the wall, the panel must be secured using the 4 mounting
holes on the rear cover.
1) Do not press the panel or frame edge to avoid the risk of electric shock.
2) Do not scratch or press on the panel with any sharp objects.
3) Do notleave the moduleinhigh temperature or in areas of high humidity for an
extendedperiod of time.
4) Do not expose the LCDpanel to direct sunlight.
5) Avoid contact with water. It may cause short circuit within the module.
6)Disconnect the AC power when replacing the backlight (CCFL)or inverter circuit. (High
voltage occurs at the inverter circuit at 650Vrms)
7) Always clean the LCDpanel with a soft cloth material.
8) Use care whenhandling the wires or connectors of the inverter circuit. Damaging the wires
may cause a short circuit.
9) Protect the panel from ESD to avoid damaging the electronic circuit (C-MOS).
1-1. WarningsandCaution
1) CAUTION :These servicing instructions are for use by qualified service personnel
only.
2) To reduce the risk of electric shock, do notperform any servicing other than that contained
in the operatinginstructionsunless you are qualified to do so.
3) WARNING!!:An isolation transformer should be used duringany 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 could be in the neutral of the mains supply. When replacing the fuse,
the mains shall be disconnected for de-energize the phase conductors.
(*Except AC ADAPTOR, Because it doesnot carry out replacing an internal fuse.)
4) CARRYING THE TV : Be sure to follow these guidelines to protect your property and
avoid causing seriousinjury :
•Carry the TV with an adequate number of people; larger size TVs require two or more
people.
•Correct handplacement while carrying the TV is very important for safety and to
avoiddamages.
5) SAFETY-RELATED COMPONENT WARNING!! : Components identified by shadingand
! mark on the exploded views, and in the parts list are critical for safe operation. Replace
these components with Sonyparts whose part numbers appear as shown in this manual
or in supplements published by Sony. Circuit adjustments that are critical for safe
operation are identified in this manual.Follow these procedures whenever critical
components are replaced or improperoperation is suspected.
6) IMPORTANT REMINDER FOR TV MAINBOARD REPLACEMENT :
It is mandatory for service centers to confirm the TV‘s system information after each repair
carriedout with Mainboard replacement.

1-5. 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 pinchedor contact high-
wattage resistors.
3)Check all control knobs, shields, covers, ground strapsand mounting hardware have
been replaced. Be absolutely certain you have replaced all the insulators.
4) Look for unauthorized replacement parts, particularly transistors that
were installed during aprevious repair.Point them out to the customer and recommend their
replacement.
5) Look for parts which, though functioning show obvious signs of deterioration.Point them
out to the customer and recommend their 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.
1-6. 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 volt meter: Input resistance > 1 Mohm, Input capacitance < 200 pF,
Frequency range: 15 Hz –1MHz . Refer Figure 2. Isolated type volt -meter (FLUKE 8921A
etc *1)
1-4. Caution 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 shouldnot contact to water.

# 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-pinplug): for each terminal, the worst valueof measurement must
not exceed AC 350uA peak).

1-8. Lead Free Information
The circuitboards used in these modelshave been processed using
Lead Free Solder. The boards are identified by the LF logo located
close to the board designation.
Figure 4: LF Logo Figure 5: LF logo on circuit board
1-7. Howto Find a GoodEarth Ground
1)A cold-water pipe is a guaranteedearth ground; the cover-plate retaining screw on most
AC outletboxes is also at earth ground.
2)If the retaining screw is to be used as yourearth 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 trouble- light (not a neonlamp)
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).
Figure 3. Checking for earth ground.
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.

The units in this manual contain a self-diagnostic function. If an error occurs, the Smart Core Red LED willautomaticallybegin to flash. The number of times the LED flashes translates to a probable
source of the problem.
Adefinition of the Smart Core Red LED flash indicators is listed in the instruction manual for the user’s knowledge and reference.
If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.
DIAGNOSTIC TEST INDICATORS
Whenan error occurs, the Smart Core Red LED will flash aset number of times to indicate the possible cause of the problem. If there is more than one error, the LED will identify the first of
the problem areas.
Result for all of the following diagnostic items are displayed on screen. If the screen displays a “0”, no error has occurred .
