WARNINGS AND CAUTIONS - ENGLISH

CAUTION
These servicing instructions are for use by qualified service personnel only. To reduce the ri sk o f el ec tr ic s hoc k, d o not per for m any s er vic ing other than tha t co nt aine d in the o p er at ing inst r ucti o ns unless you are qualified to do so.
WARNING!!
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.
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.
SAFETY-RELATED COMPONENT WARNING!!
Components identified by shading and ! mark on the schematic diagrams, exploded views, and in the parts list are critical for safe operation. Replace these components with Sony parts 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 improper operation is suspected.

USE CAUTION WHEN HANDLING THE L CD PANEL
When repair ing t he LCD p a nel , b e sure you ar e gro und ed b y using a wrist b and . When repair ing t he LCD p a nel on the wall , the LCD panel must be secured us ing the 4 mounting holes on the re ar c ove r .
1) Do not press on 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 not leave the module in high temper ature s or in areas of high humidity for an extende d pe rio d of time.
4) Do not expose the LCD panel to direct sunlight.
5) Avoid contact with water. It may cause a short circuit within the module.
6) Always clean the LCD panel with a soft cloth material.
7) Use care when handling the wires or connectors of the inverter circuit. Damaging the wires may cause a short.
8) Protect the panel from ESD to avoid damaging the electronic circuit (C-MOS).
9)It is recommended not to exceed 1 hour of Power-On nor Burn-in period with LCD panel face down condition, in repair activity.
10)Disconnect the AC power when replacing the parts.(FFC cable etc.).

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 interboard wiring to ensure that no wires are “pinched” o r touching high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps, and mounting hardware have been replaced. Be absolutely certain that you have replaced all the insulators.
4. Look for unauthorize d replacement parts, particularly transistors, tha t were installed during a p revious repair. Point them out to the customer and recommend their replacement.
5. Look for parts which, though functi oni ng, show obvio us si gns o f de te ri o ra tio n. P o int them out to the custo mer a nd r e co mmend 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, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.
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 o r oscillosc ope (r.m.s. or peak reading) Stabilized power supply instrument and isolated voltage transformer: Use too much current capacity and isolated v oltage transform er 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 1). 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: Nom inal input v oltage (Description on Nameplate) # Measure the leakag e current between one phase conductor and neutral for term inal 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 w orst v alue of measurem ent must not exceed AC 350uA peak). Note: including AC adaptor, AC adaptor/DC operated unit combination
How to Find a Good Earth Ground
A cold-water pipe is a guaranteed earth ground; the cover-plate retaining screw on m ost AC outlet boxes is also at earth g round. 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. If a cold-water pipe is not accessible, connect a 60- to 100-watt trouble- light (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 B).

Attention: This photo is based on Sony criteria for appearing standing the
main unit after removing back cover and assembling the stand. But considering mech an ical design of Taurus models and normal service process, it is not recommended to keep main unit standing by this status
for repairin g/ t est ing at repair c en ter. Please pay attention for avoiding
possible scra t ch / d ef orm ation occurred.
Note: Remove rear cover, then assembl e the stand to main unit. This
will cause the stand with main unit fit closely, scratch or deformation may occurred easily on the stand or bezel deco.
