WARNINGS AND CAUTION S - ENGLISH

CAUTION

These servicing instructions are for use by qualified service personnel only. To reduce the ri sk o f ele ct ri c sho c k, d o not perfo r m a ny se rvi ci ng other than tha t c ont ai ned in t he o p er at ing ins tr uct io 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 serio us 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 opera tion are identified in this manual. Follow these procedures whenever critical components are replaced or improper operation is suspected.

CAUTION ABOUT THE LITHIUM BATTERY

• Danger of explosion if battery is incorrectly replaced. Replace o nly with the same or equivalent type.

• Outer case broken battery should not contact to water.

WARNINGS AND CAUTION S - FRENCH

ATTENTION!!

Ces instructions de service sont à l’usage du personnel de service qualifi é seulement. Pour prévenir le risque de choc électrique, ne pas faire l’entretien autre que celui contenu dans le Mode d’emploi à moins que vous soyez qualifi é faire ainsi.

WARNING!!

Afi n d’eviter tout risque d’electrocution provenant d’un chássis sous tension, un transformateur d’isolement doit etre utilisé lors de tout dépannage. Le chássis de ce récepteur est directement raccordé à l’alimentation du secteur.

POUR TRANSPORTER LE TÉLÉVISEUR

Tenez compte de ce qui suit pendant l’installation du téléviseur :

• Débranchez tous les câbles avant de transporter le téléviseur.

• Transportez le téléviseur avec le nombre de personnes approprié ; un téléviseur de grande taille doit être transporté par au moins deux personnes.

• Lors du transport du téléviseur, l’emplacement de s mains est très important pour votre sécurité, ainsi que pour éviter de causer des dommages.

ALERTE!!

Afi n d’eviter tout risque d’electrocution provenant d’un c hassis sous tensio n, un transformateur d’isolement doit etre utilise lors de tout depannage. Le chassis de ce recepteur est directement raccorde a l’alimentation du secteur.

ATTENTION AUX COMPOSANTS RELATIFS A LA SECURITE!!

Les composants identifi es par une trame et par une marque sur les schemas de principe, les vues explosees et les listes de pieces sont d’une importance critique pour la securite du fonctionnement. Ne les remplacer que par des composants Sony dont le numero de piece est indique dans le present manuel ou dans des supplements publies par Sony. Les reglages de circuit dont l’importance est critique pour la securite du fonctionnement sont identifi es dans le present manuel. Suivre ces procedures lors de chaque remplacement de composants critiques, ou lorsqu’un mauvais fonctionnement suspecte.

USE CAUTION WHEN HANDLING T HE LCD PANEL

When repa ir ing the LCD p a nel, b e sure you ar e gro und ed b y using a wrist b and . When repa ir ing the LCD p a nel o n the wall, the LCD panel must b e sec ur ed using 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 atures or in areas of high humidity for an ext ended period 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) 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 LCD panel with a soft cloth material.

8) Use care when handling the wires or connectors of the inverter circuit. Damaging the wires may cause a short.

9) Protect the panel from ESD to avoid damaging the electronic circuit (C-MOS).

10) It is recommended not to exceed 1 hour of Power-On nor Burn-in p erio d with LCD panel face d own condition, in repair activity.

WARNINGS AND C AUT IO NS

KDL-50FA95C, 97C

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” or touching high-wattage resistors.

3. Check that all control knobs, shields, covers, ground straps, and mounting hardware have been rep laced. Be absolutely certain that 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 their replac ement.

5. Look for part s which, though functioni ng, show obvi ous signs o f d et er io r ati o n. P o int them out to the cust o mer a nd re c ommend 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 Inver te r board is prohibited.

KDL-50FA95C, 97C

7 7

Leakage Test

The AC leakage from any exposed metal part to earth ground and from all exposed m etal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes). Leakage current can be m easured by any one of three m ethod s.

1. A commercial leakag e tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers’ instructions to use these instructions.

2. A battery-operated AC milliampmeter. The Data Precision 245 digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a VOM or battery -operated AC voltmeter. The “limit” indicati on is 0.75 V, so analog meters must have an accurate low voltage scale. The Simpson’s 250 and Sanwa SH-63TRD are examples of passiv e VOMs that are suitable. N early all battery-operated digital multimeters that have a 2 VAC range are suitable (see Figure A).

How to Find a Good Earth Ground

A cold-water pipe is a guaranteed earth ground; the cover-plate retaining screw on most AC outlet boxes is also at earth ground. 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).

OUTLINE OF SELF DIAGNOSIS FUNCTION

The units in this manual c ontain a self-diagnostic function. If an error occ urs, the ST ANDBY LED will automatically b egin to flash. The number of times the LED flashes translates to a probable source of the problem. A definition of the STANDBY LED flash indicators is listed in the instruction manual for the user’s knowledge and r eference. 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.
