WARNING AND CAUTIONS

A

CAUTION

These servicing instructions are for use by qualiﬁed service personnel only To reduce the risk of electric shock, do not perform any servicing other than that contained in the operating instructions unless you are qualiﬁed to do so.

WARNING!!

n 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.

!

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.

ATTENTION!!

Ces instructions de service sont à l’usage du personnel de service qualiﬁé 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 qualiﬁé faire ainsi.

ﬁn 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

!

ATTENTION AUX COMPOSANTS RELATIFS A LA SECURITE!!

Les composants identiﬁes 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 identiﬁes dans le present manuel. Suivre ces procedures lors de chaque remplacement de composants critiques, ou lorsqu’un mauvais fonctionnement suspecte.

KDE55XBR950 (UC) 3

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 contact 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 unauthorized replacement parts, particularly transistors, that were installed during a previous 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, “metallized” knobs, screws, and all other exposed metal parts for AC Leakage. Check leakage as described right.

LEAKAGE TEST

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

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

2. A battery-operated AC milliammeter. 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” indication is 0.75 V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOMs that are suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable. (See Fig. A)

WARNING!!

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.

AVERTISSEMENT!! ATTENTION AUX COMPOSANTS RELATIFS À LA SÉCURITÉ!! LES COMPOSANTS IDENTIFIÉS PAR UNE TRAME ET UNE MARQUE ! SONT CRITIQUES POUR LA SÉCURITÉ. NE LES REMPLACER QUE PAR UNE PIÈCE PORTANT LE NUMÉRO SPECIFIÉ. LES RÉGLAGES DE CIRCUIT DONT L’IMPORTANCE EST CRITIQUE POUR LA SÉCURITÉ DU FONCTIONNEMENT SONT IDENTIFIÉS DANS LE PRÉSENT MANUEL. SUIVRE CES PROCÉDURES LORS DE CHAQUE REMPLACEMENT DE COMPOSANTS CRITIQUES, OU LORSQU’UN MAUVAIS FONCTIONNEMENT EST SUSPECTÉ.

DIAGNOSIS

(Reliability Self Diagnostic Display Specifications for MEDIA RECEIVER)

Error message by blink of LED

1) If abnormalities are detected inside a unit,

“POWER” LED blinks in RED automatically.

A failure part can be expected by the number of times of blink of LED. When two failures occur, the failure item generated previously is detected. When failure occurs simultaneously, an item with little number of times of blink is detected.

In other than “Fan Error”, the unit is in standby state and blink LED at intervals of regulation. In Fan Error, the unit is in a standby state after display for 1 minute about the message of “Fan problem — Powering down”

about 3s

OFF

every about 0.3s

2) In the following case, POWER LED of Media Receiver Box blinks at a fixed interval in ORANGE

• When the cable which connects between Media Receiver Box and Panel Display has fallen out.

• When the AC code for Panel Display has fallen out.

In the following case, POWER LED of Panel Display blinks at a fixed interval in ORANGE

• When the cable which connects between Media Receiver Box and Panel Display has fallen out.

• When the AC code for Media Receiver Box has fallen out.

3) The example which judges whether it is failure

• POWER LED of Media Receiver Box: Blink 9 times in RED, and of Panel Display blink,

and No picture or Power circuit does not work

→ Large possibility that Panel Display is out of order.

• When turn on Media Receiver Box, and NO LED of Box shine → Large possibility that Media Receiver

Box is out of order.

• When NO Blue LED of Box shine → Large possibility that Media Receiver Box is out of order.

Check SET5V or IIC line on H1 board.

• When turn on Media Receiver Box, and Fan does not work

→ Large possibility that Media Receiver Box is out of order

KDE55XBR950 (UC) 5

The screen display of self-diagnostic history

The case of failure which cannot check condition of “Power supply is sometimes shut off ”, or “Picture sometimes disappearing” etc, we can check on the screen whether failure has occurred (whether the detection circuit has operated) before.

The display method of diagnostic result

From “STANDBY” state, push Remote Control quickly “DISPLAY”, “CH5”, “VOL-”, “POWER” in order.

* “0” means no abnormalities, and it means that “1” had one detection or more. * 101:WDT ;LED dose not blink. “0” means the number of times of detection.
