DIRECTLY CONNECTED TO THE POWER LINE.
SAFETY-RELATED COMPONENT WARNING !!
COMPONENTS IDENTIFIED BY SHADING AND MARKED 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.
ATTENTION
APRES AVOIR DECONNECTE LE CAP DE’LANODE,
COURT-CIRCUITER L’ANODE DU TUBE CATHODIQUE ET
CELUI DE L’ANODE DU CAP AU CHASSIS METALLIQUE DE
L’APPAREIL, OU AU COUCHE DE CARBONE PEINTE SUR LE
TUBE CATHODIQUE OU AU BLINDAGE DU TUBE
CATHODIQUE.
ATTENTION !!
AFIN D’EVITER TOUT RISQUE D’ELECTROCUTION
PROVENANT D’UN CHÁSSIS SOUS TENTION, UN
TRANSFORMATEUR D’ISOLEMENT DOIT ETRE UTILISÈ LORS
DE TOUT DÈPANNAGE LE CHÁSSIS DE CE RÈCEPTEUR EST
DIRECTMENT RACCORDÈ Á L’ALIMENTATION SECTEUR.
ATTENTION AUX COMPOSANTS RELATIFS Á
LA SECURITÈ!!
LES COMPOSANTS IDENTIFIÈS PAR UNE TRAME ET PAR UNE
MARQUE SUR LES SCHÈMAS DE PRINCIPE, LES VUES
EXPLOSÈES ET LES LISTES DE PIECES SONT D’UNE IMPOR-
TANCE CRITIQUE POUR LA SÈCURITÈ DU FONCTIONNEMENT,
NE LES REMPLACER QUE PAR DES COMPSANTS SONY DONT

AE-6B SELF DIAGNOSTIC SOFTWARE
The identification of errors within the AE-6B chassis is triggered in one of two ways :- 1: Busy or 2: De vice failure to respond to IIC. In the
event of one of these situations arising the software will first try to release the bus if busy (Failure to do so will report with a continuous
flashing LED) and then communicate with each device in turn to establish if a device is f aulty . If a device is found to be faulty the rele v ant
device number will be displayed through the LED (Series of flashes which must be counted) See table 1., non fatal errors are reported using this
method.
Each time the software detects an error it is stored within the NVM. See T able 2.
Table 1
How to enter into Ta ble 2
1. T urn on the main po wer switch of the TV set.
2. Program Remote Commander for Operation in Service
Mode. [See Page 20].
2. Press ‘VIDEO’ ‘VIDEO’ > ‘MENU’ > ERROR MENU
on the Remote Commander.
3. The following table will be displayed indicating the error
count.
Table 2
Note: T o clear the error count data press ‘80’ on the Remote
commander.
