SONY KDL-46W2000 Service mode led blinking code and power supply circuit
SONY KDL-46W2000
ERROR IDENTIFICATION
The
identification of errors within the WAX2F chassis is triggered in one
of two ways :- 1: Busy or 2: Device 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 faulty. If a device is found to be faulty the relevant
device number will be displayed through the LED (Series of flashes which
must be counted).
