for chassis sony B3E:

Fault :set goes to stand by and after pressing pr+or pr- led flashes 11 times.

This fault indicates a fault on jungle chip Tda8366h. The truth is that
the sda or scl I2C bus is busy.

Check the Voltage at resistors 4,7k R77and R88,you should measure 3,8~4,2 Volts DC.

If you don't have those voltages check 5Volt line from p/s
rectifier diode on secondary winding 5volt regulator,capacitors,resistors
or a faulty chip that is conected
on the bus(disconect pins sda,scl pins from all ic of A board and conect
them one at a time until you find the faulty that holds voltage low).

if there is no problem with the i2c bus, check lopt and Horizontal transformer.
