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.
