Re: Sony KDL-46EX400 2 blink error code
Need to look at the circuit diagram of the latching circuit since it receives 3 signals (excessive 12v, excessive PFC voltage, excessive temperature) which any one of them can trip the circuit. It is a matter of finding out which one is tripping or the latching circuit may be at fault itself, this is where the diagram comes into play to narrow down the cause of the problem. You can disable one of the 3 signal at a time to find out which one is sending that signal to the latching circuit.
