Ihave the same TV model wich can not start, standby voltage is there, power_on come back from main board but drops immediately to zero.
I have the schematic diagram but I could not identify the cause.
I looked to the circuit of power_on but did not understood who the circuit works and why the voltage dropped down.
I am still in learning phase, I am not expert.
so please help if it is possible dear experts. I will attach the schematic diagram with this post.Re: Sony kdl-40r473a
