Hi all, this is the first time I have ever contributed to any forum before today, I was given a TV which has this problem.
I tried the fix in the last posting, the clicking on / off of the relay has stopped, No relay on click and no LEDs when connector removed from the PS board. I'll keep looking and check the voltages with my DVM. There must be many issues that cause the same problem. 
I would be very happy if someone has another suggestion. Thanks for the helpful leads. Happy Christmas to all.
