With mine it only relay clicks when you turn the master switch on , it's not a soft start.
If it's no longer cycling on at all and no relay clicks, no sos.
Sounds like the A board may have quit which is unbelievable but when it comes to power on sequence and checks, Tom's one of the best for that.
I can't see anything we did should cause the A board to die, could be a missing voltage.
We know 5v standby is there since the front LED is lit.
There's no justice. I had a similar blow, cleared the SS short only to find SOS1 waiting for me on the A board. It was functional until it came time to power the panel up.
I hope someone can keep working with you on this but if you need an A board, I expect that may be a challenge.
A couple of longshots, Maybe try the remote, sometimes the TV goes back to it's last state when power is re-applied or try holding the power button and see if it resets.
