All good questions above. Obviously, if the transformer isn't putting out voltage, there's no sense in looking at the board! Ditto with the power to the circuit. I guess I assume too much, making sure there's power is obviously the first thing to check.
That looks like the old brick circuit board, but it's been quite a while since I've opened one, and I've never opened a new one. However, the odds of finding that obsolete relay in the new one would be very remote.
