Anyways, I'm not giving up on it..

I had a closer look at the circuit and it appears to me that the relay
can be controlled by both the uP and a separate protection circuit.
See the bottom middle section of page 88 of the service manual.

When the TV shuts down, measure the voltages across R599 and R598. If
they are both around 0.6V, then the OCP latch has operated. This could
be due to an overcurrent on the B+ supply rail, or a missing vertical
deflection pulse.

If the latch has not operated, then the uP would have opened the
relay.
