Another thing to watch for with loss of signal symptoms is AGC issues.

Voltage checks are your friend here monitor AGC, tuner and IF voltages. If the AGC voltage is changing so as to reduce IF gain (instead of increase it) in step with signal loss then that is your problem.

If it gets to the point where it wants to stay dead, and you have a B&K analyst or the like then tuner and or IF injection may show a bad stage.

[EDIT] Wayne beat me to AGC.
