Before you condemn the signal board, you need to make sure the "run" part of the PS is working.
Take the meter and find the "PS on " line going to the power supply. It may not be labelled that--but will be similar. (pwr, pwr. on, etc). While turning on the set, with the front button or remote--see if that line changes, (either from 0-3v. or more--or possibly the other way--3 to 0. it should be a noticeable, definite change. It is does NOT--then you likely DO have a bad signal board. If it DOES_-then something is wrong with the run supply on the PS. You can VERY easily have full standby--but still have a run supply problem.
