Re: Samsung HPT5054....
Yes, control board/logic board. No that would be rather uncommon to lose all those boards at the same time.
If you had a scope I suppose you could check the waveforms but I couldn't help you with that.
Maybe someone could respond if it's safe to run the set with only one buffer installed at a time because I don't remember. That would help rule out the buffers as a source of the problem but I still don't think they are.
I still think you have a bad ymain followed second by a control board. One is cheaper that the other to rule out first.
