These were a badge engineered TV sold by Dick Smith Electronics in Australia. Inside all Samsung parts. Maybe somebody can recognise the actual model?
There is no PS-ON signal being generated by the mainboard. When the PS-ON signal is jumpered to earth the power supply fires up and all voltages are spot on (Vs, Va, Vsc etc).
The mainboard had some sort of brown goo on it (as shown in images). Has the consistency of contact adhesive. No signs of any spill on the external back cover. I couldn't shift it with methylated spirits; I had to resort to carefully removing with a very small blade screwdriver. Anyway, that didn't change the situation.
So any hints to progress from here. Do people agree it appears to be a failed mainboard? I can get a secondhand mainboard for about A$100.
The TV appears to be 2012 model, and it's in very good external condition. I'm reluctant to canabalise a good looking set, but then again it needs to be economical to repair.
