I suppose that I could sense 5V from the USB port -- if it is switched. This would take some time to setup, time that I don't have -- assuming that I have a couple spare conductors back to the processor in the rack that I dig out.
Friendly IR codes would be much more practical.
if typical samsung codes aren't working, then the only thing I can think of to try would be a firmware update.
if that doesn't help, you have a toggle only TV.
