It sure sounds like this is the same problem as the one discussed in the second thread Edmund mentioned.
But that means this TV doesn't respond at all to TV/0761 (which might be consistent with what Tom said. I'm not sure about the meaning of some of the things Tom said).
The TV responds to Philips TV commands, but one of the Philips TV commands destroys it. That presents a serious danger when using this TV with any universal remote.
To fit that theory to Tom's description of events, we must assume the SWAP button was already programmed by learning or KeyMove to the Philips TV signal that causes the harm. Programming a setup code (TV/0761 in this case) has no effect on previous learned signals. So it wouldn't even matter whether TV/0761 defined that key or what it defined it as. The previous KeyMove or learned signal remains in effect.
If you get another of this TV with the same stupid firmware, I think you can get the working functions to work using a Philips setup code. But you better be very sure you know in advance which command in that Philips setup code trashes the TV, so you can override the programming (with a different KeyMove or learned signal) so that command can't be generated by accident.
