Define ethical? within in itself, or in correspondence with?

Are the fans all starting up? The symptom you describe is often associated with a faulty fan. Also could be a failed lamp, as the projector will shut down if the lamp does not strike within a defined time, although in this case the 'lamp' light should come on

An ordered pair is made up of two values written in a specified order. In functions, an ordered pair is made up of a value from the definition domain followed by its corresponding value in the range.
To a corresponds t thus the pair is (a,t)
To b corresponds s, the pair is (b,s)
To c corresponds q, the pair is (c,q)
The last pair is (d,t)
You can now define your function as a set of ordered pairs f: {(a,t),(b,s), (c,q), (d,t) }. When you write the set, the order of the pairs is not important. Just make sure THAT IN EACH PAIR the first listed is from the set {a,b,c,d } and the second listed is from
{t,s,q }. The second t in the last set cannot be written because no repetition is allowed in sets.

Notice the plug is sectioned into two or three bits by black lines? Each section corresponds to a 'connection' within the jack--one for each of the stereo channels

If you are pushing the earphone plug deep enough into the jack to make contact with the respective sockets and are still not getting all (both) channels, most likely one of the wires connected to the jack (socket) or the corresponding circuit (board) has either shorted out or is no longer connected.
If you can open the device, look for a thin red or black wire that is no longer connected/soldered. Splice it or re-solder it.

Failing that, the jack itself may have cracked (due to excessive bending when you insert the plug).
