Now, dilemma is when something is malfunctioning or not working properly. So when we put them together, technical dilemma might mean that you are having a difficulty with your electronics or a technical difficulty. Hope i helped!
Some technical definitions: More formally, a social dilemma is a collective action situation in which the Nash equilibrium results in outcomes below the Pareto optimal. A dominating strategy is a strategy that yields the best outcome for an individual regardless of what anyone else does.
