There is no such thing as 'throwaway culture' instead there is economics. In developed countries it simply is cheaper for the consumer to purchase a new LCD monitor than simply pay for a skilled engineer's labour which would arrive at the same price in addition to the uncertainty and time this takes.
In less economically developed countries, it is exactly the other way around, electronics are rarely being thrown away, in this case the repair engineer's time is significantly lower than the price of most western electronic products.
