after service vs warranty

[keannu]

Is "after service" not stand English? Does it have to be replaced by "warranty"?
In Korea, it's widely used for the service provided by companies after we purchase a product. The company usually sets the period during which they perform free or a little bit paid service for broken goods.

Thanks a lot! You understood me quite right. So I think "after service" is Konglish(Korean-style English).
Then,do you say like this? "I applied for/got warranty service to fix my broken computer"
