ending a sentence with て, is ておく implied?


> 部屋から出て行った。わめきたてるテレビをそのままに **して** 。

I interpret this as

> [He] left the room, leaving the television blaring.

Firstly (though not required for an accepted answer), わめきたてる is confusing. Why
not わめきたてている?

More importantly, how can we end this sentence in して? Why not しておいた。?

Is it implied, since we use そのままに?




This is a case of 'right-dislocation', a constituent of the original sentence
has been moved to the right periphery:

わめきたてるテレビをそのままにして部屋から出て行った ➞ 部屋から出て行った、わめきたてるテレビをそのままにして

This is largely a strategy adopted in the spoken language, and the effect of
putting material at the beginning of a sentence is to add emphasis.

When a plain verb is adnominalized, the ～る form is sufficient to convey the
meaning of continuity for a verb like わめく, and it may be that ～ている in that
position emphasizes the state, rather than the continuous nature of the
blaring of the television.

The interpretation of ～ている in an adnominalized sentence depends on how the
verb is classified. Starting with the great Japanese linguist 金田一晴彦 in 1950,
it has been recognized that verbs can be divided into classes, like 'stative'
状態動詞, 'durative', 継続動詞, 'punctual' 瞬間動詞, 'durative-stative' 状態発達動詞, and this
affects the interpretation of various verb forms.

For example, 太る is a durative-stative verb, so 太っている人 and 太った人 are equivalent
in meaning. 読む is 'durative' so 読んでいない can mean 'I no longer read' or 'I have
not read yet', but the ～ていない form of 結婚する, a 'punctual' verb, 結婚していない, can
only mean 'I am not married yet', not 'I am no longer married'.
