In the corner or in a corner

[Nonverbis]

English Grammar in Use by Myrphy. Second edition. Unit 124.

In the corner.

But, the black dot is only in one of the corners in the room. And the picture of the corner of a cross of streets also
have a spare corner.

In this situation I am inclined to use an indefinite article.

Our TV set is on a little table in a corner of the room. Which corner? Just some corner. There are a couple of other corners there.

Could you speculate on this?

I don't know why, but we rarely use the indefinite article with corner. If we wish to stress that something is in/at one of several corners, we usually say one corner.

In this situation, I am inclined to use [STRIKE]an[/STRIKE] the indefinite article.
Could you [STRIKE]speculate[/STRIKE] comment on this?

See above.

"Our TV set is on a little table in a corner of the room."

I don't think "a" would be unusual or uncommon in that brief example. The primary focus is on the TV's position "on a little table".
