Here we go again.

C1: R14-17, R22-24
C25: R14-17, R22-24

This will give you the knowledge needed to finish a chunk of the puzzle.
After that, think symmetrically to fill in the lower part.
(If you still need a hint, fill in R25: C8-9)

Now for the top part of the puzzle.

The 4 in R5 goes in C6-9.
The two 6's in C7 and C8 both go in R5-10.
They form the vertical line of a Y. (So add a 'V' shape on top of it, using the same strategy as for the bottom part)
To the left is a TV-screen (I think) with the words "Yo" on it.

Remember to always test your puzzles before submitting.
Have a beautiful evening.

You mean "to the 'right' is a TV-screen". But otherwise, great hints, Deathgrips! Thanks!

Yes you're right Strange_Victini, sorry for the confusion.

To the right is a TV-screen, my bad.

Thank you for the hints Deathgrips and Strange_Victini.
