I once had this problem a while back. Its your settings. Make the bottom half of the TV a "O" and top of it "X".
See if that works. Otherwise, post the tileset and I can set it, screenshot the settings and post ^,^
I tried that but when I walked up to the Tv I could go underneath it.
Is this what you mean by posting the image?:

I'm not sure if this will work but it's something to try
in the tileset area place go to passage (4 dir) and
on the tile make it so the bottom of it is an arrow and
the other sides are the dots
I got the same results from above.

just look up "pixel-movement script". i think that'll help your problem with getting close to things
I added it in and the problem is still there plus there's like an invisible wall on the sides of the rug.
