Is the TV a flat screen, or standard design with a deep back?

Please post a picture of your TV so we can see what you have to work with.

You can hang your tv on the wall and then frame it with a wood frame. Here is an example https://www.hometalk.com/11099196/diy-40-wood-tv-frame-works-for-tvs-that-tilt-and-rotate-too

Do you have a pic?

You may be able to make a wood frame that just goes around it without having to hang it on the wall. I am not sure about painting it but if you masked off the tv screen and used some primer you may be able to spray paint it. Good luck!

can you show pictures ?

Hello Joyce. Use sticky backed plastic - Contact or tape or Modge Podge fabric onto it or even decoupage with paper. Have fun. Paint it the colour of your walls maybe.

Are you wanting to paint it? If so I would tape off the tv area with some paper and painters tape and then paint the frame. I like Fusion mineral paint and chalk paint. Here is a post. https://lifeonsummerhill.com/how-to-paint-with-chalk-paint/
