I have a 10 month old son. He's able to stand on his own and crawl, and his favorite place to be is at the TV stand. I have a 75" TV in a place he can unfortunately reach. There is no possible way for us to mount it to the wall or move it, as it's in the only place it will fit.
My concern is that he likes to go up and hit it with his hands or with a toy; seeing how expensive this TV was, I'm terrified he's going to break it. What are any ways I can prevent that?
I'd be more concerned with a 75" TV falling on my infant and hurting him! A 75" television can weigh up to 100 pounds - that's a lot of weight to be falling on a 24 pound infant.
There are a few things you can do to protect the television and the infant. One is to use safety straps - these don't mount the television to the wall, but they do attach to either the wall or the stand, and prevent it from tipping forward.
Another is to gate around the television - the whole way around. You don't say how it's placed in your house, but however that is, you can use gates - just perhaps a lot of them.
Another option might be to have a larger TV stand. Babies want to touch and hold onto things while they're learning to walk, and so a larger table/stand that gives a good amount of space before the baby gets to the television will help a lot here as well.
Mainly, though, a child that age should not be unsupervised for any period of time - so the best protector for your television is yourself. Kindly teach your child not to throw things at the television, and redirect your child in more safe directions, as necessary. And, perhaps, reduce your time in front of the television - the things you're interested in, your child will be interested in.
I will not address how to protect the TV from toppling over. But to protect the TV from impact from toys (for example), screen protectors are sold which you can affix to the front of the TV. These are giant-sized versions of the screen protectors people put on their mobile phones. They are expensive; a quick search shows several in the $300-$400 USD price range. Whether that is worth the cost will depend will depend upon the price of your TV and how likely you believe it is to be damaged.
Swap the TV out for a projector with a roll-up screen mounted to your ceiling.
That's totally kids proof, not too expensive and gives you a larger screen diameter.
Also, you can now use the wall behind the projector screen.
TV stands don't have to be mounted to the wall these days. I have a 65" TV and the most surprising thing is how light it is (compared to the older tube TVs, which weighed a ton). Thus, you can have a TV mounted to a stand (with or without furniture).
Another option is to get a higher piece of furniture. I built a TV stand a few years ago that's about 3ft(1M) tall. Makes the TV harder to reach for your child.
A TV cabinet with a roll up door. And put some kind of childproof latch/lock on the door.
There don't seem to be a lot of pre-built options but you can DIY this or get one made custom. Since this is kind of a niche item, I would personally recommend a normal base with a detachable hutch that has the actual doors. Then you can disassemble it to move it or if you decide you no longer need the doors.
Don't forget to 1) secure the hutch against falling over by securing it to the wall, and 2) have an access hole in the back of the hutch to still secure the TV directly to the wall (to prevent falling over).
