Yes, there are quite a few TV stands with a built-in fireplace. You can get one that is built to sit against a flat wall, or you can get a corner TV stand. Some companies specialize in these, although not all companies make ones that come in black.
It is important to note, that while consolidating these two items into one single piece of furniture, there are quite a few trade-offs that you have to consider. Anytime you are combining so much into a limited amount of space, there are going to be sacrifices that will need to be made.
First of all, because you are getting a stand for a flat-screen TV on top, they need to leave plenty of space in the unit for things like shelving or an adjustable shelf like a bookcase. This is how they leave room for media storage, a DVD player, or gaming consoles. Unfortunately, with a bulking fireplace built into the body of the stand, you are left with very little storage space, a little to no storage cabinet, and any open shelves will be limited in size.
Also, because room needs to be left for these features, the fireplace itself needs to be compact. This smaller fireplace size means that they are making quite a lot of sacrifices in its functionality and performance. The fireplaces within these stands tend to have trouble sufficiently heating a home and they have flame effects that leave a lot to be desired. Usually, they are nothing more than some simple LED lights.
Unless you really have your heart set on one of these units, you should really consider getting a standalone electric fireplace that matches your TV stand, rather than getting one built inside of it. If you must have one built-in, instead of buying one that is already inside of it, find a TV stand that has adequate space for a fireplace insert. By doing it this way, you can find a premium insert from a trusted company rather than being stuck with whatever fireplace comes with the stand itself.
