The professional recommendation is that you should not mount a TV on your chimney breast if the temperature you measure is above 100°F, as it is no longer safe. However, anything above 90°F could cause damage to your TV so it is important to check your manufacturer's suggestions. Click to see full answer

Testing
The best way to tell quickly is to just give your chimney breast a temperature check. Generally, it’s best to keep electronics away from anything warmer than 35-37 degrees Celcius. They don’t stand up well to that type of heat, and TVs already can get quite hot on their own.
Type of Fireplace
This is specifically important in terms of gas vs. solid fuel fireplaces. A gas-powered fireplace can easily get up to temperatures that could damage electronics, but it can also be turned off.
What About Wiring?
Wiring is always a concern when mounting a TV. Exposed, disorganised wires are just plain ugly. But when you add in a potentially hot chimney breast, it gets more important. They can melt and even catch fire if done poorly or exposed to high heat, which is… less than ideal.
Mounting to Masonry or Concrete
If your masonry or concrete chimney breast is well insulated enough to accommodate the electronics, it’s possible to mount it directly on. While the manner may vary, you can double-check with your manufacturer. To do this, you’ll need a few things:
Can you drill a liner in a fireplace?
If the liner is to your fireplace and you do not wish to use them yes you can drill but as stated above there could be vermiculite. It is your decision but should the flue be ever brought back to use then a new liner/other work will need to be conducted .
Can a drill cut through a chimney liner?
The drill can cut through the liner quite easily and you need to put a camera down the chimney to see if the void has been filled , I would look for paperwork about the installation even phone the installation people up and ask directly

Complete DIY simpleton here (but I'm trying!), so please bear with me...

Whether the thread is about mounting a TV bracket or speaker brackets makes no difference. It's all about dealing with walls, which is the essence of what you're asking.

Thanks lucid.

When I used the magnets though, there seems to be metal strips going along the edges of the chimney wall and around fireplace space at the bottom, what's that for?
Lucid
Thanks lucid. Having looked through the links (particularly the firstl) I'm almost certain it's dot and dab and explains why I couldn't find any studs.

Thanks for the information all. That's given me a good starting place for what needs to be done.

Type of Fireplace
- This is specifically important in terms of gas vs. solid fuel fireplaces. A gas-powered fireplace can easily get up to temperatures that could damage electronics, but it can also be turned off. Solid fuel fires, on the other hand, can quickly rise in temperature before you know it. If left unattended, it’s entirely possible that a wood fire could quickly and irreparably damage a TV.
