yes

To check the compatibility of the Fire TV Stick with your old Samsung TV UE40F6200AY, follow these steps:

1. Check for an HDMI port: The Fire TV Stick requires an HDMI port to work. Your Samsung UE40F6200AY TV, being a 2012 model, should have at least one HDMI port.

2. Make sure the HDMI port is working: Try connecting another device (such as a computer or another media player) to the HDMI port to check that it is working properly.

3. Connect the Fire TV Stick: Connect the Fire TV Stick to the HDMI port on your TV and make sure it is also plugged into a power outlet. Follow the on-screen instructions to complete the setup.

4. Check your TV settings: Make sure your TV is set to the correct input to receive the signal from the Fire TV Stick. Usually, this is done by selecting the corresponding HDMI input from the TV menu.

If your TV does not recognise the Fire TV Stick, it may be due to specific problems with the HDMI configuration on older Samsung TV models, as mentioned in some cases. In that case, you may have to try changing the HDMI port or resetting the device.

No. But there are apps in the Google Play Store that can be used to retrofit AirPlay.

Regarding 1: the stick runs on my old Panasonic via HDMI and works perfectly. It should therefore also work on the Sony Bravia.
Re 2: The "Play SRF" app can be selected via the stick, where live sports streams can also be accessed (as on the standard app). The "SRF Sport" app cannot be accessed. But I have compared and the live streams on "Play SRF" are the same as in the "SRF Sport" app, at least today and tomorrow.

I don't know, I only use Netflix and Amazon Prime. Sorry

not in my experience, the apps are pre-installed, there is zatoo, netflix etc...

that's hardly a question. also chromecast is a totally different product.

We use it exclusively for Netflix. That works well.
I don't know Teleboy, I don't use it and therefore can't say anything about it.
