Try it on the inverter if it works then your not getting enough power from the 12v or are you plugging it in a usb on the TV..?

Ok, start from basics where exactly is the tv plugged into? And with what type of plug?
Same question for the fire stick. Is power supply to the stick from a usb in the tv or another source?

Is your motorhome main control panel turned on? My Avtex TV doesn’t supply enough power for the Firestick in the HDMI socket. I have to plug it into the 240V system when on hook-up.

A fire stick needs a separate power source to the HDMI port it is plugged into in all cases.

It sounds like your TV USB isn't a 'powered' one, just an input for you to put a stick into watch stuff on the TV, some are powered, others aren't, try plugging it into another power source and you should find it works.

You should have some fuses for the 12v sockets so check if one has blown or come loose.

I assume we are talking about 12v sockets and not 230v (mains) ones as the mains ones won't work without you being hooked-up.

Does your TV have a 'power brick' that can plug into a 3-pin mains socket? If you look at the label, it will say the output voltage. Probably about 12V, maybe 13V. This brick changes the 240V AC mains voltage down to 12V DC, which then powers the TV.

The other cable that came with the TV can plug into a 12V socket, and power the TV from that. It plugs into the same hole in the back of the TV. Using that cable, you can run the TV directly from the 12V leisure battery, no need to have a 240V mains supply.

The inverter should not be necessary for this TV. An inverter boosts the voltage of the 12V battery to 240V AC, so it can power some devices from a standard mains 3-pin socket. It should be used with care, because it can quickly drain a 12V battery.
