If you are having problems with your screen mirroring not picking up your TV, it could be caused by a number of different issues. First, make sure that both the device you are trying to mirror and the TV have Bluetooth turned on. Also check if they are compatible with each other; some devices may only work with certain types of TVs or vice versa. You should also ensure that your device is connected to the same Wi-Fi network as your TV, and that both devices have been updated recently. Finally, try restarting both devices before attempting to connect again - this can often fix any connection issues. If these steps don't help resolve the issue then it's likely there is an underlying problem which will require further investigation or even professional assistance in order to get it fixed.
