Our 32inch Samsung TV (UE32M5500AK) no longer recognises Our Humax 5000. This is in a bedroom, & used to work. A 40 inch LG TV in another room still streams ok, but with a wifi extender.

On the Samsung, I accessed the Humax with the “source” button, but since we lost the wifi connection, I have been unable to get things back to normal. The only way that the TV would accept the password was after I held down the power button untl the Samsung logo appeared.

Any ideas on setting up the Samsung?
