If your TV is displaying the Welcome Bienvenido message, it means that the TV is not receiving a signal from the input source. This could be caused by a number of things, including:
-The input source (e.g. cable box, DVD player, etc.) is turned off or not properly connected to the TV.
-The input channel on the TV is not set correctly.
-There is an issue with theinput source itself (e.g. a loose cable connection, bad video output, etc.).
If you're sure that all of your connections are secure and you've verified that the input channel is correct, then it's likely that there's an issue with the input source itself. In this case, you'll need to troubleshoot the device to try and resolve the problem.
