Why is my TV suddenly saying no signal?
First check that your TV is set to the correct Source or Input, try changing the Source or Input to AV, TV, Digital TV or DTV if you haven’t already. If your “No Signal” message is not due to incorrect Source or Input being selected, then it’s most likely caused by a set up or antenna fault.
What does no signal mean?
“No Signal” is a message coming not from your computer, but from your display device, indicating that it has nothing to display.
Why does my TV keep losing signal?
A faulty amplifier is a very common cause of poor TV reception. The signal goes in fine and comes out awful. It’s a simple fix usually – replace the amplifier. Another common reason that cause this is the constant disconnecting and connected of cables such as in wall plates which can break and ruin the TV signal.
