What does tuner overload mean on a TV?
Overload is a very strong incoming signal that enters the external antenna and decreases the gain of the booster; in extreme cases, it will shut the booster down. Again, you will need to restart the booster each time the antenna is readjusted.
What is a tuner mode on a TV?
Get Ready for Digital TV! A digital tuner allows a TV to receive digital television (DTV) signals broadcast over-the-air by local TV stations. To find out if one of your TVs has a built-in digital tuner, check the owner’s manual or the TV itself for one of these labels: integrated digital tuner.
How do I know if my TV tuner is bad?
Some symptoms of this problem might be if your picture has reception problems; you are unable to tune to certain blocks of channels; channels change randomly; you lose the picture and then hear a high pitched whine;, there is noisy or muted sound (volume buttons have no effect) or the controls behave erratically.
What is signal overloading?
Radio Receiver Overload / Strong Signal Handling Includes: As the range of signals that any receiver needs to handle may extend over 100dB or more, the strong signal performance is important. Overloading can lead to effects that can mask the wanted signal and actually reduce the sensitivity.
Is a tuner the same as an antenna?
An antenna is an aerial. A wire structure which, to pick up TV signals, is typically mounted at the highest point in a house and connected by a coaxial cable. A tuner is a circuit that selects a particular signal from all those received by the antenna. Typically this is by tuning to a specific frequency.
What does it mean when the TV says tuner has not been set up?
If you getting an error that says No Signal, Tuner has not been setup, or No Channels in Master list, try the following steps. Make sure your source device is powered on. Make sure the cord is securely connected to your TV and Device. Cords may come loose for various reasons.
Can a TV tuner go bad?

What is amplifier overload?
As you are probably already aware, if signal levels within a system rise ‘too high’, then the circuitry will overload; it is no longer operating in a linear manner. These distortion, or noise 1, components, are signal-level dependent. In this case the noise components arise due to the presence of the signal itself.
What is receiver overload?
Overload or saturation is the maximum power level at which the receiving node is able to clearly receive the bits being transmitted. When the power threshold is exceeded, the saturation point of the receiver is reached and attenuation (inserting a loss between the transmitter and receiver) is required.
How do I fix my LNB?
Slide down the cover of the coaxial cable connector’s joint with the LNB output jack, gently pull the cable to ensure that the joint is firm and secure. If the joint is loose, frayed or corroded, you will need to replace the connector and screw it back into the jack.
