you will need to move the Ariel in different places and you now should get a image
LNB stands for Low Noise Block. This device amplifies the weak incoming signal from the satellite and converts it to a signal that is usable by the television.
Antenna amplifiers are used to strengthen the signal being supplied to an appliance such as your TV. Amplifiers are necessary when the signal is weak and interferes with your TV reception.
weak signal strength. Call up the signal strength bar from the menu then raise or rotate the antenna until the bar shows an increase.

One possibility: if the signal is a digital broadcast and you have a digital-capable TV but the DVR has an analog tuner, the DVR would not see a recognizable signal, but the digital signal would pass through to the TV.
TV preamps can improve signal quality by boosting weak signals, reducing noise and interference, and enhancing picture and sound clarity, resulting in a better overall viewing experience.
Yes, you can still get reception with standard television ears, especially if you have a strong signal. If you have a moderate or weak signal, you may need to mount an antenna on your house though.
There are many things that cause the snow effect on the TV such as a loss of signal or electromagnetic interference. These things can usually be resolved by adjusting cords or cables on the TV.
It means you have weak siganl.
A TV snow storm, also known as "snow" or "white noise," typically occurs due to a weak or disrupted television signal. This can happen because of interference from other electronic devices, poor antenna connections, bad weather conditions, or signal processing issues.
Try rescanning the set. Did the antenna get turned to a wrong direction?
The disadvantage of automatic gain control, attenuating even the weak signal, is overcome by the use of delayed automatic gain control (dagc).
