Pixelating, ghosting, and snow on LCD TVs are often caused by a weak signal. There are different procedures for digital and analog signals. Information for each signal type is below.

Digital Signals

Digital signals cannot be fine tuned and are subject to the "Cliff Effect". The "Cliff Effect" happens with digital signals because they work on an all or nothing principal. If there is enough signal for the image to be displayed correctly the TV will display a picture if the signal ever falls under that signal strength the picture will not degrade, like an analog picture, the TV will just drop that channel.

Antenna

To get a clearer picture on a digital channel you must have a signal of at least 75%. To check your digital signal stregnth, follow these steps:

1. With the TV on, press MENU on the Samsung remote to bring up the Main Menu.
2. Use the ▲ or ▼ button to highlight Channel, and then press ENTER.
3. Use the ▲ or ▼ button to highlight Signal Strength, and then press ENTER.
4. If the signal strength is low, you must move your antenna to an area where your signal is stronger.

Cable

If your digital cable channels have a weak signal, you must contact your cable company to boost your signal. They may have to come to your house to check your signal.

The Signal Strength Meter does not measure digital cable signal.

Analog Signals

Both analog antenna and cable can be adjusted by using the Fine Tune feature. To use the Fine Tuning function, follow these steps:

1. Turn on your TV.
2. Set your TV to the station for which you want to improve reception.
3. Press the Menu button on your remote. The Main menu appears.
4. Press the Up or Down arrow button on your remote to select Channel, and then press the Enter button. The Channel menu appears.
5. Press the Up or Down arrow button on your remote to select Fine Tune, and then press the Enter button. The Fine Tune screen appears.
6. Press the Left or Right arrow button on your remote to adjust the fine tuning.
7. To store the fine tuning setting to your TV's memory, press the Enter button on your remote.
8. Press the Exit button to exit. 

Note: Fine tuned channels have an asterisk (*) on the right hand side of the channel number on the channel banner.
