ABSTRACT:
A method of automatically disabling a low noise amplifier (LNA) that serves to boost weak video signals in a TV tuner, when the television receives a cable TV service. The method involves storing the total number of preset programs assigned during an initial auto-tune setup operation. If the total count exceeds a predetermined threshold, this indicates cable TV service whose signals will not require boosting. The LNA is then disabled to avoid interference between programs on neighboring channels.
