I assume you also have no satelite dish. You are probably on an antenna (or rabbit ears). If you don't already have one, you need a DTV Digital to Analog converter box. I am assuming you want to snag broadcast signals from the air, like in the good old days before the massive digital conversion of most broadcast stations. Might be hard to find one in retail stores, but start with WalMart or Best Buy, and if that fails you might check eBay (I think it is too late to get the government rebate which absorbed almost the entire cost of the box, but you might check around on Google searching on 'DTV Digital Analog Rebate'). The DTV converter will change the digital signal now being broadcast on most stations to an analog signal that your antenna connection will recognize. Without a signal, you can't program the channels because the tuner has nothing to latch onto. After getting a signal you just follow instructions for your TV to search for channels -- if you don't have instructions you might have to play around with the menus on-screen until you find what you need, but essentially it will be obvious when you see it ... the on-screen instruction will say something like select or program channels, and may let you choose manally or search automatically (choose automatically after hooking in the DTV converter to find all channels). Hope I understood your problem, your description is a bit vague.
3 Connect cable or antenna, then select OK to run Auto
Program
ā¢ If you have cable and antenna available, please connect cable first.
ā¢ IMPORTANT: Auto Program is only effective when cable or
antenna is connected. If you cancel Auto Program before completion some channels may not be
available.
4 Auto Program will scan for available channels from the signal source directly connected to
the TV's CABLE/ANTENNA input and may take sometime to complete the process. Follow
the help text provided on the screen to run Auto Program.
OK.
press and hold the POWER button
on the TV control panel for 5 or more seconds to reset the TV.
Then connect the TV tt any source like outdoor areiel or cable box etc, select the appropriate input, and retune the TV. First of all, connect it to an external antenna, and set it to autotune.
ā¢ You must configure the ANT/CABLE input source before
programming channels (-left-hand column).
ā¢ If the ANT/CABLE input signal type is set to Cable, the
automatic channel programming process erases channels
that were previously programmed into the TV's memory.
ā¢ If the ANT/CABLE input signal type is set to Antenna, the
automatic channel programming process adds newly found
channels to the existing set of programmed channels (and
does NOT erase channels that were previously
programmed into the TV's memory.) To remove an Antenna
source channel from the memory, you must manually delete
it.
ā¢ To tune the TV to a channel not programmed in the channel
memory, you must use the Channel Number buttons on the
remote control.
ā¢ Programming channels when the ANT/CABLE input is
configured for Cable will take substantially longer than when
the antenna input is configured for Antenna. This is normal;
however, once channel programming is finished, you should
not have to repeat the programming process again unless
your Cable TV service lineup changes significantly.
Find out the received channels are clear or not. If they are clear, your TV is perfect, and the input device you connects ot the TV is faulty. OK.
