I need to use the cable remote to change the channel and the TV remote to change volume.
That is because your TV is looking at the output of the cable box (probably on channel 3 or 4) so the TV has to be statically tuned to see the cable box's output.
On the second question; I, and perhaps others, can't answer this without spending a lot of time to download manuals for both systems while you have them (presumably, since they are new) on hand. You didn't include the TV's model number anyhow so even that wouldn't be adequate.
The home theatre may have a receiver but what does it receive? Unless it also has channel capabilities that correspond to cable channels, it can't. The typical routing should be from the cable box to the TV S-video input and the sound can be routed separately from the cable box to either/or both, the home theatre's and also the TV's audio inputs.
When I am installing new stuff, I make a sketch of the routing I want (or have) to use. To me, this is less confusing than the supplied instructions.

Channel scan only finds 1 channel with basic cable setup on LG 42LD520


if you have a cable box just plug the cable box into a scart socket on the tv, switch the tv to the scart input and use the cable remote to change channel?Scanning for channels wont find anything because you are receiving the channels on a cable box. If you are refering to standard or digital tv signals and your not receiving any channels then either you are only scanning analogue tv and therefore wont pick up any digital tv channels, or your ariel is inadequate to receive an acceptable digital reception and will need to be upgraded. please state country you are in and what you are expecting to receive

I can only able to see 65 channels in my new samsung t.v[LCD]but in my calbe there are more tahn 70 channels....how can i see the all channels


When you scan for channels, make sure you choose "cable" for the setting under the "Antenna" tab.

channel --> antenna --> choose cable

This should let your TV show more channels. Most cable companies issue cable boxes now a days, which you plug into your TV. You usually change the channel by using the remote for the cable box.

Hope this helps

Hi mfaille
I`m going to help you with your setup but first;
Which connection are you using from the sat receiver to the tv?
Coax / standard rg6 cable?
Did you try to manually add(in the menu/tuner setup/find channel/add) the channel you need ?

Lg lcd tv keeps changing chanels


Come on, lets try to solve this. Take the batteries out of the remote so it can't interfere and try changing the channels and volume with the buttons on the tv. If this works then someone has spillled something onto the remote and gummed it all out. You simply need to take the remote apart and clean it out. If the buttons on the tv do th same as the remote did then yes, take it back.

My remote control for my polaroid tv wont change channels up and down.the channel button isnt working for the tv.everything else is working.


You may be able to program your cable box remote to control your TV in addition to your cable box. When they initially set up your cable box they probably left a pamphlet giving you instructions on how to program your remote. I'm not sure why you can't change the TV channels manually but this may give you a work-around.
