We have an outdoor antenna on roof, a smaller Samsung HDTV and a 55" LG HDTV. We get over 10 channels on the Samsung and only 5 on the LG. We used to get the same amount of channels on both, but recently it is not. We also have a splitter and a line signal booster. Thanks so much.

If connecting before the splitter is impossible, then you will need to use the same cable some-how. Moving them both to the same room and testing them one after the other would also allow you eliminate everything but the set itself.

It's a two way splitter and swapping made no difference. Thanks

move both sets to before the splitter so that only one set is directly connected to the antenna. Rescan with that set. Then do the same for the other set. This test rules out any cabling and other issue. If the channel count isn't the same, then perhaps the tuner on the set that has lower count is broke or the signal may just be weak enough that a poor tuner can't bring in the channels.

Ok tried that and no changes so I'm thinking it's the differences in the tuners-larger tv (55") is LG and smaller tv (42) is Sansui. Is there something we can add to larger Tv to bring in the signal better?

hmmm... potentially not BUT you could try an "box /standalone tuner" and then feed that output (via hdmi) to the tv. A standalone tuner might have more sensitivity and be able to get all the "seeable" channels. Their cost is relatively cheap ($30-50) so it might be a reasonable option. Get one from a place that allows returns "easily". There are a number of makers so you might have to find one that is "better than the rest"... but it might not even be an issue... first one / choice might work perfectly fine.

The problem with trying to do things like an in-line amplifier is that it will "amplify" the whole signal, including the noise "floor", which if the tuner that is being fed by the signal is poor, will still have a problem "decoding" the incoming signal.
