I got nine hd, abc hd on my lcd but not seven hd and ten hd-how do you get it?

Question

is it to do with my aerial?

do i need a set top box? :(

Answer 1

you should get a better antenna.  something that would find signals and bring them in better.

Answer 2

If you get any, you should be able to get all.  The signal from the other stations may be weaker.  Did you do a scan for channels when setting up the TV?  Did it find 7-1 and 10-1?  I would suggest turning your antenna to get a better signal from those stations.  You may want to check this site

It will tell you the location and distance of all the stations in your area and which ones you should be able to receive.
