Halogen lamps are well known radio-frequency interference generators. 
Your best bet with the lamp is to replace it with a lamp of some other 
technology. Stay away from any touch lamp as well, or anything with 
(most) dimmers, as these are also bad for interference.

What you need to determine is whether the interference is being 
conducted into the TV set via the AC power cable or is being picked up 
via the set's antenna. The easiest way to test this would be to 
completely disconnect the antenna from the TV and see if you still see 
the interference. (I am assuming that your set won't go to a blank 
blue-screen here when on a weak signal.) If the set shows no 
interference with the antenna disconnected, the interference is coming 
in via the antenna or the antenna cable-connectors/etc.

Let me know what kind of lead-in wire or cable is on the set (coaxial 
cable or twin-lead) and how you have it connected to the set, antenna, etc.

As for the hair dryer, that you'll likely have to live with. Small 
appliances are fairly difficult to interference-proof economically. And 
you don't use them that often.

We'll talk more about ideas after you answer the above :)
