My existing TV arerial worked with one of my old freeview Sony TV very well. Recently I bought a Sony KDL-46nx725 3D TV set. HD Freeview channel works fine, but I can not watch normal freeview channel, screen shows broken picture with some cracking sound. This problem gets worse when TV aerial lined parallel with power cable. Questions:
1. Normal freeview channel needs stronger signal than HD freeview?
2. Are there any anti-interference TV aerial cable? Where to buy?
3. If this is the problem with week TV signal, Will aerial booster be helpful? Which model can you recommend?
