hi been at my mums house today to fix her tv been its now the 3rd time in a year because the two wires that connect together one end going into the house other to the dish it has got wet and is a little rusted so i got a new male to female connector and took old ones off cut the wire and exposed a new peace of the copper wire inside the cable put the new male to female plugs on like i did the other 2 times and tv worked fine but this time it did not work i did get it to kind of work don't know what i did but it picked up all channels but tvnz channels but my mum thought she could fix it and made it worse now we get nothing but sometimes mediaworks channels will show up for like a split second

what can i do ??? and this time when i get it working im going to make sure it tucked away where it will never get wet again
