652 channels? You were done. We had the same problem so we took the receiver to OZKAN on the one way street out of Fethiye, behind the Bazaar area, almost opposite Arcelik. They retuned it for 10TL and now we have 1000 channels, some blank, most rubbish. We had to go into the menu and delete a whole batch of channels because I think some of our guests wouldn't have been happy to come down and find there 5 year olds watching Italian hard core at 8 in the morning.
Wish we hadn't bought the thing in the first place but with 5 teenagers....
