This week sees the first stage of the digital television switchover for 4,853,500 homes in Greater London.
From 6am Wednesday 4th April 2012, you must perform a "first time installation" retune (sometimes "Factory Reset" or "Shipping Condition") on your Freeview box or television set if you use the Crystal Palace, Hemel Hempstead, Reigate or Guildford full service Freeview transmitters.
This is because the old low power "multiplex 1" BBC service will be replaced by the high power BBCA multiplex on the old analogue BBC TWOfrequency. Also, ITV 1 analogue will move to the BBC TWO analogue slot, except at Hemel Hempstead.
Crystal Palace (starts midnight, ends by 6am) - BBC TWO analogue closes on C33, ITV 1 analogue moves to C23 from C33, Multiplex 1 closes on C25-, Multiplex BBCA starts on C23.
Guildford (starts midnight, ends by 6am) - BBC TWO analogue closes on C46, ITV 1 analogue moves to C46 from C43, Multiplex 1 closes on C49-, Multiplex BBCA starts on C43.
Hemel Hempstead (starts midnight, ends by 6am) - BBC TWO analogue closes on C44, Multiplex 1 closes on C48+, Multiplex BBCA starts on C44.
Reigate (starts midnight, ends by 6am) - BBC TWO analogue closes on C63, ITV 1 analogue moves to C63 from C60, Multiplex 1 closes on C31, Multiplex BBCA starts on C60.
Because the Multiplex BBCA service carries some channels (BBC FOUR and BBC radio stations) that are also still being broadcast as part of the existing multiplex 2, after you retune, you will see these channels duplicated. This will be resolved when you do a full retune in a fortnight.
living in orpington receiving from Crystal Palace. I have performed numerous retunes and factory restarts. Once I do - all channels work find, But after about two minutes I get a message saying 7 new channels received This then makes most of the BBC channels dissppear. BBC 1 which was on channel 1 goes completley - BBC which was on 2 now appears on 814 . I have a DSTB ( ferguson ). Any pointer to getting BBC 1 back ? Most of the other channels seem to be working
