I am in Northampton on the Sandy Heath transmitter - I have read a few of the posts here and am experiencing the same problem as a number of other people. Since the work was done on 9th, I have re-retuned my TV numerous times each day but am still missing a good number of channels i.e. ITV3, 5*, 5USA etc. all of which I had previously. I have followed the suggestions and re-tuned with the aerial unplugged then re-tuned with it plugged back in but still no joy.

Lisa: Carry out a "factory reset" sometimes called "default setting" or "first time installation" dependant on equipment, BEFORE carrying out another auto-tune, as ITV3 from Sandy Heath changed to Mux channel 51 on the 9th as well as its power increasing to 170kw from the reduced power it had been running on.
Another point is, that due to your location you might be picking up signals from an alternative transmitter, and so if after carrying out what I suggested you still cannot receive ITV3 reset the TV again and follow this by manually tuning in Ch51, giving an update on results as well as the model of TV or box you are using.

I live in Peterborough. Before the re-tune IO got ITV3 and the other channels really well on 31. After re-tune to c51 nothing. I thought it was supposed to improve signal reception.

Davdi: Carry out a "factory reset" on your TV or box before carrying out an auto-tune, as the SDN multiplex on Ch51 is being received at not far off 100% strength in the Stamford area as I have just checked it.

Hi jb38
many thanks for your quick response and advice. I have done everything you have suggested including the 'factory default' re-set, another auto-tune and have also tried to manually re-tune channel 51 which didn't work at all, therefore, unfortunately I am still missing my 4 channels that I had previously - based on your advice, even IF I did get ITV3 back, I am still also missing 5*, 5USA and Challenge. This is getting soooo frustrating now, especially when things get changed that are 'supposed' to be an improvement. :-(
Any further help or advice you are able to give me would be very greatly appreciated. My TV is a SAMSUNG. Many thanks.

Lisa: If you carried out a "factory default" before re-tuning then thats a bit odd as starting afresh generally cures problems such as yours, and of course when you mention Challenge then that brings another mux into the equation as its on mux Ch52 and not Ch51 that ITV3 / 5* and 5USA operate on.
However, to enable me to know if you are receiving any of these two muxes plus an additional can you receive the following programmes: EPG11-Pick TV / EPG19-Dave / EPG27 ITV2+1 / EPG38-Quest / EPG12-Yesterday / EPG24-ITV4?
Maybe along with the answer you could also provide the model number of the Samsung you have plus a post code, or at least on from nearby (a shop / post office etc) as I cannot assess the signal levels expected in your area without this knowledge.

I am having similar problems to Lisa. I live to south of northampton and am targeted at Sandy Heath transmitter. Reception in this area has never been great but is significantly worse since retune was required. I am getting no signal or poor reception on ITV3 (10), Pick tv (11), Dave (19 now much worse), E4+1 (29) Price drop (37), Gem tv (43), CH5+1 (44) Challenge (46) and food net (49). I have done a reset to purge the memory and auto retune and still have problems. TV is a samsung UE32B6000.

Just to confirm aerial position and type, because of historically poor reception aerial is a large quadra pole on top of a 3m mast on top of chimney.
Perfectly adequate until latest changes.

Thanks again jb38.
Ok here goes - I can still receive Pick TV (11) and Dave (19) - both crystal clear as always, however, I can no longer get Yesterday (12) nor ITV4 (24) and get a message saying 'serivce not available', and I no longer even have a Channel 27 for ITV2+1 nor Channel 38 for Quest - again, all of these I previously received and watched regularly prior to 9th May.
Apologies, I confused Challenge on 46 with Quest! - I CAN still get Challenge but not Quest.
Of course, sorry - my postcode is NN5 6YE and TV model number is a Samsung LE32B551A.
