Linda, Thea, Matt (and others with the same issue): In addition to knowing whether my suggestion of unplugging the aerial at 30% solves the problem, it would be useful to know the make and model number of the problematic box or TV.

Dave: I have just given that a try, the blue box came back it seemed to take a bit longer and the signals on other channels seem to be weak, turned off and back to square one, any other suggestions...

Dave: the tv is a Samsung Slim about 3 years old, the digital box is about a month old and is a (argos)bush BU11FVZS2/A, do you think I need to replace anything...

Dave - Goodmans GDB18FVZS2. I'm afraid your fix didn't work.

The other sets in the house have no such message after retuning.
I'm guessing it must be a system-wide freeview message. Maybe it will disappear after today.

Those constantly getting retune messages should probably contact the box or TV's manufacturer.

I'm aware that some equipment might do this if it picks up signals from more than one transmitter. You could try doing a manual retune - unplug the aerial before doing a full reset (first time installation, factory reset, full retune, virgin mode, default setting), allow it to complete its scan (not finding anything), then manually tune in C23, C22, C28, C29, C32 and C34. If you don't have a Sky Sports subscription through BT Vision or Top-Up TV you can skip C28. If you have an HD box (and I sincerely hope this problem doesn't occur on them!) you can try tuning in C31 as well.

If your box doesn't offer manual tuning, try starting the reset process with the aerial plugged in, then unplug the aerial when it gets to about 28% through. If you can see it listing the channels found, unplug when it sees the services on Mux C (PICK TV, Dave, Really) and leave it until it completes. You can find other tips on how to handle this at Digital Region Overlap.

I did read from a poster on Digital Spy's forums that Crystal Palace was carrying service information last night for both pre-switchover Mux 1 and post-switchover BBC A. I hope that isn't the cause of the problem.

I have the same problem with the persistent update request Blue Boxes on two different
Goodmans models
GD 11 FV ZS2
However when I hooked up a Grundig box
there was no problem after retuning
just the once. I stopped using the Grundig
due to problems with aspect ratios and subtitles.
Its maybe intersting to note that both Grundig Boxes and the Bush box mentioned earlier all terminate "ZS2" - possibly this is the same softwarefirmware version as shared by all three models ?
