Getting Ch19 'Yesterday' OK here Phil, can't think of any reason as they are all high power now, unless they're doing maintenance on that mux?

Retuned several times yesterday (24th) but my BBC stations are going to 800s and sometimes the ITV/C4 ones are going there too but sometimes to the correct place. Tried a manual retune but that still plonks them in the wrong order... 19LG3000 DTV. I get all the stations just not in the correct place. I never had this problem with retuing before... Any ideas? Oh I tried a full factory reset which also didn't make any difference. Am in CB25.

Steve, can't imagine what's happening. If you do a factory reset and then a Manual tune on those channels from Sandy Heath it should clear out all the old channels and put the correct ones in the correct order.
What TV or PVR are you trying to tune?

Hi MikeG
It's an LG model number 19LG3000 which is a 19 inch digital flat screen TV. Previously everything has been fine at the periodic retunes required but not this time!

Sean Fitzgerald: I would keep the channels between 64 - 69, as modulators in most boxes work best in these ranges.
I will say though that Sky HD boxes do have a record of complaints regarding weak modulators, so keep this in mind.

Steve, regarding your LG model number 19LG3000.
I have downloaded the manual for this and strangely it seems to allow for programs to be in the 800 range, which on most units indicates duplicate TV channels have been saved.
There is a Program Swap option however which may help, but I have a suspicion that the set may need to reboot itself from scratch.
Apparently many TVs and PVRs can crash (after all it's only a computer) and unplugging them from the mains for a few minutes makes them reboot from hardware.
This can cure a myriad of problems. My Toshiba failed to recognise the remote and unplugging it cured it. Worth a try.

P.S. You need to actually unplug it; just turning it off at the set doesn't always completely isolate it.
