On Feb 9, 2:38 am, "Bill Wright" <insertmybusinessn...@xxxxxxx>I didn't investigate, but I thought at the time that it was odd that

At that
point the penny finally dropped. I pressed 'menu' 'set up' 'manual
tune' and
switched from System BG to System I. I then re-tuned every channel
so
everything was in the right order. I noticed that only presets 5 and
20 were
set to System BG. The other TV set had preset 20 only set to system
BG.
This surprises me, since all the LG LCD sets I've tuned in have auto-
detected the system of each signal they've found while scanning, and
automatically switched to system I even when BG had been manually
selected in the menus.
the first set was on BG for preset 20 (Sky box) and preset 5 (off-air
Channel Five) but not any any other preset. It can't be anything
peculiar about the signal on the satellite channel that confused the
telly because that channel came from an identical modulator to the
CCTV channels.
I never found out why the Comet man had insisted on putting the
satellite channel on preset 20 despite the customer pressing him to
put it on preset 6.
I didn't properly investigate the second LG; I just quickly retuned
it. I have a feeling that preset 5 was already on System I though.
I wonder if LGs auto detect the system on auto tune, but not on
manual. My first attempt to retune the first set was to use auto tune,
but the set made a complete mess of it. It didn't detect the channel
idents and simply assigned presets in UHF channel order. It also
failed to find the two monochrome CCTV channels.However it did find
and store the modulator for the DVD player, which was off, hence no
modulation on either the video or audio carriers.
What a contrast this is to a Sony PVR that I installed the other day.
This had separate loopthroughs for DTT and analogue; it did a full
auto tune, put all the analogues in the correct order, then tuned
every DTT signal and finally removed the DTT duplicates, explaining
exactly what it had done on screen. Magic!

Only problem is what happens if the station you want is one of the
deleted duplicates?
This lo-hi tuning has a lot to answer for, especially if as here we get
both Bilsdale (gp A) and Emley (gp B) and we want to watch the latter!
