TV Aerial Question (Calling Bill Wright)

Nearly every day my Panasonic TV starts up with a message that there are
"new channels" available.
I allow it to scan if I have time but usually to no avail - usually I
cancel the message.

Do you know what causes the message to come on? Is it due to a drop in the
signal level during the night or is something being sent out from the
transmitter?

Its probably in the TV software and will be because you've not set it
to auto-scan when on standby or at any fixed time. At a guess if
you set it to scan at 3.00 am each day the message will disappear.
Because the TV hasn't had a chance to scan the default error message
will be "new channels available" just to be on the safe side,
even if there aren't any.

This timed autoscan option will probably be buried deep in the menus.

I have an LG DVD tuner recorder which switches itself on out of
standby at 3.00 each day, presumably to check if a rescan is necessary
And there's no option to turn this off - only set it for a
specific time while switched on.

I've owned this thing for nearly two years, but because I'm not usually
awake at 3.am I never realised this was happening.

My Panasonic DVD PVR does the same. I thought it was because the
signal is too strong but I'll have to investigate Michael Adams'
response.

It's happened to mine over the last week.

The problem is that the signal strength for some of the channels has
dropped too low for them to be picked up on the scan, so immediately
after the scan, there are still new channels available, because it
couldn't pick them up on the last scan.

This was just on some of the more obscure channels, but this morning,
it's hit BBC1, 2, and news24. They broke up so much I did a rescan
in case they changed to a different UHF channel, but now they're
gone completely, and guess what, there are new channels available!
Well they're the ones it can't currently pick up.

I presume there's some messing around with the transmitter at the
moment. Normally the signal strength for most of the channels is
high for me.

Her LG lost all it's channels for some reason yesterday. I blame
putting computers into TVs. The TVonics lost everything last week, I
reckon it's endemic.

It can also be due to the increased transmit power post digital D-day
resulting in sidelobes of your aerial picking up remote stations. Most
of Manchester is plagued with older Panasonic TVs that left to their own
devices would replace the default channels 1-5 with their Welsh language
equivalent even though aerials are pointed at Winter Hill.

You can disable the "message when new channels are found" option in the
menu and then force a manual rescan when you find something missing. It
is usually just some new fly-by-night shopping channel anyway.

The fix in Manchester is to unplug the aerial until autoscan gets past
ISTR channel 45.

This was just on some of the more obscure channels, but this morning,

Have a look in the ?800's and you may find that the good SNR channels
have been relegated up there. That is what happens on my parents set.

Disabling the message is a fairly effective fix. eg.
Setup/Tuning/New Channels

I presume there's some messing around with the transmitter at the
moment. Normally the signal strength for most of the channels is
high for me.

The problem arises when another set of channels at a lower frequency
come and go with the ebb and flow of the tides (or whatever it is). The
older sets are rather dumb and put first found rather than most
geographically local or strongest signal in the default master channels.

Thanks - message disabled now.

Google this and you find lots of people with different Panasonic kit
asking the same question over several years. At least one person
thinks its a bug in the firmware. (I turned the message off on my
PVR/DVD now.)
