Bizarre digital TV signal anomaly...

Posted by: Mike Dudley on 26 April 2009

All the usual effects - pixilation, frozen picture, no audio, out of step audio & picture.

All the standard responses - see if the neighbours have it (no), re-install all the stations, unplug everything for 10 minutes. No result.

The anomaly is that THIS ALWAYS HAPPENS AT 8:07pm EVERY EVENING ON THE DOT. The rest of the day, everything's perfect.

There's no signal testing going on at the transmitter (Crystal Palace). There's nothing coming on indoors that wasn't there before (there's only the fridge anyway).

Short of an exorcism for invisible gremlins, I'm at a loss... Anybody else had this, or got any ideas?

Is the 8 07 time consistent through out the year?
If not is it related to the time the street lights are switching on.

What elses is happening in the house, neighbourhood at 8:07?
Posted on: 27 April 2009 by Mike Dudley
It's been happening for about three weeks, so the streetlights are not the problem (nice try, though...). The neighbours are not having the same problem. Nothing has changed inside the house or in the adjacent properties.

Weird, huh?

If you do nothing how long does it take to stabilise.

Have you switched off all other devices in the house including central heating just before the key time to see if the problem persists.

Stabalisation - well, I was up at about 02:30 the other morning and it had stopped, but it's still going when I hobble up the wooden hills at about 11pm...

Mike

Is it a Freeview box? If so, could you take it to another location (friend/nieghbour/relative) to ensure that it's nothing to do with the box?

Similarly, could you borrow another box to see if that is impacted in the same way?

Once you've ruled out the box, you'd at least be down to just looking for 'other factors'.

(Are any of the family being abducted by (punctual) aliens on a nightly basis?)

I have no idea what else it might be. Sorry.

It'd be interesting to see if it stabilised at the same time every night (although a complete pain to find out). Perhaps you could record the affected signal from 8pm each night - then you could fast forward to work out when it finished.

Mike,

If possible check two houses up the street and two down as it could be a problem on the shared electrical phase.

I had a flicking light problem that was traced to a workshop striking an arc on an arc-welder some years ago.

"What’s He Building?

What’s he building in there?
What the hell is he building
In there?
He has subscriptions to those
Magazines... he never
Waves when he goes by
He’s hiding something from
The rest of us... he’s all
To himself... I think I know
Why... he took down the
Tire swing from the peppertree
He has no children of his
Own you see... he has no dog
And he has no friends and
His lawn is dying... and
What about all those packages
He sends. what’s he building in there?
With that hook light
On the stairs. what’s he building
In there... I’ll tell you one thing
He’s not building a playhouse for
The children what’s he building
In there?

Now what’s that sound from under the door?
He’s pounding nails into a
Hardwood floor... and i
Swear to God I heard someone
Moaning low... and I keep
Seeing the blue light of a
T.v. show...
He has a router
And a table saw... and you
Won’t believe what mr. sticha saw
There’s poison underneath the sink
Of course... but there’s also
Enough formaldehyde to choke
A horse... what’s he building
In there. what the hell is he
Building in there? I heard he
Has an ex-wife in some place
Called mayors income, tennessee
And he used to have a
Consulting business in indonesia...
But what is he building in there?
What the hell is building in there?

He has no friends
But he gets a lot of mail
I’ll bet he spent a little
Time in jail...
I heard he was up on the
Roof last night
Signaling with a flashlight
And what’s that tune he’s
Always whistling...
What’s he building in there?
What’s he building in there?

We have a right to know..."

Last night the problem logged in as usual at the usual time, but it seemed less severe...

The local home-built phase morphing dimension conjudicator is nearly ready.

The Naim theme tune

I heard that the other week on the radio. Quality.

Well, replaced the analogue aerial with a quality digital aerial and pukka cable. Hasn't made any difference.
I admit defeat. All I can do now is hope that it will eventually disappear of it's own accord in a reverse of the way it first appeared two months ago.
