In the dark recesses of my brain is a fragment of memory regarding a
customer complaining of something similar to me decades ago.

One incident I do remember vividly was the woman who put a call in for
me to clean the inside of her screen. You will recall that sets used to
have a removable glass screen that got mucky inside as did the tube
faceplate, so it was a reasonable request. This set however wasn't of
that type, it was a colour set with the modern "push through"
presentation of the CRT.

I explained to her that it is quite impossible for dirt to accumulate on
the inside, and in any case it looked perfectly clean. She still
insisted, and opened the curtains wide to let the direct sunlight strike
the screen, and only then could I see some barley perceptible streaking
on the glass from whatever she was cleaning it with.
I told her that was on he outside, she insisted it wasn't.

At my request she brought me a damp cloth with a drop of washing up
liquid on it, and like all good demonstrations, I just cleaned and
polished one half for comparison.

I was totally unprepared for what came next.
She turfed me out saying "So you're saying my house is dirty?"

The correct answer is, no, maybe this tv has a larger than usual attriction
for dirt.
Not being able to see the picture mentioned, if its a flat screen then I
have no idedea, but I do recall some sets having a kind of less than uniform
antoi reflective coating which could eventually become detatched but usually
in blobs,, but I suppose if someone rubbed it in one place it could have
that sort of effect.
The set I had was made by Sharp I seem to recall.
I bet there are lots of interesting things in store over the years for
plasma and lcd screens....

What's really odd is that the lines continue across the screen surround, and
even onto the loudspeaker thing above.

Obviously severe EM interference from the solar luminosity control device.
Suggest manual adjustment of the bi-directional control cords.

It's certainly true that when plasma screens are used to display content
with a high degree of static content the burn-in is not always
recognisable as text or graphics and just looks like dirty streaks.
I often see such screens in motorway service stations.

The picture Bill posted is just of a small Sony wide-screen LCD with
diagonal stripes protected from a window with a nearly closed Venetian
Blind. I suppose he took the picture because it is slightly reminiscent
of herringbone CCI.

Of course, the Venetian Blind analogy is a common one for technicians
and engineers involved with the Phase Alternating Line encoding system.

memory says these were called Hanover Bars. Venetian Blinds came from
co-channel interference.

Herring bone interference was usually some other source.

Stop the presses, wrong city.
It's Hanover bars isn't? I must be getting old.
Anyone know where the expression comes from? Google just gives me
nightclubs in Germany, New Hampshire and Pennsylvania.

guessing that's where the Telefunken* research labs were based.

* they were the ones who develped PAL, weren't they?

Over the years? My original LCD has a better picture than modern ones.
It's a Lloytron. Some people see the picture and ask if it's HD?

That'll be people who've never seen HD I suppose.
