Freeview blowing crt sets ?
 

I have a Sony crt about 15 years old which conked out whilst watching
freeview. Internal fuse o.k., but no on light comes on - dead.
Connected a Sharp 21"crt set - worked fine on analogue. Switch on freeview
and after a minute or so the set turns itself off ! sometimes to standby,
sometimes completely off !
Switch back on and with freeview turns itself off again.
Sat back and thought a moment. Wondered if freeview causes excessively high
voltages/current to tube. I reduced the contrast slightly and now it works
fine !
Could the freeview have blown the original Sony set ? If so how many crt
sets around are being blown by freeview boxes ?
Of course I could buy a new set, but cannot live with the poor quality of
lcd or plasma and crt sets now are scarce. Waiting to see if oled any
better.

Any thoughts on this strange phenomena from engineering types ?

Well yes, and no. It depends how you want to look at it.
It may well be the case that the peak white delivered from
the Freeview box was higher than the TV was used to from
terrestrial analogue reception from its own tuner, the box would
bypass the TVs tuner if connected via SCART, and the
contrast may well have been slightly different to the tuner, and
different again depending whether RGB or composite was selected.

But to say that Freeview killed my TV is a little unfair, it could just
as well have been a VCR, DVD or games console.
The beam current in a CRT "should" be automatically limited to a safe value.
Looks like your Sharp was really protecting itself.
In short, don't blame the Freeview box, blame the TV, or yourself
for setting the contrast too high ;-)

Yes it's a well-known problem due to the friction in the cables from
digital signals.
To avoid the risk of fire you should stand the set in a fish-tank full
of water and view the screen through the side.

Hi, I had a similar problem, your advice has been invaluable in solving
it.

Would you please be good enough to forward me your contact details as
matron, the fire officer and the insurance Co would all like a word.

Yes, it's a conspiracy theory, but not a very good one as it offers no
explanation whatsoever, not even a bad one, as to how a Freeview box is
supposed to kill a TV set. Even the one about the false moon-landings included
a few details - wrong, as it happened, but at least it was an attempt to make
the nonsense believable. You'll have to do better than this.

Well, I cannot see it myself. II mean, most tv designs are not going togo
wrong no matter how dynamic the pictures are..

More likely the sets were on last legs to start with.
I suppose one could invoke some kind of weird voltage through the
interconnects, but it would be strange if two different models had the same
vulnerability.

Dear Bill,
I am glad to have helped with your problem.
Please tell the matron and the other staff that they do not need to
thank me personally, your own response is quite sufficient.

PS Do you have a vacancy there for my friend Jamie?

Provided he does not wish to watch TV for a while he would be most
welcome.
