Is it safe to put a TV on a mains timer?

Can someone advise please - will damage result if I put my Panasonic
CRT TV on a mains timer so that it switches off at 12:00 each night
and them switches on again at 7:00 in the morning?

The reason I question this is because from past experience the on/off
switch in a TV sometimes breaks the current to some parts of the
circuitry before others, i.e. it is a lot more sophisticated than a
mains timer.

Thank you

It might be safer, perhaps, but a TV should be designed for power
failures. Some TV's may not turn on after the power goes off and may
require manual intervention. Easy to check. I would imaging some
TVs having a built in timer for on off cotrol.

Sure, it's perfectly safe, though most TVs will not power on when power is
restored, you have to manually push the power button. Sony is the only
exception to this I recall.

I'm sure my CRT Toshiba automatically remembers line off.

I'm pretty sure it's safe. Manufacturers ought to be aware that line cords
are sometimes kicked loose, and that receivers therefore _should not_ be
designed to require a specific shut-down sequence, the failure of which to
be followed results in damage.

The most-likely side-effect of "pulling the cord" is the loss of settings.
The set might also "forget" it was on before power was removed, requiring a
manual turn-on.

When I found a few years ago, that VCR, sat-receiver and TV were wasting
more than 50 watts when standby, I connected all of them to a mains
timer. No problem.

I have most devices connected to outlet strips with a switch.
Sat receiver, TV, VCR, DVD-player, Tuner and Amplifier on one, computers
and monitors on others.

I never had any problem. I just expect any electronic device not to
waste energy when I turned it *off*.

there's no inherent reason why not, but how old is this tv? most made
after about the early 90s have a sleep timer at least, and some sets
especailly those designed for hotels (philips, ITT nokias) have full
alarm functions.

be sure that the timer unit has a suitable current handling capacity
(most will have, but you never know...)

if the tv is an old type with mechanical pushbuttons and no remote,
one trick a guy i know did was to wire in a relay. he connected this
to his vcr, which did have a remote and timer. so when the play button
was pressed the tv would energise, and would switch off when the tape
was ejected. so if he fell asleep in the middle of a film, the set
would not be on all night.

The reason I question this is because from past experience the on/off
switch in a TV sometimes breaks the current to some parts of the
circuitry before others, i.e. it is a lot more sophisticated than a
mains timer.

that is stand-by you are thinking of. The mains switch generally is
across the main power inlet to the set and cuts it totally.

forgot to mention - as James says, some sets ,if the power is cut,
revert to standby when it is re-applied. In my experience this is true
99% of the TVs i have come across. this is probably to prevent a
fire risk if there is a power cut when the owner is away. Last year I
saw one daewoo 14" Pal-M-N /NTSC set which had a menu option to
disable this feature.

The only things I would say in this regard is that the most common time for
a switch mode power supply to fail, is from a 'cold' start after a full
power down, and if I was going to do it, I might feel inclined to plug the
TV into a surge protector strip, which is then plugged into the timer, as it
is very possible that you could get quite substantial contact bounce /
arcing at the switch-on time, which may also put the TV's power supply under
stress.

Next year all new TV's, DVD players, Home Theater systems etc are going to
require you to push and hold the off button for 5 seconds to turn the unit
off. In 2010 all new cars manufactured for sale in the USA will also have
this feature built into the engine ignition switch requiring you to hold
the key in a spring loaded off position for 5 seconds to shut the engine
off. By 2015,this wonderful feature will be built into all household
electric lights. Its amazing how smart these designers are! I mean, I would
never even have thought of such a thing. What will they think of next?!?!

Just right for when the police reach into the window of a stolen car to stop
the engine before the little scrote who stole it, can drive off again then.
Just right for when you leave a room, and flick the light switch off as you
go past - (oh screw it, I'll just leave it on). Can't see such a barmy idea
ever making it into the public realm. Just as a matter of interest, what is
the half-arsed thinking behind this one ?

Sounds like there is going to be a lot of things left on. Great for energy
conservation.

And I still have to something about my stupid cell phone. i have
to hold the off button for over 3 secs. Way too long.

Eric's yanking yer chain, Arfa.
 
Thank you to everyone who has replied - it seems I was worrying
unnecessarily.

I think Arfa's advice is good though and will see if I can find a plug
with a surge protector in; failing that, I'll get one of those
distribution boards.
