    Should plasma screens be left on standby or switched off overnight or when not being watched for long periods ? Is there any evidence that this affects the life of the screen or doesn't it matter ?

    I was told by a tv engineer once that for long periods of time a tv should be turned off at the switch as the psu will wear out quicker on standby. I dont know how true this is though

    Did he not comment on the many Sony or Grundig front panel on /off switches he had to change and use higher melting point solder that this was a problem? or the fact that modern front panel switches are mechanically very poor ? did you ever wonder why sony set made a wrrrrmmmpf sound when turned on ?(because they lacked a simple capacitor over the on/off switch to prevent arcing and damaging the switch? )did he tell you that as costs have been driven down that minimalist engineering is common place? and did he explain that designs that would have been laughed at in the old days now "work" because they last the expected warranty period?
    well us old timers will tell you its a fact thats why your parents sets lasted 20 years now they dont

    I would say if you want your plasma to be reliable leave it on standby.
    If you love the enviroment turn it off.
    i'm expecting a big backlash but thats what experience has taught me

    I was always under the impression the Sony's made the wrrrrmmmmpf sound because that was the noise the degausser made on the Trinitron tubes, very curious to know if thats true.

    Ask all the engineers who replaced numerous parts in many power supplies and many switches with higher than normal melting point solder on a few on off switches from lots of manufacturers.
    I used to manage a service department (i am not an engineer) and have seen first hand the difference in build quality over the years .Older people used to un plug and switch off sets then the public got progressively bone idled now we press to standby and the quality of the switches reflect that.I seriously doubt that the cheap modern switches would cope with a proper on off say 4 times a day .
    I would love to switch off all my appliances but because of cost cutting i really dont think that modern switches are up to the task.and now because of the throw away society there are fewer real TV engineers who can fix to component level and replace just a switch

    You can always use the plug switch to save wear and tear on the TV switch and the environment?


    The "Vrrrmmm" noise is the degaussing coil and that it a terrific current. You are right about underrated switches though and the lack of a spark quenching capacitor.

    Thanks for the replies, seems like the concensus is to leave it on standby. When it's on standby, is the whole unit powered down except for the red light ?

    i did think about the standby issue myself.

    Quite happy to leave it in standby providing my electricity bill doesnt shoot up. think in standby it takes up 0.8 watts

    Is that good or bad?

    For one item 0.8W is not a lot but add the Sky box, video, DVD, microwave,computer,printer, router,cordless phone, receiver, alarm clock, electric toothbrush.... etc etc

    According to the Hitachi website, they say that leaving the TV on standby does not shorten its life. The power supply used for standby power is usually a different one to the one which powers the TV in normal use.
