    when i switch my tosh 46wm48 into standby i cant hear the cooling fan which is supposed to continue running [i think?] to cool the lamp down ,the lamp is set to low power ,would this be the reason or have i got a fault?
    i used to have a sammy sp46i3hx and the fan could be easily be heard
    for a few minutes after shutdown

    Under the function menu there is an option called "Quick Start" if this is On then the fan should remain on for about five minutes (I think) to keep the bulb ready in case you decide to turn the TV on again. I can here this when the TV is in stand by - its a lot like the fan in a PC.

    The fan is left on for a few minutes to cool the bulb and prevent it from damage. It should be listed in your manual some where.

    My 52mw48 is the same - no fan at all when not in quick start. I also read elsewhere that it is actually better for the lamp to let it cool naturally instead of forced cooling. I would imagine Toshiba would have set the TV to have the fan running for cooling purposes if it was necessary.

    When you switch it off the lamp doesn't just shut down. You will notice that the screen is slightly illuminated, only a few watts and five minutes. I assume this also also allows the lamp to cool at a lower rate.

    I've turned quick start off and now my TV goes deadly silent when I switch it off. The screen stays dim lit and the fan remains on when quick start is switch on. The manual is very light on detail but reading between the lines this sounds normal according to its description.

    Also sorry for mixing my bulb/lamp terminology!
