    Folks,

    I've had my set for nearly a whole year without any issues - glorious picture and it still has a glorious picture but now it just suddenly, after a 2 week break away, started to hum - and hum badly.

    What has been the fix for this to date? - I will be contacted SAGEM as it's still well within the so called 3 year warrenty period.

    Has anybody done their own DIY fix of some kind??

    Regards

    Chris

    Hi.
    Have you tried moving the set, to see if that lessens the vibrations/humming noise?

    Could try cleaning the vents and air ducts and see if that reduces the fans spinning speed. If the fans speed is regulated by the temperature of the set then this may work.

    Have mine on a wooden cabinet so the resonating didnt help. Tried putting a small piece of cardboard under base to distort it and that helped a bit but the whole thing now sits on some bubble wrap cut to size and completely invisible. Only audible now when muted and room silent.

    Noise can come from different sources with this set. If its the 'wobbulator' (mine is) then the sound abruptly starts during startup and has a fixed frequency. I havent heard the fan noise but that should (I guess) fade in and change frequency as it does so.

    Posted before on a similar thread to this , Im certain mine is the fan. When the TV starts up there is a faint hum ,which Im sure is the Wobulator .Then a few seconds later is a louder humming which gets a bit louder the longer the set is on, , surely this is the fan?Likewise ,switching the set off the louder hum takes quite a while to stop. Is this the same symptoms as yours?

    Cheers folks.

    I await for a replacement reciept off Comet so I can get the SAGEM folk in to look at it.

    Hum is only there when the set is on - not in standby - and it does seem to stay at a constant level.

    I may try the bubble wrap idea - or some of that foam stuff often used in packaging as I have some of that lying round in the garage, until Mr SAGEM has fixed it - if he can.

    As I said mine has not made any hum until recently, many months from purchase :-(

    Reading the thread you sent me it seems mine is the "wobulator" thing - stops instantly I go into standby and only starts when the set is up and running.

    Surely somebody had had a go at dismantling the sod and doing something - what does SAGEM do.

    Basically 11 months hum free and now humming - surely soemthing has come loose???

    My sets humming started gradually increasing over a year
    I wasn't 100% at first but it increasingly started to irritate me
    So I called Comet to send an engineer out
    I was convinced the wobulater was on the way out
    So I was all set for a big fight with Comet.
    The engineer came stuck is hear to the set did a 360 round the set, then got his screw driver out and silence!!
    I was gobsmacked!
    I had to know what it was so he showed me
    If you take the cover off the right hand side you can see a small fan
    A wire was catching on it, he pushed it out the way and wedged it away from the fan

    Took him all of 5 minutes

    Just goes to show the hum could be anything.
    The sets quieter than it's ever been now.
    Just got to quieten the the SkyHD box and the PS3 now :rolleyes:

    The wobulator fix involves taking the whole set to pieces and loosening a couple of screws on the actual wobulator
