    I have read a few notes about the buzzing sound from the Sony sets.
    I posted a question to Sony about the noise. Here is there response which I think is a valid one, allthough I have a set which doesn't make that much of a buzz. I think some sets may be worse than others.

    "Most CRT based televisions do make a low level buzzing noise, which is
    attributed to resonance of the scan coils. The effect is worse on 100Hz
    models because the higher scanning frequency is easier to hear. This is a
    known characteristic of 100Hz televisions due to the technology employed and
    is therefore not a "fault".

    It is generally not loud and therefore is not usually noticeable in normal
    viewing conditions. However, in a quiet room it may be evident and the
    intensity may vary from set to set. Having said this, we do acknowledge
    that to offer a diagnosis by correspondence is not possible and therefore,
    if you feel the television is not working to Sony specification, we would
    recommend that it is inspected by an authorised service engineer who will
    be able to give you an informed opinion based on their examination.

    So, they answer very clear,
    If you want a TV that buzzs, you must buy a Sony one.
    If the buzz annoys you, you would better look for another brand.
    If don't, When you say them your tv buzzs they can say is under Sony tolerance, so...no problem at all.

    I just think it a pot of luck.

    As I have got a sony KV32FX66 today and I and few other mates who got very good hearing cant hear the buzz when watching tv and when it muted even standing in front of tv. But the only time we can hear is if we have our ears right against the plastic on the back then again it is very very low

    I am happy i got one that dont buzz

    What settings have you adjust if it picture settings what have you got them at?

    Also have you got Sky digital on yours if so how you get it set up? ie RBG or???

    Also have you watch football on yours yet on sky that if you have? if so do you notice that it is good when cam on the players and just the pitch. But if the cam zoom out getting sponser board on and fans you see a bit of flicker in those area not on the pitch or players. This what I have notice and been told it common problem with sports

    I've just had a replacement delivered from JL - it buzzed worse than the original.

    I'm not sure what to do now. I gave it nearly two weeks and the buzzing didn't improve.

    Do I try and get another. I don't know why they don't test these things before they deliver them. The JL engineer said as much. I don't think he'll be keen to carry another up the steep slope to our house.

    Because of the way we have our living room, the back/side of the TV that buzzes faces the dining table. It is quite distracting, even at higher than normal listening levels...

    I just cant understand how some people get tv set that buzz like hell. Some that buzz a bit and dont bother them. And some like mine in which you cant hear it buzz at all even with mute on. only time you will here a buzz on mine if you put your ears right against the plastic and listen hard and that sound is very low

    Hi

    Who cares about the buzzing. I've had this set for a week and it has just gone back due to its obvious colour-misalignment fault.

    The company I bought it off brought a replacement to my door, and when plugged in it had the exact same fault. If you look along coloured boxes, or anything with a sharp edge, you'll notice the lower 1/8th of an inch has no colour, while the colour goes 1/8th of an inch above it. It's as if the colour signal isn't being placed back ontop of the black and white below it.

    Sure it looks great as a whole, but frankly its unacceptable for a TV of £950+.

    I'm off to go looking at TV's tomorrow. Can anyone suggest one for my perfect eye? My budget is £950. I'm not after Pro Logic as I use an amp, and am after a stand and case which doesn't look like a dogs face thats chewing a wasp - finally I wish it to be 100" and 32 inches.

    On a last note, I'm surprised you care this much about a buzzing that you have to get your head behind the TV to hear - surely you lot buying TV's of this "quality" are going to be cranking the volume on your high quality DVD's.

    A TV is for watching.

    The reason why I am saying I can only hear a very low buzz when i put my ear right against the tv is to give people the idea how loud it is.

    I bough it for the quailty and am happy with my set.

    As you will have read alot pf people can hear theirs buzz even if the volume is on .

    what you are describing are "convergence problems" - when the three colours that make up the picture (red, green, blue) don't quite hit the screen in the same place. Unfortunately, the bigger the tube, the more difficult it is to get them all lined up. I've yet to see a big widescreen set without at least minor convergence issues. This is not peculiar to any particular manufacturer (and is possible to fix, or improve, via service menus - but is a tricky and laborious procedure, even for a qualified engineer). If it is VERY noticable - then it's a fault and you should be able to get a better set "out of the box". Whatever set you buy will probably have at least a slight problem somewhere on screen - it depends how tolerant you are. I agree for that sort of money you might expect perfection - but sometimes the precise bending of electrons is beyond even the most expensive set.

    naa its not convergance mate... The colour image is perfect, just not ontop of the b&w.

    anyone with this tv shove on a high quality dvd, and flick the tv modes until you can see a couple of black borders at the top and bottom...

    look at the bottom bit of the image and let me know if you see a perfect black&white image... very thin though - and colour for the rest

    FYI:

    So after my long wait to get this problem solved they eventually fixed it.

    Apparantly they needed to replace the "F-board"; a power supply board on the lower right of the TV (facing from the front screen). A component on this board is at fault.

    Sony came and fixed it in front of me - taking around 20mins.

    Now no buzz, only a very slight hum (as expected of all power units) not noticable unless you REALLY listen for it in silence!

    GGrrreat!

    Matt.

    Didn't write down the part number by any chance did you??

    I think I might be ringing my local dealer about my "F-board".

    Sorry, I didn't get the p/n. Sony suggested that just the faulty part be replaced and soldered, but the Sony engineer wanted to just replace the whole board - so he got the part and replaced it.

    I think the faulty part is called the power factor coil.

    Hope this helps.

    Matt.

    This was for the FS76; although I'm sure it applies to most Sony TVs.
