TV buzzing when showing whites and bright colours

When watching sattelite tv on my boxy old standard sony tv i was getting a really annoying bizzing noise when the screen showed bright images or colours especially whites...i put this down to the grand old age of the set so went out and bought a brand new panasonic 50" full HD plasma set and yep you guessed it!...the noise is still there!!!... please help...could this be caused by a faulty cable or something as its affecting two totally different types of set????

    thanks for getting back to me!.. for both sets the buzzing is coming from the tv... the old set was only connected to the sattelite box via a scart lead and an xbox with standard supplied xbox cable.... the new set is still connected directly to sattelite box via the same scart cable,but the xbox is now connected to a harmon kardon AVR255 which is then connected to the tv via an hdmi cable.... i dont seem to get the buzzing even with bright whites when watching dvd's on the xbox through the AVR it is worst with bright/white pictures when watching sattelite tv.... could a fault or damage to the scart cable be causing this pesky noise?? its driving me a bit nutty considering the expense of trying to upgrade my viewing equipment!... any advice greatly appreciated and anticipated!!!

I had the same problem when I connected my new At&T cable to the tv card in my PC. I did a little internet research and found out that the problem is called "video buzz". It is where the video signal bleeds into the audio signal. I was connect via coax to the cable box. I was able to fix it on my system by "fine tuning" channel three (my TV card has this capablility). Your system may or may not have this feature. If you are connecting using the A/V input it may be something else.

Where is the sound coming from, the television or are you running some kind of audio system? What cablles are you using (eg. HDMI, Component)? I can help you a little more by knowing these things.

    If I understand correctly the TV works fine with a DVD through your HK system, but the satellite is the pest. Is it an older receiver? I would just replace the cables from the sat, then get a different receiver from who ever your provider is if the cables dont work. It sounds like the rest of your system is fine.

Sony BRAVIA KDL-40W4000


Hi there,

I've been looking into this myself as I've also recently purchased the KDL-40W4000. I was watching a murky old film and was getting a bit of sludgy ghosting but found that by reducing the contrast to 25, setting the backlight on low, colour on neutral and the brightness about 40-60 (and taking ALL advanced noise functions off), this reduced the ghosting considerably.

BUT, this is quite a cool and dark image. If you watch standard TV and films mainly, a variation of the Cinema setting is probably the best overall setting i.e.

backlight: min
contrast: 79
brightness: 50
colour: 53
colour temp: Warm 2 (although Warm 1 is less yellow and still fine)
sharpness: min
noise reduction: off
mpeg nr: off
contrast enhancer: off
colour space: standard

Lost color, loud buzzing sound HLP4663W


This can be the colour wheel assembly, or the servo drive board, or a fault on the circuit board that does the sync processing for the colour wheel.

You will have to have the set properly serviced.
