TV speaker interference

[TameScrapman]

Bought one of these TVs about 6 months ago,

I have a problem where there is a high pitched buzzing sound from the speakers which seems to get louder when the colours on the screen are brighter or you are in one of the text menus. I could probably live with it but it does get annoying at times when the volume is turned up. Does anyone have any ideas what could be causing this? Is it worth buying some external speakers or would this not cure it? Any ideas appreciated.


Edited for grammar.

as a rule todays TV speakers are C.R.A.P. External speakers might help (do you have audio out? but the source of the problem my be interference in the sound circuit rather than the speakers themselves. In which case this may not help. The alternative route would be to get a cheap/second hand AV Receiver to take the tv audio circuits out of the loop - but you are talking a few hundred quid probably even second hand for receiver and speakers

Are you sure its from the speakers?

My olf Tosh TV used to have a buzz from the power supply. Bloody annoying.

Loads of modern TVs do this. Like said above it's often the power supply.

Does it do it on the headphone out? If so then connecting external speakers should cure it. A pair of PC speakers will do fine.

I have a panasonic 58". When watching at night the bright screen buzz is very annoying its a power supply in my case and is well known
