Hi my Samsung 50" plasma tv has this rather annoying high pitched whine sound even on standby. on soft tv volume this noise can still be heard. my warranty is about to expire so kinda need to know if it needs attention or just a 'normal' annoyance.

thanks!

Complain to the supplier about it anyway, they'll know if theyve had others with same issue and what happened to those.... else theyll tell you to take it in under the warranty anyway :)

hmm - so do you guys have a plasma tv? does it not make any noise (it's really really really high pitched even on standby - the only way to get rid of it is to unplug the mains)? hmm

Our Samsung LCD did this when on standby. It was under warranty and a repair person came out to the house diagnosed it, and returned within a week (if I recall correctly) to replace the powersupply in it. Problem solved.

I had a plasma (panasonic) that did this. I think it is a feature of plasmas maybe?

The sales guys don't mention this in the shop though.

I've got a G10 Panasonic plasma - There is a cooling fan in the back - You can only just hear it when you mute the TV - But I wouldnt say its anything like "a rather annoying high pitched whine". And the fan stops as soon as the TV is turned off - no noise at all when switched off - silent.

Apparently most plasmas do have a cooling fan somewhere - Someone told me there is one brand that doesnt - but cant recall what it was.

I have however noticed that my Freeview STB is making a high pitched noise when turned off - only does it sometimes - but it is in the bedroom - tend to just leave that turned on to keep it quiet

My previous TV was a Pioneer Plasma and my current one is a Samsung Plasma , neither have made a noise like this.
I have many friends and family with plasma TV and have not experienced similar when visiting any of them. I would suggest you have a problem with your unit.

Most plasmas should have some kind of cooling fan but most aren't a nuisance.
I visit AVS forums occasionally and there are several dedicated threads to this issue with quite a few samsung plasma owners having the same problem, go check that out if you want some more info. They're mainly from US owners but I think the models are the same.

Sounds like a faulty power supply to me. Just my $0.02.

hi, did the tv make your ears ring? my ears are ringing and i'm not sure if it's the tv or not. also is repairman covered under warranty and should i expect to pay their fee to come out?

Hi joker97. The high pitched noise in ours was high enough frequency for some people not to hear it I am guessing. Not too unlike the sound of a camera flash charging, but quieter and without the ramping up of the frequency. I found that it really got into my head. Ours was covered by the warranty - no charge. But I guess it could be subjective since the TV is working.

Our TV was not that old when the problem occurred.

the peace and quiet lasted about 24-48 hours! the whine is back! i'm just going to guess that it's fairly normal for samsung panels to do that. (plus google to assist of course). :(
