Hello everyone, my first message here asking for any experience or help concerning this problem. Sorry that it is not exactly concerning the software, but there is no separate forum for "general functionality problems".

I got a Philips 40PFL6606H/12 two days ago, and it has a very annoying buzzing noise coming from the back of the set. The buzzing sound is audible mostly when volume is low or is muted, but it has to be at a pretty high level to cover up the noise. It is very high-pitch and can be heard throughout the living room when the TV is on low volume.

It is not from the speakers, that I have confirmed. I have a DVB-T Set Top Box as the main tv source, and the buzzing sound is there even when the STB is disconnected from SCART. When I watch the HD Demo video clip from the TV itself, the buzzing noise is there.

I have updated the firmware to the latest 000.010.094.001 (on the TV it is Q5551_0.10.94.1), nothing about the buzzing noise has changed.

Please help? What can I do to track and solve this problem?

All best.

I know that the pfl9705 have problems with different kind of buzzing noises. Some owners have reported that they have get rid of it after sending it to philips service for repair. So, if I was you I would contact philips support for help. Even so, don't keep your hopes too high, They were never able to get rid of the buzzing on my TV; I have to turn off the ambilight to make my TV quiet.

Thank you for the reply. I got my TV set in Macedonia (Skopje), and I don't see a Local Call Center. Can I call anywhere else, in Croatia or Slovenia for example?

Otherwise, I think I partially solved the problem by reseting all picture settings to factory default - I read this suggestion while searching through the internet. I had chosen a more vivid config before, and when I reset the config the buzzing noise became less loud. Nevertheless, is this normal? No sound from any TV set should be that irritating, especially when emitted throughout the watching space, no matter what the picture config is.

Any other suggestions?

All best.

My 40pfl9705 makes a high pitch buzzing noise when ambilight is on. Turning ambilight off and noise goes off. I think it is related to home power supply as I checked it at work and noise was not there. Maybe the ambilight led's are affected by noise power supplies.
