Hi Guys, UK based newbie here looking for a little help.

I have a Philips 32PF5520D LCD HD TV and recently i have lost all the sound from the onboard speakers.
The picture is fine. I have retuned the digital setup and it all looks fine, but no sound still. Using the remote and the physical buttons on the side of the TV, the volume control appears to increase and decrease, but still cant hear anything.

I haven't tried any external speakers/Headphones yet, and will give that a go next.
In the meantime if anyone has any suggestions or advice, it would be gratefully received.

Thanks and regards,
Cheers,
Brian
