HTS5131 Soundbar fault
I've a HTS 5131 Soundbar. Having returned from a long holiday it seems to of developed a fault. It was switched off when I way away. Theres no sound from it at all, but if I play a DVD it does supply sound to the TV, but not from the unit itself. I've plugged it into my wifi router and it tells me its downloaded the latest version of the software. I've unplugged all the cables and switched the unit off for a while, but its still the same.
How long are these unit guaranteed for as I'm sure it must be nearly a year old?
