My 19" Accoustic Solutions lcd tv?

I have a problem with my tv, won't turn on at all although there is power to the lead as I have had that tested, no standby light on either, the power lead is not the detachable type, have tried changing fuse in the plug with no joy.

Any ideas would be great as I am so miffed as the tv is just (and I mean just) over the warrenty.
