original vu+ Duo won't stat up

Hi all,

I have an original vu+duo for past few years (not a clone)

I've always used open pli as the image

I did the on line update yesterday

last night I put the box into standby, which I do everynight

this morning I switch box on and can only get sound

I switched off at back, restarted box

and all I get is the red light , the hard drive boots up and nothing else

I've disconnected power and still no life

any ideas please

thanks

Johnny
