I think I've cracked this one,went on Tosh web site found firmware,uploaded via usb socket,switched set off for thirty minutes & back on,stations still there.Very odd set though,at sw on Toshiba comes up in big red letters,then blank screen for quite a few seconds,then stations come on.If you try to excess smart or customer controls too soon,message along bottom of screen say's system loading & a percentage figure.Very odd.Tried set after being off all night,came straight on.
