Stopped working whern mains unplugged and then replugged?

Panasonic DMR-EZ24EB. This worked perfecrtly for two years or more, but when I moved it elsewhere and powered it up, it just keeps saying 'please wait'. I assume it's something within the PSU that has gradually deteriorated and on unplug/replug then refuses to work. It's a good machine and I'm loth to have to change it
