Hello everyone! Four times in the last couple of weeks, my V+ box has frozen while on standby. The clock has locked displaying - presumably - the time that it stopped working, and the box doesn't respond to buttons on the unit or on the remote. The only way to get it going has been to power it off and back on. It's never happened while the box has been switched on, only when it has been on standby. As it's an intermittent fault, is there anything I can try before asking for someone to come and have a look?
