Hi, I recently bought a Dbox 2 and it's been working great for the last few days, now all of a sudden it only shows digital radio when you switch it on and it then switches itself off to standby mode in a minute of being on. I have unplugged it from the mains and switched it back up but still the same, goes to the radio station stays there for about a minute and then switches itself off to standby. I have tried to press the dbox button and have tried all the colour buttons but they don't do anything. I can't re-image it because it only stays on for about a minute. Please can you help?
