Thomson DTI6300-16?

My Thomson stopped working yesterday. When I tried to power up it showed a continous flashing of red, green, red (simultaneously) with intermittent red and green flashes in the higher top left led. This is not an amber light issue and I have tried restarting it following the power off, press standby then menu and ok and the power off standby up down left right 'solutions' but all to no avail. Does anyone have any ideas?
