Hi there, I hope someone can help. My PVR9300t has just stopped working, it was in standby but I couldn’t get it to switch on. After switching it on and off at the mains it now won’t even go into standby mode, the fan comes on and I can hear some HDD noises but there is nothing on the display. I upgraded to the latest software last week and there have been no problems at all since then until now.
