had a 9150t just over two years (so out of warranty) 😥

A couple of days ago it reset / rebooted a couple of times, then I was unable to access hard drive, view of make recordings. I switched it off at the back and on again, it went through the initialising ok, but then no picture. Repeated this a few times, could get channels maybe 1 attempt out of 10, but still no hard drive access. Left it unplugged overnight, now doesnt come on at all, no led, no noise nothing. Lastest software installed. Any help much appreciated folks?….
