Hi all....I'm smoggy from the Teesside area and I'm after some help

I have a Venton 2 Box which has the vix image on from when I bought the box from W.O.S in June 2013
The box has worked ok until today when I came in the box was in booting mode with tv screen blank
all attempts to reboot have failed
I have also tried to reflash with my original back up image using 2 different reformatted usb's in each rear usb slot without any joy, the usb lights up for a second then goes dead
Maybe trying to flash with a new Vix image will work, can anyone tell me what the latest Vix image is for my box or have any idea what the problem could be

Thanks in advance ... smoggy
