Hi All

I have a  JCMatthew DVR320t that isnt behaving properly.

Started out OK I could watch freeview record and playback shows 


Now I am unable to view anything The display on the front panel just shows BOOT 

the Plasma (which works fine via it built in HD decoder) displays a green screen and static noise 

I have tried different HDMI ports (no luck)
I have tried setting up composite (no Luck)
Tried HDMI cables I know work from another set  (no luck)


Is there anyone out there that may have a solution or should I trash it and purchase another STB


Thanks in Advance
