Hi Folks

My Hd1+ (Single Tuner) has recently developed a fault where all the channels are greyed out & i have an error message of "no free tune!". If i restart the GUI, everything comes back working normally however when i put the box on standby, the same error occurs. The fault only seemed to develop when i upgraded to Zeus. I had no previous backup so im unable to go back to a previous setup. Ive now flashed several different images, and the same problem occurs which leads me to think its a hardware issue. Also when the receiver is in this state, i am unable to scan for new channels with an error of "unable to start scan".
Can anyone shed any light on this?
Many Thanks
Paul
