Bush IDLCD27TV006 - Not finding Digital Channel Signals.

[Alfzammit]

Hi, I have a Bush IDLCD27TV006 that was showing 'No Signal' on various digital channels. I tested it on a known serviceable aerial connector but still had the same problem. I then reset it to manufacturer's default and did an auto scan. It did not find any channels. I'll be very greatful far any assistance.
