Thank you for your prompt response. I was hoping to try out the solutions mentioned by you, but now all I get is the White Screen of Death when I switch it on. I'm taking it to the dealer today as there is a technician out there.
I did try re-opening the unit and wiggling the wires. My unit is only 8 months old, the U106 attached in. Since it's under warranty, I'll give that route a try.
