Purchased 14 months ago and it suddenly "died". No screen, no audio. After switching off and leaving 1hr, switched back on and worked. One day later, after switching on for about 1hr it died again.
It's 2 months out of warranty and going to cost heaps to have a technician come to have a look at it.
Has anyone else had the same problem?
