I am having a white dot/flickering problem!
Blu Ray input works fine, no problems. Roku linked up with Netflix etc - but I get white dots and flickering, not all the time but some of the time. If I unlpug the HDMI and re insert then I have enough time to watch a film. With Sky, I am now only connected by the optical as I couldn't watch much at all - the HDMI for that goes straight into the TV. Have tried new cables on Sky and the Roku - still the same :(
Anyone got any ideas? I emailed Onkyo on 4th November 2012 but never heard back - have just emailed them again today, just to try again!

Thanks for your help!!!
