Hi, am on my second tv, the 3d didn't work at all on the first. The replacement set arrived yesterday and all was fine. However when tried to switch system ( onkyo 609 and Samsung DVD) this morning there was no picture. This happened on the first set also, can't understand it, nothing has changed since day before. Cables are 1.4. On first set when this happened I tried all Hdmi sockets changed cables etc but didn't work, although the sky and DVD player and all cables worked on tv upstairs. Will need to look later on, any ideas as to what the issue may be, strange that this has happened on both tv's when they were switched on the following day. Any help/advice much appreciated.
