I have bought brand new Hisense 40 3d fhd led tv but no power.How can I switch it on?

Your Yamaha is the problem here. It cannot handle the signal and process the 3D as it states. What I would do is hook your player direct to your TV in the manner that it works and feed your audio from a different path to maintain surround system. Your tv/dvd player may have an audio out that you can feed back to the Yamaha .

did you ever fix this?

You can send me an email to [email protected] and I will send it to you. Please put "LG HR598D" as the subject or you can use the web address below.

U also must have a LED 3D tv for the 3D DVD movie play on a Blu-ray player to play to get for the 3D movie effect.U now that wright?

So far no solutions to this!
One thing with bluray though is they changed the regions from DVD. Not sure where you are but her in Aus we are now region 2 sharing with europe. hooray!

this software in my own experience is not very user friendly. I recommend getting on a torrent site and trying different DVD software instead actually. Unless you purchased a key, then click on help, and there you should be able to enter your key code to activate in the 'About' section or Register.
