I've had a quick search through the forums and couldn't immediately see anything that matched my issue, so apologies if this is something that has already been discussed.
My issue is around receiving freeview hd on my 40nx803. I am running the latest firmware (according to the online update option on the tv) and have a good signal using the built in tuner on all other (non hd) channels. Even the HD channels are showing need 100% on signal strength and quality, however they appear heavily pixilated and after some time they show with a message along the lines of "this channel cannot be decoded".
Interestingly I have managed to receive freeview HD on this set with all the same settings and cables.
Now comes the interesting bit, after a bit of messing about it 'seems' (and this is by no means a proven theory) that I can get HD when the TV comes out of standby on a HD channel, but NOT when I start on a non HD channel then change up.
This weekend I picked up a Humax HDR-FOX T2 and can use that to receive HD signals even when the TV is showing the pixilated picture. Turn the TV to a HD channel and then off for 10 minutes, then back on and it's all good.
Anyone else ever seen anything like this, or can give me anything to try?
