Samsung UE55C7000 Screen Blank

[admin_exported]

I seem to have a number of problems that I had decided to just live with which were
Backlight bleed/ torching
Some White light patches on the screen - can only see when very dark
Blinking - screen will go black for a second then back on.

Now it seems that sometimes when I switch from sd content to hd or the other way the screen will stay blank until I change the Channel and go back again, it does not happen all the time but I am becoming increasingly annoyed with this tv.

Any suggestions i have had the TV 6 months.

Have you tried turning off the any net+ or bd wise functions, I found that my 50c6900 was playing up with these HDMI handshake functions switched on.
