V8-902 Post Software Update Problem

[dave197456]

I have just updated the software for my KD-55XE7073 from V8.764 to V8.902. I did this via USB as the auto update would not find the new update.

Although it has fixed my Wifi issues it has made my picture fuzzy and everything is out of focus. I have tried altering the settings and even resetting but to no avail!

Please help
