Have you tried disconnecting everything from the TV and then unplugging it from the mains to depower for a few minutes?

I have the same problem I bought it two days ago. 

Please let me know if there is any way to solve this annoying problem.

I think my TV has the same problem.  Bought the KD-48A9 a couple of weeks ago, white flash appears in top left-hand corner.  Informed retailer and TV replaced today.  Same fault.  Did you manage to resolve the problem?

Mine the whole screen. Is only for a sec. Like cameras flash. Still got it tho. Try the other tv app . Not the youview one the other

Thank you so much for getting back.  I am not watching through the YouView app and it is also happening when watching Sky through HDMI.  I will notify the retailer tomorrow.  Thanks again.
