BBC HD picture dropout

I am experiencing frequent picture drop-outs (i.e. black screens lasting about 1- seconds) while watching BBC HD on a Toshiba WL768 TV. The sound is fine. Is there a firmware upgrade or anything else that can solve this issue please? I am aware of sound drop-outs with BBC HD and Sony TVs.
Thanks!

Hey,
Do you notice the same issue with other HD channels or only BBC HD?
You didn’t post the full TV model but you can search for firmware updates yourself here:

Last week, I bought a Toshiba 37RL853B Freeview HD TV. Generally the picture and sound quality are really good. However, on BBC HD, there are frequent (what appear to be) drop outs lasting a fraction of a second and these are becoming irritating. I have a brand new high-gain aerial and the HD quality is otherwise very good.
Do I have a faulty set, or is there some other reason for this?
Any advice would be appreciated,
Bill

I believe I have exactly the same problem for a year on my 46WL768 while running from a computer via HDMI.
The issue seems to be related to the bright/dark level of the input signal which happens much more often from a computer source but seems to be the same issue as you are describing.
I have tried every firmware version I can find.
I have tried, as far as I know, every combination of every setting including turnng every option off in every TV mode (something still stays on internally that controls this though, no matter what you do).
I have tried multiple computers, and multiple very expensive graphics cards.
I have even sent te set in for repair where a number of parts, including the mainboard were replaced (as a precaution because they could not find the same issue, yet I can replicate it instantly).
You can make it less annoying by switching to one of the default Hollywood display modes, but you cannot, in my experience, get rid of it. Your only two options appear to be to have it blinking constantly with a high response level to actions on screen, or to have it trip over less often but have a "laggy" screen image. If you are watching TV/non-action movies, the second option isn't too bad but it's unacceptable for computer use which is what I use it for.
The problem, as I understand it, is once the dark/bright ratio of the image being displayed on the screen goes over/under a certain trigger-level, the screen blinks over to another sub-display mode and the blank you are seeing is that switch.
