It looks like a power supply problem to a specific group of LED lights in that corner of the screen. I'm no expert, but that should be repairable, and for a lot less than replacing the actual backlighting. The lights themselves are probably fine. Check with dealer.

Good evening,
Looks like it is half of a row of LEDs used in the backlight system that intermittently stop lighting. The source of the problem may be a bad connection, a cold solder joint, or the chip used to address the individual LEDs. Unfortunately, a job for a technician.
Good luck,
Jean
Thanks everybody. I'll get a technician next week.
I am not sure if the BV7 is back lit or edge lit. but it looks to me like one of the led lights is.has failed. It should be repairable but as to cost, I have no idea.
I suggested the led as a similar thing happened to an iMac i had.
Hopefully it should not cost too much
I'm not sure if it's s light failure aso the fault isn't currently displaying itself.

Please keep us posted as to what the technician tells you. I have the same BV7-55 mk2 and absolutely dread having anything bad happen to it.
My parents had a cheap, 40 inch Vizio LED backlit TV that started showing a dimly lit bar at its center. After doing research, I discovered that it was a known issue caused by a failing power supply which caused a row of LEDs to stop lighting. Some users reported flickering as well. In those cases, the indication was that the repair to such a TV would be around $200-$300 to replace the LED power supply, but because those televisions cost $200-$300 new, it made more sense to just replace the entire television.
In your case, I'm sure that a $300 repair bill to rid yourself of this problem would be a great relief. Hopefully it's nothing more serious than that.
Good luck, and please report your outcome to us here.

The BV7-55 has a demo mode for the micro dimming system.
Almost 1000 LEDs @ work in 512 zones, pretty cool actually!

It should make it easy for you to spot the issue. Unfortunately, I can't recall how it's invoked, but I am sure someone here does?
Could be a software glitch. Get the engineer to hook up his laptop and buzz the latest SW into it first...

Just as an update.
I have fitted a new HDMI cable from our Sky box, where most of the interference came from. After two days not one hint of a fault.
The curious thing is that Apple TV would suffer from the shadow but much less, and if I went from Sky to built in DVD, it would still exist but then rapidly disappear. I can only assume as an amateur, that the Sky HDMI cable was causing some kind of static that also affected the Apple TV next to it, and the DVD player cable next to that!
I have read that one HDMI cable is as good as another, but this has worked well, and the wife is convinced the picture is better.
