Brand new Sony Bravia KDL-32CX520 LCD TV.
Picture is fine when watching analog TV or when looking at the internet.
When watching terrestrial UHF digital freeview, light areas of the screen are covered with black dots, like on peoples faces.  It looks like they're being plagued with flies.  
It does it on all digital channels. 
I've updated to the latest software, but no improvement.
I've tried two different outside areials, & one inside, with no change.  The TV says it's getting 95% signal strength, with signal quality 100%.
I can't see anything wrong with any of the setting, and have tried changing each to max or min.
Any ideas?

Black dots appearingHere is an example of the dots, note them on parts of the light coloured background, face & hand.  When the picture changes they may appear anywhere on the screen where there are light areas or faces etc.

Does a hard reset do anything? (if possible?)
I know it works well with the old's homecast box

Take it back to the place you bought it from - it's borked.

I think it is faulty, but to prove it to the retailer can sometimes be hard work, and they may want you to pay a deposit to get to tested etc. I think you are best to take photos and video it, and get them to test it instore. The worst problems are those ones that come and go, and never appear when it is being tested. They should just switch it for a new one instore with that sort of major problem.

Yep, get it back ASAP so it falls within their DOA period (if more than a week, you may already be too late, but kick up a stink), otherwise they may send it off for repair and you will be TVless until it gets back from Sony Service.

Odds on they'll be able to provide you with a loan TV... People who 'kick up stinks' seldom get looked after in my experience, human nature takes care of that.

Our Sony had a DOA digital tuner. They sent a tech out with a new board and it was fixed on site. But as above don't spend any time trying to fix it. It is faulty no questions.

Phoned up Sony who had no record of my online complaint.
Anyway, the NZ based woman I spoke to was very helpful & ran through the expected questions.  She also suggested a reset, which had no effect.

As the fault occured within 7 days, it was up to the retailer to replace the unit.  Sony provided a reference number to my phone call.  This enabled the retailer to quickly process the claim & I promptly received another TV which operates perfectly.
