Grey patches on Sony Bravia TV

[Radio Fixer]

Went through all the router settings and never found "uPNP" (what ever that is).  Router is a TP-LINK  (TL-WR1043ND).

So stumped on that one.  Most features are turned off as the Mrs only uses it for e-mail for a Laptop and a bit of Internet.  No file sharing, no printing from laptop etc.

   
   

To understand all this I would need to go on a Course and I was pretty good around PCs when working but thast 15 years ago.  Wow! how time flys.
