PN51E550D1F lines and picture jumping at 1080p

by tg88 - 11/6/12 11:17 AM

I have the PN51E550D1F I thought is was the power cable.
It has been replaced still does it.

The lines appear and screen jumps only at 1080p with anything that plays 1080p.
My xbox, Lg blue-ray and my Sony home sound dvd system and driect tv and directv cinema (1080p)
The picture jumping and lines appear at just the menu screens on all these devices and while using them, playing a game, or watching a movie.
Tried new cables, factory reset and new firmware.
But I have narrowed it down to netowrk traffic going to the tv, or in the tv itself.
My PN51E550D1F is a smart tv and i have the internet connected.
If I kill the erthernet connection (removing the cable) and kill the wireless connection the lines and jumping stops.

Erthernet cable disconnected, wireless on = lines and jumping
Erthernet cable connected and wireless off = lines and jumping
Erhternet cable disconnected, wireless off = no lines and no jumping and tv picture is perfect.

I update the firmware online through the tv
Last ver 001023
I did notice this started around firmware 001017 or so.
Can Samsung just reproduce the issue, trying the internet connection ?
