PN51E550D1F lines and picture jumping at 1080p

by tg88 / November 6, 2012 3:17 AM PST

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 ?

Any resolution under 1080p, 1080i, and down with internet connected is fine.
Just when internet is connected at 1080p the lines and jumping appear.

the lines are like this

The Look like white horizontal thin lines scratch lines.
They flciker when there is network traffic going to the tv.
When there is no netowrk traffic there is no lines or picture jumping.
this page on troubleshooting is where i started.

just checked does it with all connections removed and composite red, green, blue cable.
I also moved the power cord and hdmi cables apart to make sure nothing was being transfered into the hdmi cable, ethernet cable,like emi / rfi interference.
Power cable and ethernet cable has toroid choke coils installed as directed in the manual.
All of my hdmi cables are high speed with ethernet.

Hi adfar206 and others,

I'm very sorry this is happening. Tg88 has been helpful enough to give me a good bit of data. For those who feel inclined to help me gather more data, contact me over a social media channel. As most people use Facebook, I'll suggest you go there and use the support form. Ask for me by name and provide your model code, serial number, and firmware version. Details for contacting by the Facebook Support Form can be found here: http://forums.cnet.com/7723-13973_102-542437/service-issues-click-here-for-help/

re its SyncePlus
by tg88 / November 15, 2012 3:26 PM PST

Found the issue that is causing the picture jumping.
If you disable SyncPlus app in smart hub the tv is perfect.
Enable it, lines and picture jumping.
So it is an issue with SyncPlus.
I have it disabled and the tv has been perfect and internet connected (ethernet cable).

Firmware ver 1023.2
Smart Hub ver 4.5101-5.0
Smart Hub updated 11-14-2012.

They will get to the bottom of it.
Will take some time but I am sure they will find out why.
