I experienced EXACTLY the same problem with my one week old 46B8050
I had to send mine to a service shop - and it turns out to be a production failure.
There are two IC's on the mainboard, which for cooling reasons are factory covered with a small drop of silicone. That is - they are SUPPOSED to be covered with silicone. On my TV - they had missed one of the IC's by some millimetres - and that probably caused the IC to overheat - which in turn caused the main controller board to malfunction.
Now I have been told that the entire panel will have to be replaced - and I am also told that for my 8-series this has to be ordered from abroad (dont know which country) - and the supplier told the service shop that delivery time on this was one month!!
I tried to get an RMA - and have a new TV instead of waiting one month - but Samsung Norway insisted that a new panel had to be ordered. And even though the supplier confirmed a one month delivery time - Samsung said that the panel had to be ordered anyway, an they would not accept an RMA request until two weeks had passed without the panel arriving the service shop. Wednesday two weeks has passed since the service shop ordered new panel - and Samsung will not accept an RMA request before that.. And then Samsung will take one more week to process the RMA, and finally it will take at least another week shipping the new TV to me.
Now I already have waited one month since sending the TV to the service shop, and it will take at least two more weeks before I get the TV back.
This is not good for Samsung's customer treatment reputation !!!
Not only am I without TV for one and a half month - but during this period I also have to pay Canal Digital subscription for programmes which I because of Samsung can not view !!
Hi there. Thank you for taking time to read this.
This morning when I turned on my TV, there was something completely wrong with the picture. It seems to be inverted and very very bright, almost completely white. Same goes for the build-in menu. I attempted to disconnect everything. Reset the picture in the menu. Turn off / on. Nothing helped. Same story no matter if it's Antenna, Xbox360 or DVD. It was fine yesterday.
Does anyone in this forum know what my problem is ? Is it settings ? Is it hardware failure ?
It's just a few weeks old. 40 inches LED tv from Samsung. UE-40B6050.
I have uploaded a picture if you want to see what it looks like..
