UE55MU6670UXXU Black lights streaming up TV

[Littlebadwolf]

I've recently noticed what appears to be black streams of light going up from the bottom of the TV. I have a feeling it's to do with the LEDs, as it looks like an absence of light and/or colour. I've tried the picture diagnosis and know it's not an HDMI issue as it happens on the apps as well. It's most noticeable on light colours, and managed to get a picture of it on an entirely white background here. Is there anything I can do to fix this, maybe with the internals of the TV?

Hi @Littlebadwolf ,

Has the TV passed the test or failed it? What software version is this currently running on? You can check this from Settings> Support> About this TV/Contact Samsung.
