Thick, Defined, Vertical Black Line on Samsung QN65Q80TAF

[connoro21]

Hey everyone! Our TV suddenly got a thick, defined, vertical, black line, illustrated in the picture. Any ideas on a diagnosis/fix? I've opened it up and wiggled/undone/reattached all the cables I could find, as well as used some compressed air to clean it up, but to no avail. Also bought a new power cable, but that didn't work either.

Thanks!

Is something in the screen making it leak? I've no idea what is behind screens, but it looks like a leak.

Hello @connoro21 Thank you for posting about this. I completely understand your concerns with the line appearing on the tv. Are you able to navigate through channels on the tv? If so does the line appear on all sources? Does it occur during the picture test? Here's a link that might be helpful: https://www.samsung.com/au/support/tv-audio-video/picture-test/

Hello! I will try the picture test after work today, but it does appear on every channel/app. The only time I don't think it's there is when turning on the TV, as the screen turns to a black with the Samsung logo, the bar doesn't seem to be there, but the screen still emits a black light I believe.

Okay! Please let me know when you try it. Also, when the screen turns black do you hear sound playing?

Hello! Have you had a chance to give the picture test a try?
