I have a display issue that I could use some assistance on.
Summary of my setup:
B7 is on the wall above the fireplace (approx. 5 feet from the floor) slightly angled down
HDMI cable run through the wall to Yamaha receiver, all components connected to receiver
Components consist of Oppo UDP203, Apple TV 4K and Comcast cable box
I bought a B7 back in Sept. 2017. Over the winter, I noticed a transparent horizontal line that runs across the screen approx. 1 inch from the bottom. I noticed the line most often with 1.78:1 content, but I sometimes noticed the line with 1.85:1 and 2.35:1 (traveled with the image and didn't stay at the bottom of the screen). The line was much smaller with the different aspect ratios, but it was noticeable if you were looking for it. It did not matter if the content was from the Apple TV, Oppo or Comcast box.
To troubleshoot, I've tried a couple of things.
1. I've toggled 'Just Scan' on and off and played around with the aspect ratio settings. Line still present.
2. I simply switched the main HDMI cable from input #2
. Line still present.
3. To hopefully rule out my HDMI cable, components and receiver, I connected a separate Apple TV directly to the TV via a separate HDMI cable. Line still present.
I made the assumption based on these tests that the issue lied within the display and not any one component or cable. I submitted a trouble ticker to LG and a local representative from an A/V service company came to my house. He agreed he could see the line, but when he did a video call with LG service the technician could not see it via phone. Therefore, they would not do a screen replacement, but said he could swap out the video card.
Before, I did either I wanted to get some opinions. I can follow-up with some pictures, but it has been a bit challenging to capture the issue with a camera.
Any suggestions on additional troubleshooting to do or follow-up actions would be welcome. Thanks in advance.
