I have a Sharp Aquos LC-70LE847U that was purchased in June of 2012. I have searched this thread and googled for the same issue I am posting about and have not found it duplicated in this model or to the same degree on any model.
For the past week I've had a 3.5" stripe or band down the center of my screen. The band shows up on all inputs and tv menus and is extremely noticeable on lighter backgrounds and images. The band is a blackish/dark grey "mesh" with perfect lines. You can see the image thru the mesh.
I've had several other issues with this set such as netflix freezing and being stuck on all screens, full screen "pixilation", and apps freezing but nothing I could not fix with a power plug reset. My TV has the newest firmware, I have done a factory reset, and the issue was the same between both the reset and firmware updates.
I have contacted Aquos advantage and they created a ticket. I was told I would receive an emai to send proof of purchase and a picture procedure. I waited two days and emailed directly. 2 days later I received a response to my email and was told to send proof of purchase. 5 days after sending proof of purchase I was told to take pictures of the screen and send them to them so they can diagnose the issue before repair. So far overall I am disappointed in service. All of this red tape could have been told to me from day one when I called or at least in a single email when I finally did get a response. It was a cumulative 10 days of waiting to get all the info SHARP needed me to send...
Anyways, I snapped these pictures tonight. Though the issue is on all inputs/menus/etc; All of the pictures came from the HDMI of my laptop so I can show a good light background and highlight the problem. Please disregard the lighting halo in the top right of the picture. That was the kitchen lights and not a defect in the TV. Also, I have ZERO clouding so it will suck if I have to have the TV replaced outright and worry about that issue!
I will be sending these to Sharp to await for their engineers to decide how to fix my TV, await a service call, await a service appointment, be told they do not have the parts, await the parts, be told my TV needs to be replaced, wait for replacement TV, etc..etc.. I am glad I purchased an extended warranty.....getting the TV repaired seems to take extended time.
Has anyone else had this problem with our TV or any other and how did the repair process go? Thank you in advance for your time.
