VIZIO M3D550KDE 55” Class LED Smart TV problem getting worse

This video clearly shows our VIZIO M3D550KDE television problem is getting progressively worse. We have been in contact with VIZIO support – I sent them the requested pictures but have not heard back. Crazy schedule hasn’t offered us any time to call VIZIO again.

Video clearly shows that a tap on the back of the television resolves the problem. I don’t think this is something you should have to do with a new TV. It is clear that the problem is not signal related. The issue is clearly hardware related – something isn’t working right inside the television.

My tap sounded much harder than it was. A light tap normally resolves the issue.

This is a good TV – especially for what we paid – when it works.
