Flickering area on Vizio 4k
I have a 4k Vizio that’s a few years old. Nice picture. Always been pleased with it. Today I noticed some slight flickering on the left side. It’s not overly noticeable but it did catch my eye. It’s a rectangle shape. When put the tv on a static image, you can see a dark rectangular area. There’s still picture but I’m worried it may not be for long. Any ideas??
