Our TV has an image problem (pun intended)
Our 6 or 7 year old 70" Sharp Aquos LC-70C7450U TV has an image problem. I have three sources connected to the TV and all three have the same problem. I've tried various picture settings and none correct the problem. Because pictures are worth thousands of words, I've attached several that show the problem. The leftmost has the problem circled. It's a fairly wide vertical band. Sometimes the image is fine in that area. But the problem is becoming more and more constant to the point I have to fix it.
Anyone familiar with this problem and, if so, can it be fixed and what will it take to do that?
