Why is there a dark bar in the middle of my Vizio M658-G1 TV screen?
I have a Vizio M658-G1 that is just over 1 year old. There is a dark bar about 16 inches wide by 4 inches tall in the middle of my screen. It’s present on all inputs and also color calibration screens. It is intermittent and seems to go away randomly. There have occasionally been 2 bars in the middle of the tv. I’ve done a soft power cycle and also reset the tv to factory settings. Neither fixed the problem. Any ideas what to replace?
