Nice, I was also confused about blurred messages issue
Thanks for the pictures, excellent pix
OK, take your time
Sorry to hear that, do you still get sound from TV speakers?
OK, it is backlight system failure in TV that made screen dark, it is either power supply board failure that provides voltage to backlight inside screen or the backlight LEDs inside screen are not working any more to generate light to glow the screen.
Power board is located on left at rear of TV and the connector on top left of power board that goes inside screen provides volts to backlight system.
It needs further troubleshooting in TV with multimeter/ backlight tester to determine that is bad to get it replaced if you have plan to do it yourself, however, if backlight LEDs found bad then it is serious issue and should be done by experienced TV tech to replace LED strips because display panel/ the screen will take apart for it.

It is an LCD TV, LED is backlight system to light up the screen,.
Display panel consist of many things, LCD is glass sheet that has liquid crystals that make an image and LEDs are used to generate backlight behind that LCD sheet to present that image to viewer.
sharp lc-70le660u calls LED TV..
Are those vertical lines in black and full from top to bottom?
Vertical lines on screen is always problem with LCD sheet and has nothing to do with backlight system, sorry about this news.
You will get those lines once screen gets light up and only fix is to replace entire screen of TV which is of course not feasible because display panel/ the screen replacement would cost more than a new TV price of same size.
I hope these info will help. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page so I can get credit of my work on website.Thank you.
OK, then it is definitely backlight LED strips issue and power board would be fine.
Vizio is nice brand for low budget TVs, high end brands are Sony, Panasonic, Samsung etc, currently these flat panel TVs (LCD, LED etc) last few years say 3-4 years so do not expect them for more than 3-4 years service.
I understand that, but they want to increase the sales.
It could be couple of strips that went bad, once you open the screen then look for burn marks on LED strips to see how many of them are defective to replace.
Usually at least/ minimum 4 strips around the edges of screen in small size TV and bigger screen would have more some times 20 or more strips inside, it depends what kind of screen that TV has utilized.
Yes, it would have quite a few but not sure how many have defective/ should be replaced.
Much welcome, wish you the best~
