My TV is a 60 inch Vizio M60-C3. I turned off my TV one day and didn’t turn on again. The status lights functioned as they were supposed to, showing that the tv was turning off and turning on when pressing the power button. I gave up and unplugged the tv for a few days, before plugging it back in at a later date. At this point, the TV turned on and functioned properly. However, after two days, the TV refused to turn on once again. I have unplugged it once again and will try and reset the software if the TV turns on again. What should I do? What is the Problem?
I’ve known this to happen with another model of flatscreen when the power supply board when bad. In that case it was the proverbial faulty capacitor, but it was less labor intensive to replace the PCB. Similar part here to my repair for your model: https://www.ebay.com/i/383465729628?chn=… Once you get into the casing and have the part exposed the replacement should just be reverse of removal. In my case the protocol was to remove all screws holding the plastic back cover in place, pry open and the components were then visible. There’s not currently a guide available for this on your model.
