We've had our Vizio VO42L since before 2010, and it's worked flawlessly this entire time. However, just recently it started emitting a high-pitched buzzing/humming sound. I followed the basic troubleshooting tips of just unplugging it for a moment, and even holding down the power button while doing so, all to no avail.
Furthermore, after I attempted these basic steps and powered the TV back on it would always begin visually flickering while the sound stuttered. After a few moments of being turned on this would go away, but it still periodically comes back.
I also disconnected every device from the TV, but it didn't have any apparent affect upon the problem whatsoever.
I've just ordered a new power cord, because Vizio claims this could be the problem, but I obviously have my doubts as to whether or not this will solve the issue at hand.
Meanwhile, I've also taken the back off of the TV after unplugging it, and currently have it set aside for further troubleshooting. My biggest question at the moment is what the most likely culprit is, and/or is there anything else I can do right now in order to isolate the issue here?
I've taken photos of the main board and power board, which I've also noted the model numbers of, but I'm hoping that I can be guided in the proper direction before I potentially start ordering a bunch of unnecessary parts.
Thank you.
