#USB TV ANTENNA FOR VIZIO SMART TV CODE#

I can imagine there are points in the code where the default action in response to some error condition is to put the TV into the exact same state I'm seeing now. I have a hunch that the TV's hardware is ok, that this is some sort of glitch in the firmware. at this point I can safely assume that either the problem is *not* the power supply board, or the replacement power supply board I bought online has exactly the same problem as mine (certainly a possibility I'm sure the board I purchased was used). I went ahead and swapped the boards, powered the TV back on, and within a couple of minutes it failed again with exactly the same symptoms. It was an exact match to mine, right down to the board's manufacturer, part number and rev letter. Since most of the failed cases I read about turned out to be a bad power supply board, I went ahead and purchased one online. And no one described their TV's logo as still being lit when the TV failed. In fact, if I then press the power button on the remote, the TV turns back on and all is well again (picture and sound) until the next time it decides to randomly turn itself off again.ДЄfter doing some hunting around online, I found many other VIZIO customers complaining of similar symptoms, although in most of those cases I the TV either failed completely (wouldn't turn back on), or the user had to unplug the TV, wait 10 or 15 secs, then plug it back in to get the TV working again (I've never had to do that). Other than the brightly lit logo, the TV appears to be in its normal off/standby state.

When it happens, there is no picture or sound, the same as if I had manually turned off the TV via the remote, but with one exception: the VIZIO logo on the bezel beneath the screen remains lit, and is 'brighter' than it is normally when the TV is on. The usual pattern is it happens a few times each evening. By random I mean it might not happen for a few days, then happen several times in the course of a minute. A few months ago it started randomly 'turning itself off'. I have a VIZIO 42' LED TV, model E422AR, about 3 yrs old (out of warranty).
