I know Vizio is not the best brand but I got this almost free. The previous owner told me that sometimes it turns off in 3 hours and sometimes in 30 mins. Or any time in between. I'm going to disassemble an start troubleshooting but looking for any thoughts on what it could be. I will post pics soon.

Caps? -
Re: Vizio E47OVA Turns off at random
Technically it could be caps but not that likely. I know Vizio's have tons of other issues and usually use decent caps at least on the power boardComment

EEPROM on the main board possibly.Comment

Re: Vizio E47OVA Turns off at random
Can the EEPROM be replaced. I turned it in last night and worked for several hours until I shut it down.Comment

Re: Vizio E47OVA Turns off at random
Yes, but you need some decent soldering skills and preferably a hot air rework station. The chip is quite small. I just worked on this exact same TV and after replacing the eeprom and no change in the problem, I replaced the control board. Be very careful in selecting exactly the same board with a perfect match on all of the numbers on the large white sticker. There are several models that use that same board. It took me 2 tries to get it right.Comment

Ok so here's the story. I was watching tv one day when all of a sudden I heard a pop from the back of the tv set and rushed to unplug the set. By this time the tv already had smoke coming out the back. It was not storming or inclement weather that day to cause a power surge to the best of my abilities. When I opened the tv up, I found that the three capacitors on the psu (highlighted in red) were all bulging and looked they had exploded. I replaced all of them right away and when I went to start up the tv after the "fix" it started just showing the flashing vizio logo as soon as power... -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Vizio M60-C3 powers on, perfect logo, turns off. If you don't touch anything it will repeat this process by itself until it is unplugged. Not the "button board" since I disconnected the cables to the main board and the problem persisted. So I'm fairly positive something is going on with the main board, but want to know if there is a fix for this other than replacing the expensive mainboard, which may eventually have the same problem. Also, heat sink was hot as hell when this all started. Unplugged for a few days and same thing happens.

MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable to reset the computer. I disconnect the battery fully and then reconnect it and it won't turn back on. After letting it sit for a day I plug the battery back up, and the MagSafe 3 cable and it powers on and stays ons, once I plug in a USB C cable into the port closes to the MagSafe port it turns off and the Amber light turns off and won't turn on. No water damage, nothing, I want to do a DFU restore to wipe the computer since the customer stated they did an update and ever since it just decided to not work...

I am testing an old LG L192WS-BN monitor I have that gives an image, but has a backlight issue. When you turn it on the backlight turns on 1 second and it turns off, turns on again, 1 second and it turns off and stays off. Using a flashlight I can see there's still an image.
I replaced a bulged cap on the main board, but made no difference. I also got another exact same model monitor that has a broken ccfl (the connector got ripped from the panel and the main screen connector is also broken so I can't use this panel to test), tried using the main board from this one, same issue....
