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

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
