    Set automatic Date and time not working, it getting defaulted to Feb 2014 date even though I set current date manually after power off and on the TV. Please suggest even after replacing with new board same problem still persists.

    Automatic date & time setting normally relies on the NTP protocol which will require a working internet connection. So when your TV doesn't have a working internet connection that might be the problem.

    Thanks for the response. I do have a working internet connection and Im able to browse after setting the time manually. Everytime power off and on the TV date will reset Feb 2014

    If I had to guess I would say it's the power supply unit that's gone bad.

    When you turn off your TV I believe it's still supposed to supply the main board with just a tiny bit of power (called "standby supply) to keep your personal settings intact. If it doesn't, then everything would revert back to default settings.

    If you watch the video here, he starts to talk about the power supply around the 3:30 mark.



    In this video, the power supply turned out to be fine but since you stated that you've already change the mainboard this would be my next step.

    Good luck

    As above, I'd guess a power issue, but...

    A smart TV is essentially a specialised computer. A PC usually has a button battery on the motherboard. If this is dead or absent, the computer cannot retain the time when switched off. I don't know if this is true of a TV (I'm doubtful), but you could check. The battery should last for years.

    Digital TV services usually include TV guide data - I'd guess timing information also arrives in the signal - so even if the TV only relies on mains power and has been completely disconnected, it should be able to update itself soon after being switched on if connected to a broadcast signal.

    So, is your TV connected to such a signal? When switched off, is it completely disconnected from the power supply? (I.e. Not in standby?)

    Is it possible that there is a setting for updating the clock via the internet (network time, mentioned above) and this has been switched off?

    Finally, is the TV still under warranty? I'm assuming LG replaced your board for this issue & I'm therefore surprised they didn't actually check if they had solved the problem. It also seems unlikely that a new board would have the exact same issue. If this is the case, get back to them.
