Can anyone help identify this problem? The TV is pretty much new and keeps crashing. Can go a few weeks without doing it, then it happens, its crashes and restarts and then it'll keep doing it every 40 mins or so. Ive tried factory resets etc, all latest updates downloaded, its like something in the TV trips, makes a loudish click noise, green (sometimes plain something stripey with purple) and then turns off and back on. Happens no matter what content source, e.g built in netflix, ps3, firestick, happens without any hdmi's plugged in as well.

Any help greatly appeciated!!

Many thanks.

Sam
