Did an update yesterday that none of the other similar/ identical Philips TVs in the house didn't get and cannot find, the TV froze on an all green screen for 2 hours mid update and I had to switch it off at the wall to fix it, when it powered back on the update finished and it worked fine, after around 3 or 4 hours the screen started to randomly turn off and back on again at various intervals, worried this was an overheating issue I left the TV unplugged overnight and would try again this morning. Today all that has happened has been shorter and shorter intervals between restarting and now won't even get to displaying a picture, stuck cycling between the Philips Logo and the android loading screen. Anyone know any solutions? Currently trying to load a USB with an older version of android TV to hopefully boot from
Sorry to hear you are having trouble. Philips smart TVs are, essentially, expensive bowel movements with some LEDs around the back. Stop into the Philips forums to see if you can get someone to help you. (Short answer: you can't. If you're lucky they might send you a PM asking if you tried unplugging it or updating the software after which they will never respond again).
On the other hand, you'll be able to enjoy the company of hundreds of other duped Philips smart TV owners there, all of whom have bricked and/or unusable TVs.
