I have a Philips 42PUS7809/12 stuck in a constant reboot loop. As soon as the power is plugged back in it starts up, shows the Philips logo, displays the input selected and then goes black and starts this all over again. In searching about this there's a lot of posts about Android TVs but I do not believe this is an android TV model. I have tried using a dedicated socket, and leaving it unplugged for a few minutes, an hour, and 24 hours between trying again but it's still the same. I've also tried holding down the button on the back while it starts up but again there's no change in its behaviour at all. Does anyone have any other advice? I have the tools to get the back off and replace parts if necessary I just can't find any advice on this issue.
