I am having problems with seting up my DNS on my tv it wont apply it (I need to restart my tv for it to apply DNS addresses) I have tryed with that button that is on the back of it but since I installed an update all that button does is enters stand by mode I have tryed unpluging it but this does not work either then I tryed to reinstall the tv but also does not work
strange that even the manual doesn't even say how to restart or shutdown from what I can see on their website.
try holding the power button on the remote for about 10 seconds and see if it does anything, on sony tv's you can goto settings > about and restart is there check for similar settings on your tv
surely unplugging it for 10-15 min will do a dirty shutdown and boot up again when plugged in
edit: also try holding the power button on the back of the tv for atleast 10-20 seconds and see how it goes
