There are ways to downgrade your TV if you search the forum. They have been mentioned several times...
I have never downgraded (as it is NOT advised by Philips and may cause problems), but I thing you have to close the TV from the mains switch, and keep pressing the ok in the remote, while you give back power through the switch again.
