I found this snipit here

For the request concerning Philips dvdr 3460 H, to make, DVD, not disc on the screen, then 0086000, then OK.
The apparatus is slow to incorporate the data: to remake the manipulation second once if that did not go the first.
But the manipulation is sure to obtain the result.
Tried it by selecting DVD without a DVD inserted, then selected TUNER, opened the drawer, then entered 0086000 and OK. Nothing seemed to happen so I did it agai. Still nothing spectacular, just a blank screen. Tried a region 1 disc, it loaded, tried region 2, it loaded too. Magic!
My thanks to whoever found the hack and my apologies to those I have delayed from using it.
