replace the memory of ur unit, if not you should look for the power source of the memory and hang it off by removing the lead make sure that it does not contact the board.

Using a universal remote with numeric keys, input this code->319753 and press mute. This has to be done quickly, and the channels will change, but ignore that.
Use navigation keys to change the settings.
If it's in High security mode, then you are pretty screwed, unless you can find the green Master remote which has a few more functions.
If in Standard mode, then a universal should be fine.
It took me DAYS to find all this out, since I just picked one up last week, and I had the same problem.
I had to use 2 remotes to do it though, since my universal is old and clunky, but I had an old Philips multi remote for a video player as well, which accepted the direction buttons ;)
Hope that helped. If it's been solved for you, it's ok, since there might be others out there with these model of ex-hospitality(hotel) TV's.
Cheers from New Zealand!

Hello
Philips sets use a four digit code to control the v-chip. The override code for Philip sets is 0711, although it may say "Incorrect code" the first time to trick you. If "Incorrect code" is displayed, simply enter 0711 again. To use it hit the MENU key to get to the menus. Go up or down until you reach AUTOLOCK or SMARTLOCK, depending on the model, and push the "right arrow" key on the remote. Enter the override code, and enter it a second time if it says it is incorrect.
Once in the AUTOLOCK or SMARTLOCK menu, go to BLOCK, and push the "right arrow" key. Go to BLOCKING OPTIONS and press the "right arrow" key. Go to MASTER DISABLE and press the "right arrow" key so that it says "MASTER DISABLE ON". The v-chip is now reset.
OK.
