Just had the same problem and used a cheap $4 universal remote with Magnavox code "0224" and it turned on! Hope this helps guys!Put code in twice if it doesn't work the first time.Another one said code 0711. if first one does not work.

Hi,here i have added link to the user manual for your tv. User manualHope this will help you to rest the tv.OK

You will for sure need to borrow a remote from someone to do this. But I will give you the way to unlockit just in case you can get one. 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. Good Luck

Its horizontal output section circuit should be troubleshooted. Contact any experienced service technician. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.

What model number of the remote do you have? I also have a GE universal remote and I have used it on over 30 tv's and every single 1 worked. Do you do the autoscan or put them in manually?

I would check the Flyback, and horizontal output transistor. Could also be a grounding issue. If you're not familiar with fixing them get it serviced.

Please clarify your question if possible.

If from the set and not a box you need the original remote control.

It may be in the Demo mode, usually a combination of front buttons or the remote may have a button will clear it.Try combinations of channel and vol down or one down and one up, failing that call philips customer service.
