This is usually an indication that the power supply has failed. It is also possible that there is a short or failure on another board, and the powe supply is in the protect mode.
The set would require proper troubleshooting by an experieced TV tech who knows the type of set you have.

I had a similar problem with my 42 in Philips LCD HDTV. Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems. Here are some options for you. 1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?) Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk. 2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. I would definitely shop around though. 3. Remove and then replace individual faulty caps. This takes some soldering skill. Caps are inexpensive and if you can take care of it yourself it will save you hundreds. This may be your problem. If you determine that it might be. I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help. Hope this helps and if it does please rate it accordingly. Good luck.

Tries tv unplug,replug it back like about an hour later for the tv resetting itself back to the factory setting.Tries again,tv should be working.If still getting no power at all than the tv Tuner board is dead,because pictures freezing and dies completely is the causes so it is not power supply board problems.The tv Tuner signal board is the causes,that the board where the incomming broadcasting signal cable plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish tv Tuner signal board for the replacement.
