SOURCE: Philips Tv won't power on.......
Try plugging in the USB drive and HOPE that the P.O.S.T. during that 2 second period grabs the upgrade, but I must tell you that this is a hail-mary pass.
After that, it's DOAville!!

The TV is on protect mode.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.
If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.
Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.

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 ofcourse) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 yearsinstead of 10-20. The capacitors failprematurely due to a lack of preservatives. Unfortunately, they were installed in allsorts of devices and cause a wide range of failure problems. Here are some options for you.
1. Have it fixed by a professional $$$$$$$???????
2. Open your TV and find PSB. Checkfor faulty caps. If you find some (bulgedor leaking) bad caps replace the entire board. The entire board costs around $250 right nowbecause they are in high demand right now. They can be found at tv-part.com but supplies are limited.
3. Remove and then replace individual faulty caps. This takes some soldering skill. Caps are inexpensive and if you can take care of it yourselfit will save you hundreds.
I have a tip/tutorialon this site that may also help. Itgives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing the Philips Turns/shutsoff on its own problem. I'mworking on uploading pictures to help guide people though the process aswell. Let me know if I can do anythingto help. Hope this helps and Good luck. Kaufman605
