Our 42" flat screen philips tv isn't working. the red light is flashing
Your TV is in Protection Mode right now. A part inside the TV has failed and the TV will not turn ON to prevent other parts from being damaged. The red light blinking is an error code for diagnosing the problem part on the one of the power supply boards. The problem boards that need to be looked at is the Backlight Inverter Board or the Main Power Supply Board.
There is a slim chance you can leave the TV unplugged for an hour so the TV can discharge and reset itself. But other than that, I would use the warranty if possible. The TV repair shop maybe expensive, so get some price quotes to see if it worth the trouble.
Unplug for 36 hours. Had same problem with my Sony

I had the same issue with 2 of these sets. It ended up being 2 capacitors were bad on the power supply. They are located towards the bottom of the board, you can visually see they were buldging and leaking slightly. I replaced them with 2 I salvaged out of an old computer (of same values) and the tv works as it did before.

I bought a plasma Philips 42 inch model number 42PF7320A/37 also 18 months ago. The exact same thing is happened to us. The screen would go black every since we brought the tv after about an hour of watching it. Then the other day it went black and never came back. The red light in front is blinking and they are saying we need service!!!!!! A $2000 TV lasting 18 months. I am trying to get Philips to be accountable, I am very upset with this product.

SOURCE: tv turns off and I get a red flashing light on
After looking through the user manual I could not find any error codes to diagnose your problem. I suggest calling Phillips Customer Support at 1-888-PHILLIPS.

This fix was posted on similar problem, worthy of repeating: Replaced 3300mf 10V capacitors at PS. Both had bulged slightly. Upsized to 25V as the previous solution poster had suggested 16V but I could not locate 16V so used 25V and TV is back to normal!
