We are having a similar issue with this same TV - Phillips 42PF7320A/37. The TV turns itself on/off and makes a clicking noise when doing so -- until it finally goes dormant and the green light blinks on the front of the TV (in some cases this light turns red). We finally need to unplug the TV because it will not repond.
We purchased a small signal board (SSB) and replaced it yesterday. We thought this resolved the issue, but after 10 minutes, it did the same thing.
Any thoughts for us?

a 7 bliink error for this model is an 8.6 volt error normally caused by the y main overloading the power supply. disconnect the y main from the power supply and if the tv starts up check primary voltages per power supply sticker on pdp and if correct replace y main and y upper and lower buffer boards as they work together as circuit

First, I would try leaving the TV unplugged for an hour so the TV can discharge and reset itself.
If this doesn't work, it maybe something simple like a blown fuses inside the TV that needs replacing. Radio Shack or some electronic store will carry the fuses.
If the other two ideas doesn't solve it, we're talking about a power supply board related problem. I can actually look at your TV over the internet. But, the most common problem with flat panel TVs are the power supply board for the screen itself and the main power supply board for the rest of the TV. Commonly a bad capacitor or transformer will be on the board.
If you have some electronic experience and want to repair it yourself, you can sometimes find a Service Manual for your TV over the internet. Normally, costs less than $20. It will have diagrams, schematics, and part number list for the TV.
