Philips power supplies are junk. In general, if the scaler/lcd board/or an invertor has failed, you get a flashing LED on the power light.

If it's dead, then check the fuses on the psu board, and see if it's caps have popped. There are four electrolytics on the output side of the PSU that are under-rated on most Philips TVs, so these bulge/leak/explode.

With respect to any of these sets, power supply caps are a pretty common item.
