SOURCE: Philips 42PF7320A/37 won't power up Led blinks 7 times

This what to do measure from the logic board which is located under the small signal board and have the AV jacks connected to it. If the voltage is 3.1 or close the problem is with the power supply or a boar connected to the power supply. Unplug the set. Disconnect the Y main board first that will be on the left side of the set facing the back. Plug the set back in if the led is solid replace the Y main and the Y upper lower. If still blinking plug the Y main back in and unplug the X main which is on the right side facing the back. If the led is green replace the X main. If the led is still blinking replace the power supply.
But if the volts are 0 the problem is the SSB or the logic board. In that case take the (SSB) small signal board out the set and place 1 jumper on J8003 and another jumper J8004 of the left side of the power supply. Then place 1 jumper on CN2072 of the lower left part of the logic board. Plug the set back in if the set displays a white, blue ect screen replace the SSB. If not and on the logic board you don't have 1 solid blue led and 1 blinking led data is not flowing and change the logic board.

SOURCE: Philips 42pf9630/37a, Blink red LED 7 times, No Picture No Sound

7 blinks indicates a bad buffer board, usually I replaced the Y board and the buffer/s about $500-600 in parts. but before you buy anything open the set and look at the power supply if you see two capacitors that look swollen , bulging on top they need to be changed and may solve the issue. the power supply is middle top . If you are not wanting to repair it yourself then know that you do have some circuit board repairs needed.
thanks

TH 42PV8H A MY TV POWER NOT ON RED LED 2 TIME BLINKS


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

Blinking codes details to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.
