PHILIPS 42PF7220A/37 S42AX-YB01 wont turn on

I think its something on the picture frame board or on the line output board. I would sway to the line output simply because I think but not sure that error code is linked to the line output stage plus when you unplugged the cable the voltage seems within parameters. Good luck.

Most likely the problem is your Philips 42PF7220A/37, may not have the same power supply board as other people are talking about on the net. So, the C2074 capacitor maybe under a different number.
The best thing I would do if I had the same problem is to get a Service Manual on the internet. It cost about less than $20. Right now your TV is in " Protection Mode" and blinking a trouble code with the red light. The Service Manual will tell you what the red light blinking code means. Plus, it will give you schematics, part numbers list, and test point for diagnosing. It's better to have a manual for fixing than going by guesses over the internet.

Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.
