Question about Philips 47PFL3603D LCD TV
This is alsmost identical to my problem, only variable change is i have Comcast neither remote will get the unit to turn on or anything. The white led in the lower left corner is lit but doesnt react when any button on either remote is pressed. I have done all the basics verified the battery position and even unplugged he unit for 60+ seconds....no change in state. I also verified that i have the lastest software
One thing you can do is take your cellphone's camera, point the remote at the camera, and press a button. You should be able to see the infrared sensor firing.
If you can verify that, your remote's fine.
In this case, what you have is a bad IR sensor board. The part # is:
313926859182. Right now, there are so many of these things failing, that finding the original might be difficult.
Don't fear, though; it's a small part. And, best of all, it's cheap. Expect to pay around $5.00 for the part, maybe a bit more, maybe less, depending on the supplier.
Now, if you are handy with a power drill (fitted with an octagon/star bit for the back of your set), you can remove the 20 or so star-bit screws from the back of your television. Don't worry about putting the set on the floor. If your TV is on a stand, simply turn it around. You'll need to remove the stand screws, but you won't need to take the TV off of the stand.
Now that you've taken the screws out and removed the back cover, look in the lower left hand area of your set. You'll see a 4 inch long circuit board with 2 cables running to it. Pull the cables out (they'll come out easy). Remove the 2 star-bit screws.
One of the board's sides is under a plastic tab. Lift the board out of its slot from the other side.
Put your new board in, reconnect the two cables, reassemble the back and you are set to go.
Expensive repair for a few bucks and a better IR sensor.
This advice assumes that the control buttons (power, volume, channel) located on the side of the set still function. It also assumes you are able to use those buttons to power on the set and verify that you still have a picture on the screen.

I also had the same problem with my IR sensor board 313926859182.
I was also recommended before buying the new part to try to alter the old IR board by scraping off the capacitor sticking out just to the right of the connectors leading up to the power/volume controls on the TV. The rationale is, if I am going to replace the part anyway, why not try to mess with it?
Funny enough, scraping off the capacitor worked perfect, now I saved myself $20 and have a working remote control now.
