20 Most Recent Philips 47PFL3603D LCD TV Questions & Answers

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.

We sell a repair kit for this board, which has the fuse, resistor and the IC that usually fails along with them.

You can find it at http://www.coppelltvrepair.com .

I've seen that board fail in at least three different ways, though, and this is the least bothersome of them.

We offer a repair service and have about 90% success even with burned boards. You don't pay any service fees if we can't fix the board.

Finally, when available we also sell boards ready for use with a trade-in option. That ends up a little more costly than a repair, though.

More than likely the old board just a, or a few, blow, capacitor(s). It you have a soldering iron, you can replace them yourself for just a couple of dollars.

Just look for puffed-up little can-shaped thingies, unsolder them, and buy replacements for a buck or two down at Radio Shack, and you should be "good to go"!

Easy fix, and cheaper than a replacement board.

I would think the /f7 board would work, if it has the same connectors as the /27 power supply board.
