Product review (5 stars): Replacement for defective IR sensor on 42" Philips TV
My remote control works again! Took about 10 minutes to pop the back off the TV and install this thing. You need a #4 star nut screw driver head to get the back off. It's not hard to do at all, though, and if you are just a little bit handy you'll be able to do the repair. It does take some patience and persistence to unplug the two little wire leads from the old IR sensor...seems like they are going to rip but they don't if you are careful.

That being said, I will never buy a Philips TV again. The infrared sensor should *never* break in a TV and it looks like this is a major issue with Philips TVs.
