RE LCD Interference

I had the same problem with a Philips 32 inch tv. The solution I have used after scanning through many blogs and forums, is to cut a small piece of plain white paper and apply over the IR sensor on the sat box. This seems to block the stray IR from the TV whilst allowing the stronger, more direct IR from the sat remote through. It also seems that the bigger the TV, the more IR you get from it, so if a single piece of paper won't work, try adding a second or even third layer of paper over the sensor.
